Apollo

Apollo or Apollon is one of the  Olympian deities in classical Greek and Roman religion and Greek and Roman mythology. Apollo has been recognized as a god of archery, music and dance, truth and prophecy, healing and diseases, the Sun and light, poetry, and more. One of the most important and complex of the Greek gods, he is the son of Zeus and Leto, and the twin brother of Artemis, goddess of the hunt. He is considered to be the most beautiful god and is represented as the ideal of the kouros (ephebe, or a beardless, athletic youth). Apollo is known in Greek-influenced Etruscan mythology as Apulu.Krauskopf, I. 2006. "The Grave and Beyond." The Religion of the Etruscans. edited by N. de Grummond and E. Simon. Austin: University of Texas Press. p. vii, p. 73-75.

As the patron deity of Delphi (Apollo Pythios), Apollo is an oracular god—the prophetic deity of the Delphic Oracle and also the deity of ritual purification. His oracles were often consulted for guidance in various matters. He was in general seen as the god who affords help and wards off evil, and is referred to as , the "averter of evil".

Medicine and healing are associated with Apollo, whether through the god himself or mediated through his son Asclepius. Apollo delivered people from epidemics, yet he is also a god who could bring ill health and deadly plague with his arrows. The invention of archery itself is credited to Apollo and his sister Artemis. Apollo is usually described as carrying a silver or golden bow and a quiver of silver or golden arrows.

As the god of mousike, Apollo presides over all music, songs, dance and poetry. He is the inventor of string-music and the frequent companion of the Muses, functioning as their chorus leader in celebrations. The lyre is a common attribute of Apollo. Protection of the young is one of the best attested facets of his panhellenic cult persona. As a , Apollo is concerned with the health and education of children, and he presided over their passage into adulthood. Long hair, which was the prerogative of boys, was cut at the coming of age () and dedicated to Apollo. The god himself is depicted with long, uncut hair to symbolise his eternal youth.

Apollo is an important pastoral deity, and was the patron of herdsmen and shepherds. Protection of herds, flocks and crops from diseases, pests and predators were his primary rustic duties. On the other hand, Apollo also encouraged the founding of new towns and the establishment of civil constitutions, is associated with dominion over colonists, and was the giver of laws. His oracles were often consulted before setting laws in a city. Apollo Agyieus was the protector of the streets, public places and home entrances.

In Hellenistic times, especially during the 5th century BCE, as Apollo Helios he became identified among Greeks with Helios, the personification of the Sun.For the iconography of the Alexander–Helios type, see H. Hoffmann, 1963. "Helios", in Journal of the American Research Center in Egypt 2, pp. 117–23; cf. Yalouris 1980, no. 42. In Latin texts, however, there was no conflation of Apollo with Sol among the classical Latin poets until 1st century CE.Joseph Fontenrose, "Apollo and Sol in the Latin poets of the first century BC", Transactions of the American Philological Association 30 (1939), pp 439–55; "Apollo and the Sun-God in Ovid", American Journal of Philology 61 (1940) pp 429–44; and "Apollo and Sol in the Oaths of Aeneas and Latinus" Classical Philology 38.2 (April 1943), pp. 137–138. Apollo and Helios/Sol remained separate beings in literary and mythological texts until the 5th century CE.

Etymology

Apollo (Attic, Ionic, and Homeric Greek: ,  ( ); Doric: , ; Arcadocypriot: , ; Aeolic: , ; )

The name Apollo—unlike the related older name Paean—is generally not found in the Linear B (Mycenean Greek) texts, although there is a possible attestation in the lacunose form ]pe-rjo-[ (Linear B: ]-[) on the KN E 842 tablet,R. S. P. Beekes, Etymological Dictionary of Greek, Brill, 2009, p. 118. though it has also been suggested that the name might actually read "Hyperion" ([u]-pe-rjo-[ne]).

The etymology of the name is uncertain. The spelling  ( in Classical Attic) had almost superseded all other forms by the beginning of the common era, but the Doric form,  (), is more archaic, as it is derived from an earlier . It probably is a cognate to the Doric month Apellaios (), and the offerings  () at the initiation of the young men during the family-festival  ()."The young men became grown-up , and Apollon was the  (The Great Kouros) : Jane Ellen Harrison (2010): Themis: A study to the Social origins of Greek Religion Cambridge University Press. pp. 439–441,  According to some scholars, the words are derived from the Doric word  (), which originally meant "wall," "fence for animals" and later "assembly within the limits of the square."The word usually appears in plural: Hesychius:  (),  ("folds"),  ("assemblies"),  ("elections"): Nilsson, Vol. I, p. 556Doric Greek verb:  ("to assemble"), and the festival  ), which surely belonged to Apollo. Nilsson, Vol I, p. 556. Apella () is the name of the popular assembly in Sparta, corresponding to the  (). R. S. P. Beekes rejected the connection of the theonym with the noun  and suggested a Pre-Greek proto-form *Apalyun.Beekes, 2009, pp. 115, 118–119.

Several instances of popular etymology are attested by ancient authors. Thus, the Greeks most often associated Apollo's name with the Greek verb  (), "to destroy". Plato in Cratylus connects the name with  (), "redemption", with  (apolousis), "purification", and with  (), "simple",The  suggestion is repeated by Plutarch in Moralia in the sense of "unity". in particular in reference to the Thessalian form of the name, , and finally with  (), "ever-shooting". Hesychius connects the name Apollo with the Doric  (), which means "assembly", so that Apollo would be the god of political life, and he also gives the explanation  (), "fold", in which case Apollo would be the god of flocks and herds. In the ancient Macedonian language  () means "stone,"R. S. P. Beekes, Etymological Dictionary of Greek, Brill, 2009, p. 1168. and some toponyms may be derived from this word:  (Pella,. the capital of ancient Macedonia) and  (Pellēnē/Pellene).Nilsson Vol I, p. 558

The Hittite form Apaliunas (d) is attested in the Manapa-Tarhunta letter.The reading of Apaliunas and the possible identification with Apollo is due to Emil Forrer (1931). It was doubted by Kretschmer, Glotta XXIV, p. 250. Martin Nilsson (1967), Vol I, p. 559 The Hittite testimony reflects an early form , which may also be surmised from the comparison of Cypriot  with Doric . The name of the Lydian god Qλdãns /kʷʎðãns/ may reflect an earlier /kʷalyán-/ before palatalization, syncope, and the pre-Lydian sound change *y > d. Note the labiovelar in place of the labial /p/ found in pre-Doric Ἀπέλjων and Hittite Apaliunas.

A Luwian etymology suggested for Apaliunas makes Apollo "The One of Entrapment", perhaps in the sense of "Hunter".

Greco-Roman epithets
Apollo's chief epithet was Phoebus ( ; , Phoibos ), literally "bright".R. S. P. Beekes, Etymological Dictionary of Greek, Brill, 2009, p. 1582. It was very commonly used by both the Greeks and Romans for Apollo's role as the god of light. Like other Greek deities, he had a number of others applied to him, reflecting the variety of roles, duties, and aspects ascribed to the god.

Celtic epithets and cult titles
Apollo was worshipped throughout the Roman Empire. In the traditionally Celtic lands, he was most often seen as a healing and sun god. He was often equated with Celtic gods of similar character.Miranda J. Green, Dictionary of Celtic Myth and Legend, Thames and Hudson Ltd, 1997
 Apollo Atepomarus ("the great horseman" or "possessing a great horse"). Apollo was worshipped at Mauvières (Indre). Horses were, in the Celtic world, closely linked to the Sun.Corpus Inscriptionum Latinarum XIII, 1863–1986; A. Ross, Pagan Celtic Britain, 1967; M.J. Green, The Gods of the Celts, 1986, London
 Apollo Belenus ("bright" or "brilliant"). This epithet was given to Apollo in parts of Gaul, Northern Italy and Noricum (part of modern Austria). Apollo Belenus was a healing and sun god.J. Zwicker, Fontes Historiae Religionis Celticae, 1934–36, Berlin; Corpus Inscriptionum Latinarum V, XI, XII, XIII; J. Gourcest, "Le culte de Belenos en Provence occidentale et en Gaule", Ogam 6.6 (1954:257–262); E.

Origins
thumb|250px|The Omphalos in the Museum of Delphi
Apollo is considered the most Hellenic (Greek) of the Olympian gods.Burkert 1985:143.

The cult centers of Apollo in Greece, Delphi and Delos, date from the 8th century BCE. The Delos sanctuary was primarily dedicated to Artemis, Apollo's twin sister. At Delphi, Apollo was venerated as the slayer of the monstrous serpent Python. For the Greeks, Apollo was the most Greek of all the gods, and through the centuries he acquired different functions. In Archaic Greece he was the prophet, the oracular god who in older times was connected with "healing". In Classical Greece he was the god of light and of music, but in popular religion he had a strong function to keep away evil.Martin Nilsson (1967). "Die Geschicte der Giechischen Religion, Vol I." C.F.Beck Verlag.Munchen. p. 529 Walter Burkert discerned three components in the prehistory of Apollo worship, which he termed "a Dorian-northwest Greek component, a Cretan-Minoan component, and a Syro-Hittite component."Burkert, Walter. Greek Religion, 1985:144.

Healer and god-protector from evil
left|thumb|upright=.9|Apollo Victorious over the Python by Pietro Francavilla (1591) depicting Apollo's victory over the serpent Python (The Walters Art Museum).
In classical times, his major function in popular religion was to keep away evil, and he was therefore called "apotropaios" (, "averting evil") and "alexikakos" ( "keeping off ill"; from v.  + n. ).Pausanias VIII 41, 8-IV 34, 7-Sittig. Nom P. 48. f-Aristoph. Vesp. V. 61-Paus. I 3, 4. Martin Nilsson (1967) Vol I, pp. 540, 544 Apollo also had many epithets relating to his function as a healer. Some commonly-used examples are "paion" ( literally "healer" or "helper"): Harper's Dictionary of classical antiquity "epikourios" (, "succouring"), "oulios" (, "healer, baleful"). and "loimios" (, "of the plague"). In later writers, the word, "paion", usually spelled "Paean", becomes a mere epithet of Apollo in his capacity as a god of healing.

Apollo in his aspect of "healer" has a connection to the primitive god Paean (), who did not have a cult of his own. Paean serves as the healer of the gods in the Iliad, and seems to have originated in a pre-Greek religion.Paieon () puts pain-relieving medicines on the wounds of Pluton and Ares ( Ilias E401). This art is related with Egypt: (Odyssey D232): M. Nilsson Vol I, p. 543 It is suggested, though unconfirmed, that he is connected to the Mycenaean figure pa-ja-wo-ne (Linear B: ). At Google Books. Paean was the personification of holy songs sung by "seer-doctors" (), which were supposed to cure disease.. Which is sung to stop the plagues and the diseases. Proklos: Chrestom from Photios Bibl. code. 239, p. 321: Martin Nilsson. Die Geschicthe der Griechischen religion. Vol I, p. 543

Homer illustrated Paeon the god and the song both of apotropaic thanksgiving or triumph. Such songs were originally addressed to Apollo and afterwards to other gods: to Dionysus, to Apollo Helios, to Apollo's son Asclepius the healer. About the 4th century BCE, the paean became merely a formula of adulation; its object was either to implore protection against disease and misfortune or to offer thanks after such protection had been rendered. It was in this way that Apollo had become recognized as the god of music. Apollo's role as the slayer of the Python led to his association with battle and victory; hence it became the Roman custom for a paean to be sung by an army on the march and before entering into battle, when a fleet left the harbour, and also after a victory had been won.

In the Iliad, Apollo is the healer under the gods, but he is also the bringer of disease and death with his arrows, similar to the function of the Vedic god of disease Rudra."The conception that the diseases come from invisible shots sent by magicians or supernatural beings is common in primitive people and also in European folklore. In North-Europe they speak of the "Elf-shots". In Sweden where the Lapps were called magicians, they speak of the "Lappen-shots". Martin Nilsson (1967). Vol I, p. 541 He sends a plague () to the Achaeans. Knowing that Apollo can prevent a recurrence of the plague he sent, they purify themselves in a ritual and offer him a large sacrifice of cows, called a hecatomb.Ilias A 314. Martin Nilsson (1967). Vol I, p. 543

Dorian origin
The Homeric Hymn to Apollo depicts Apollo as an intruder from the north.Herbert W. Park (1956). The delphic oracle. Vol. I, p. 3 The connection with the northern-dwelling Dorians and their initiation festival apellai is reinforced by the month Apellaios in northwest Greek calendars.Graf, Apollo, pp. 104–113; Burkert also notes in this context Archilochus Fr. 94. The family-festival was dedicated to Apollo (Doric: ).Burkert, p. 255. Apellaios is the month of these rites, and Apellon is the "megistos kouros" (the great Kouros).Jane Ellen Harrison (2010): Themis: A study to the Social origins of Greek Religion. Cambridge University Press. p. 441.  However it can explain only the Doric type of the name, which is connected with the Ancient Macedonian word "pella" (Pella), stone. Stones played an important part in the cult of the god, especially in the oracular shrine of Delphi (Omphalos).Compare: Baetylus. In Semitic: sacred stoneMartin Nilsson (1967). Vol I. p. 556

Minoan origin
thumb|250px|Ornamented golden Minoan labrys
George Huxley regarded the identification of Apollo with the Minoan deity Paiawon, worshipped in Crete, to have originated at Delphi. In the Homeric Hymn, Apollo appeared as a dolphin and carried Cretan priests to Delphi, where they evidently transferred their religious practices. Apollo Delphinios or Delphidios was a sea-god especially worshipped in Crete and in the islands.Martin Nilsson (1967). Vol I, p. 554 A4 Apollo's sister Artemis, who was the Greek goddess of hunting, is identified with Britomartis (Diktynna), the Minoan "Mistress of the animals". In her earliest depictions she was accompanied by the "Master of the animals", a bow-wielding god of hunting whose name has been lost; aspects of this figure may have been absorbed into the more popular Apollo.Martin Nilsson (1967), Vol I, pp. 499–500

Anatolian origin
thumb|250px|Illustration of a coin of Apollo Agyieus from Ambracia
A non-Greek origin of Apollo has long been assumed in scholarship. The name of Apollo's mother Leto has Lydian origin, and she was worshipped on the coasts of Asia Minor. The inspiration oracular cult was probably introduced into Greece from Anatolia, which is the origin of Sibyl, and where some of the oldest oracular shrines originated. Omens, symbols, purifications, and exorcisms appear in old Assyro-Babylonian texts. These rituals were spread into the empire of the Hittites, and from there into Greece.Martin Nilsson. Die Geschichte der Griechische Religion Vol I, pp. 563–564

Homer pictures Apollo on the side of the Trojans, fighting against the Achaeans, during the Trojan War. He is pictured as a terrible god, less trusted by the Greeks than other gods. The god seems to be related to Appaliunas, a tutelary god of Wilusa (Troy) in Asia Minor, but the word is not complete.Paul Kretschmer (1936). Glotta XXIV p. 250. Martin Nilsson (1967). Vol I, p. 559. The stones found in front of the gates of Homeric Troy were the symbols of Apollo. A western Anatolian origin may also be bolstered by references to the parallel worship of Artimus (Artemis) and Qλdãns, whose name may be cognate with the Hittite and Doric forms, in surviving Lydian texts. However, recent scholars have cast doubt on the identification of Qλdãns with Apollo.

The Greeks gave to him the name  agyieus as the protector god of public places and houses who wards off evil and his symbol was a tapered stone or column.Martin Nilsson, Die Geschichte der Griechische Religion. vol. I (C. H. Beck), 1955:563f. However, while usually Greek festivals were celebrated at the full moon, all the feasts of Apollo were celebrated on the seventh day of the month, and the emphasis given to that day (sibutu) indicates a Babylonian origin.Martin Nilsson (1967). Vol I, p. 561.

The Late Bronze Age (from 1700 to 1200 BCE) Hittite and Hurrian Aplu was a god of plague, invoked during plague years. Here we have an apotropaic situation, where a god originally bringing the plague was invoked to end it. Aplu, meaning the son of, was a title given to the god Nergal, who was linked to the Babylonian god of the sun Shamash.de Grummond, Nancy Thomson (2006) Etruscan Myth, Sacred History, and Legend. (Philadelphia, Pennsylvania: University of Pennsylvania Museum of Archaeology and Anthropology); Mackenzie, Donald A. (2005) Myths of Babylonia and Assyria (Gutenberg) Homer interprets Apollo as a terrible god () who brings death and disease with his arrows, but who can also heal, possessing a magic art that separates him from the other Greek gods.Martin Nilsson (1967). Vol I. pp. 559–560. In Iliad, his priest prays to Apollo Smintheus,"You Apollo Smintheus, let my tears become your arrows against the Danaans, for revenge". Iliad 1.33 (A 33). the mouse god who retains an older agricultural function as the protector from field rats.An ancient aetiological myth connects sminthos with mouse and suggests Cretan origin. Apollo is the mouse-god (Strabo 13.1.48)."Sminthia" in several areas of Greece. In Rhodes (Lindos) they belong to Apollo and Dionysos who have destroyed the rats that were swallowing the grapes". Martin Nilsson (1967). pp. 534–535. All these functions, including the function of the healer-god Paean, who seems to have Mycenean origin, are fused in the cult of Apollo.

 Proto-Indo-European 

The Vedic Rudra has some similar functions to Apollo. The terrible god is called "the archer" and the bow is also an attribute of Shiva.For  as a name of Shiva see: Apte, p. 910. Rudra could bring diseases with his arrows, but he was able to free people of them and his alternative Shiva is a healer physician god.For the association between Rudra and disease, with Rigvedic references, see: Bhandarkar, p. 146. However the Indo-European component of Apollo does not explain his strong relation with omens, exorcisms, and with the oracular cult.

Oracular cult
thumb|250px|Columns of the Temple of Apollo at Delphi, Greece

Unusually among the Olympic deities, Apollo had two cult sites that had widespread influence: Delos and Delphi. In cult practice, Delian Apollo and Pythian Apollo (the Apollo of Delphi) were so distinct that they might both have shrines in the same locality. Lycia was sacred to the god, for this Apollo was also called Lycian.Diodorus Siculus, Library 1-7, 5.77.5Diodorus Siculus, Library 1-7, 5.77.5 - GR Apollo's cult was already fully established when written sources commenced, about 650 BCE. Apollo became extremely important to the Greek world as an oracular deity in the archaic period, and the frequency of theophoric names such as Apollodorus or Apollonios and cities named Apollonia testify to his popularity. Oracular sanctuaries to Apollo were established in other sites. In the 2nd and 3rd century CE, those at Didyma and Claros pronounced the so-called "theological oracles", in which Apollo confirms that all deities are aspects or servants of an all-encompassing, highest deity. "In the 3rd century, Apollo fell silent. Julian the Apostate (359–361) tried to revive the Delphic oracle, but failed."

Oracular shrines
thumb|250px|Delos lions
Apollo had a famous oracle in Delphi, and other notable ones in Claros and Didyma. His oracular shrine in Abae in Phocis, where he bore the toponymic epithet Abaeus (, Apollon Abaios), was important enough to be consulted by Croesus.Herodotus, 1.46.
His oracular shrines include:

 Abae in Phocis.
 Bassae in the Peloponnese.
 At Clarus, on the west coast of Asia Minor; as at Delphi a holy spring which gave off a pneuma, from which the priests drank.
 In Corinth, the Oracle of Corinth came from the town of Tenea, from prisoners supposedly taken in the Trojan War.
 At Khyrse, in Troad, the temple was built for Apollo Smintheus.
 In Delos, there was an oracle to the Delian Apollo, during summer. The Hieron (Sanctuary) of Apollo adjacent to the Sacred Lake, was the place where the god was said to have been born.
 In Delphi, the Pythia became filled with the pneuma of Apollo, said to come from a spring inside the Adyton.
 In Didyma, an oracle on the coast of Anatolia, south west of Lydian (Luwian) Sardis, in which priests from the lineage of the Branchidae received inspiration by drinking from a healing spring located in the temple. Was believed to have been founded by Branchus, son or lover of Apollo.
 In Hierapolis Bambyce, Syria (modern Manbij), according to the treatise De Dea Syria, the sanctuary of the Syrian Goddess contained a robed and bearded image of Apollo. Divination was based on spontaneous movements of this image.Lucian (attrib.), De Dea Syria 35–37.
 At Patara, in Lycia, there was a seasonal winter oracle of Apollo, said to have been the place where the god went from Delos. As at Delphi the oracle at Patara was a woman.
 In Segesta in Sicily.

Oracles were also given by sons of Apollo.
 In Oropus, north of Athens, the oracle Amphiaraus, was said to be the son of Apollo; Oropus also had a sacred spring.
 in Labadea,  east of Delphi, Trophonius, another son of Apollo, killed his brother and fled to the cave where he was also afterwards consulted as an oracle.

Temples of Apollo

Many temples were dedicated to Apollo in Greece and the Greek colonies. They show the spread of the cult of Apollo and the evolution of Greek architecture, which was mostly based on the rightness of form and on mathematical relations. Some of the earliest temples, especially in Crete, do not belong to any Greek order. It seems that the first peripteral temples were rectangular wooden structures. The different wooden elements were considered divine, and their forms were preserved in the marble or stone elements of the temples of Doric order. The Greeks used standard types because they believed that the world of objects was a series of typical forms which could be represented in several instances. The temples should be canonic, and the architects were trying to achieve this esthetic perfection.To know what a thing is, we must know the look of it": Rhys Carpenter: The esthetic basis of Greek art. Indiana University Press. p. 108 From the earliest times there were certain rules strictly observed in rectangular peripteral and prostyle buildings. The first buildings were built narrowly in order to hold the roof, and when the dimensions changed some mathematical relations became necessary in order to keep the original forms. This probably influenced the theory of numbers of Pythagoras, who believed that behind the appearance of things there was the permanent principle of mathematics.C. M. Bowra (1957). The Greek experience, p. 166.

The Doric order dominated during the 6th and the 5th century BC but there was a mathematical problem regarding the position of the triglyphs, which couldn't be solved without changing the original forms. The order was almost abandoned for the Ionic order, but the Ionic capital also posed an insoluble problem at the corner of a temple. Both orders were abandoned for the Corinthian order gradually during the Hellenistic age and under Rome.

The most important temples are:

Eretria: According to the Homeric hymn to Apollo, the god arrived on the plain, seeking for a location to establish its oracle. The first temple of Apollo Daphnephoros, "Apollo, laurel-bearer", or "carrying off Daphne", is dated to 800 B.C. The temple was curvilinear hecatombedon (a hundred feet). In a smaller building were kept the bases of the laurel branches which were used for the first building. Another temple probably peripteral was built in the 7th century B.C., with an inner row of wooden columns over its Geometric predecessor. It was rebuilt peripteral around 510 B.C., with the stylobate measuring 21,00 x 43,00 m. The number of pteron column was 6 x 14.Hellenic Ministry of culture, Temple of Apollo Daphnephoros Rufus B.

Mythology

In the myths, Apollo is the son of Zeus, the king of the gods, and Leto, his previous wifeHomer, Iliad 21.499 or one of his mistresses. Apollo often appears in the myths, plays and hymns either directly or indirectly through his oracles. As Zeus' favorite son, he had direct access to the mind of Zeus and was willing to reveal this knowledge to humans. A divinity beyond human comprehension, he appears both as a beneficial and a wrathful god.

Birth
thumb|Leto with her children, by William Henry Rinehart

Homeric Hymn to Apollo

Pregnant with the offsprings of Zeus, Leto wandered through many lands wanting to give birth to Apollo. However all the lands rejected her out of fear. Upon reaching Delos, Leto requested the island to shelter her, and that in return her son would bring fame and prosperity to the island. Delos then revealed to Leto that Apollo was rumoured to be the god who will "greatly lord it among gods and men all over the fruitful earth". For this reason, all the lands were fearful and Delos feared that Apollo would cast her aside once he is be born. Hearing this, Leto swore on the river Styx that if she is allowed to give birth on the island, her son would honour Delos the most amongst all the other lands. Assured by this, Delos agreed to assist Leto. All goddesses except Hera also then came to aid Leto. 

However, Hera had tricked Eileithyia, the goddess of childbirth, to stay on Olympus, due to which Leto was unable to give birth. The goddesses then convinced Iris to go bring Eileithyia by offering her a necklace of amber 9 yards (8.2 m) long. Iris did accordingly and persuaded Eilithyia to step onto the island. Thus, clutching a palm tree, Leto finally gave birth after labouring for nine days and nine nights, with Apollo "leaping forth" from his mother's womb. The goddesses washed the new born, covered him in a white garment and fastened golden bands around him. As Leto was unable to feed him, Themis, the goddess of divine law, fed him nectar and ambrosia. Upon tasting the divine food, the child broke free of the bands fastened onto him and declared that he would be the master of lyre and archery, and interpret the will of Zeus to humankind. He then started to walk, which caused the island to be filled with gold."Homeric hymn to Delian Apollo"

Callimachus' hymn to Delos 

The island Delos used to be a woman named Asteria, who jumped into the waters to escape the advances of Zeus and became a free floating island of the same name. When Leto got pregnant, Hera was told that Leto will give birth to a son who would become to Zeus more dearer than Ares. Enraged by this, Hera watched over the heavens and sent out Ares and Iris to prevent Leto from giving birth on the earth. Ares stationed over the mainland and Iris over the islands, they both threatened all the lands and prevented them from helping Leto. 

When Leto arrived to Thebes, fetal Apollo prophesied from his mother's womb that in the future, he would punish a slanderous woman in Thebes (Niobe), and so he did not want to be born there. Leto then went to Thessaly and sought out the help of the river nymphs whose father was the river Peneus. Though he was initially fearful and reluctant, Peneus later decided to let Leto give birth in his waters. He did not change his mind even when Ares produced a terrifying sound and threatened to hurl mountain peaks into the river. But in the end, Leto declined his help as she did not want him to suffer for her sake. 

After being turned away from various lands, Apollo spoke again from the womb, asking Leto to take look at the floating island in front of her and expressing his wish to be born there. When Leto approached Asteria, all the other islands fled. But Asteria welcomed Leto without any fear of Hera. Walking on the island, she sat down against a palm tree and asked Apollo to be born. During the child birth, the swans circled the island seven times, due to which later on Apollo would play the seven stringed lyre. When Apollo finally "leapt forth" from his mother's womb, the nymphs of the island sung a hymn to Eilithyia that was heard to the heavens. The moment Apollo was born, the entire island, including the trees and the waters, became gold. Asteria bathed the new born, swaddled him and fed him with her breast milk. Since then, the island got rooted and was called as Delos.

Hera was no more angry as Zeus had managed to calm her down, and she held no grudge against Asteria due to the fact that Asteria had rejected Zeus in the past. 
"Callimachus, Hymn to Delos"

Pindar's fragments

Pindar is the earliest source who explicitly calls Apollo and Artemis as twins. Here, Asteria is also stated to be Leto's sister. Wanting escape Zeus' advances, she flung herself into the sea and became a floating rock called Ortygia until the twins were born.Pindar, Pa. VII b When Leto stepped on the rock, four pillars with adamantine bases rose from the earth and held up the rock.Pindar, Processional Song on Delos When Apollo and Artemis were born, their bodies shone radiantly and a chant was sung by Eileithyia and Lachesis, one of the  three Moirai.Pindar, Pa. XII

Pseudo-Hyginus

Scorning the advances of Zeus, Asteria tranformed herself into a bird and jumped into a sea. From her, an island rose which was called Ortygia.Pseudo-Hyginus, Fabulae 53 
When Hera discovered that Leto was pregnant with Zeus' child, she decreed that Leto can give birth only in a place where sun does not shine. During this time, the monster Python also started hounding Leto with an intent of killing her, because he had foreseen his death coming at the hands of Leto's offspring. However, on Zeus' orders, Boreas carried away Leto and entrusted her to Poseidon. To protect her, Poseidon took her to the island Ortygia and covered it with waves so that the sun would not shine on it. Leto gave birth clinging to an olive tree and henceforth the island was called Delos.Pseudo-Hyginus, Fabulae 140

thumb|Leto with Apollo and Artemis, by Francesco Pozzi

Other variations of Apollo's birth include:

Aelian states that it took Leto twelve days and twelve nights to travel from Hyperborea to Delos.Aelian, Characteristics of Animals 4. 4 Leto changed herself into a she-wolf before giving birth. This is given as the reason why Homer describes Apollo as the "wolf-born god".Aelian, Characteristics of Animals 10. 26Homer, Iliad 

Libanius wrote that neither land nor visible islands would receive Leto, but by the will of Zeus Delos then became visible, and thus received Leto and the children.Libanius, Progymnasmata 2.25

According to Strabo, the Curetes helped Leto by creating loud noises with their weapons and thus frightening Hera, they concealed Leto's childbirth.Strabo, Geography 14. 1. 20

Theognis wrote that the island was filled with ambrosial fragrance when Apollo was born, and the Earth laughed with joy.Theognis, Fragment 1. 5 

While in some accounts Apollo's birth itself fixed the floating Delos to the earth, there are accounts of Apollo securing Delos to the bottom of the ocean a little while later.Virgil, Aeneid, 3.80Nonnus, Dionysiaca 
This island became sacred to Apollo and was one of the major cult centres of the god.
Apollo was born on the seventh day (, hebdomagenes). of the month Thargelion—according to Delian tradition—or of the month Bysios—according to Delphian tradition. The seventh and twentieth, the days of the new and full moon, were ever afterwards held sacred to him.

The general consensus is that Artemis was born first and subsequently assisted with the birth of Apollo.Servius, Commentary on Virgil's Aeneid 3.7Orphic Hymn 35 to Leto, 3–5

Hyperborea

Hyperborea, the mystical land of eternal spring, venerated Apollo above all the gods. The Hyperboreans always sang and danced in his honor and hosted Pythian games.Pindar, Pindar, Olympian Ode There, a vast forest of beautiful trees was called "the garden of Apollo". Apollo spent the winter months among the Hyperboreans,Apollonius Rhodius, Argonautica, 2. 674. leaving his shrine in Delphi under the care of Dionysus. His absence from the world caused coldness and this was marked as his annual death. No prophecies were issued during this time.Joseph Eddy Fontenrose, Python: A Study of Delphic Myth and Its Origins He returned to the world during the beginning of the spring. The Theophania festival was held in Delphi to celebrate his return.Plutarch, de his qui sero a num. pun. p. 557F

However, Diodorus Silculus states that Apollo visited Hyperborea every nineteen years. This nineteen-year period was called by the Greeks as the ‘year of Meton', the time period in which the stars returned to their initial positions. And that visiting Hyperborea at that time, Apollo played on the cithara and danced continuously from the vernal equinox until the rising of the Pleiades (constellations).Diodorus Siculus, Library of History 2. 47. 1 - 6

Hyperborea was also Leto's birthplace. It is said that Leto came to Delos from Hyperborea accompanied by a pack of wolves. Henceforth, Hyperborea became Apollo's winter home and wolves became sacred to him. His intimate connection to wolves is evident from his epithet Lyceus, meaning wolf-like. But Apollo was also the wolf-slayer in his role as the god who protected flocks from predators. The Hyperborean worship of Apollo bears the strongest marks of Apollo being worshipped as the sun god. Shamanistic elements in Apollo's cult are often liked to his Hyperborean origin, and he is likewise speculated to have originated as a solar shaman.Anna Afonasina, Shamanism and the Orphic traditionFritz Graf, Apollo Shamans like Abaris and Aristeas were also the followers of Apollo, who hailed from Hyperborea.

In myths, the tears of amber Apollo shed when his son Asclepius died mixed with the waters of the river Eridanos, which surrounded Hyperborea. Apollo also buried in Hyperborea the arrow which he had used to kill the Cyclopes. He later gave this arrow to Abaris.Apollonius Rhodius, Argonautica, 4. 594.

Childhood and youth

Growing up, Apollo was nursed by the nymphs Korythalia and Aletheia, the personification of truth.Plutarch, Moralia 657e As a child, Apollo is said to have built a foundation and an altar on Delos using the horns of the goats that his sister Artemis hunted. Since he learnt the art of building when young, he later came to be known as Archegetes, the founder (of towns) and a god who guided men to build new cities. From his father Zeus, Apollo had also received a golden chariot drawn by swans.Timothy P. Bridgman, Hyperboreans: Myth and History in Celtic-Hellenic Contacts

thumb|Phoebe gifts the oracular tripod to Apollo, by John Flaxman

In his early years when Apollo spent his time herding cows, he was reared by Thriae, the bee nymphs, who trained him and enhanced his prophetic skills.Homeric Hymn 4 to Hermes 550. Apollo is also said to have invented the lyre, and along with Artemis, the art of archery. He then taught the humans the art of healing and archery.Diodorus Siculus, 5.74.5. Phoebe, his grandmother, gave the oracular shrine of Delphi to Apollo as a birthday gift. Themis inspired him to be the oracular voice of Delphi thereon.Aeschylus, Eumenides 1; Orphic Hymn 79 to Themis (Athanassakis and Wolkow, p. 62).

Python
thumb|190px|Apollo victorious over the Python, by François Gaspard Adam|left
thumb|Python pursuing Leto and her children, engravings on wood

Python, a chthonic serpent-dragon, was a child of Gaia and the guardian of the Delphic Oracle, whose death was foretold by Apollo when he was still in Leto's womb. Python was the nurse of the giant Typhon.Homeric hymn to Apollo In most of the traditions, Apollo was still a child when he killed Python.

Python was sent by Hera to hunt the pregnant Leto to death, and assaulted her. To avenge the trouble given to his mother, Apollo went in search of Python and killed it in the sacred cave at Delphi with the bow and arrows that he had received from Hephaestus. The Delphian nymphs who were present encouraged Apollo during the battle with the cry "Hie Paean". After Apollo was victorious, they also brought him gifts and gave the Corycian cave to him.Children of the Gods by Kenneth McLeish, p. 32. According to Homer, Apollo encountered and killed the Python when he was looking for a place to establish his shrine.

According to another version, when Leto was in Delphi, Python attacked her. Apollo defended his mother and killed Python.Euripides Iphigenia in Tauris Euripides in his Iphigenia in Aulis gives an account of his fight with Python and the event's aftermath. 

A detailed account of Apollo's conflict with Gaia and Zeus' intervention on behalf of his young son is also given. 

Apollo also demanded that all other methods of divination be made inferior to his, a wish that Zeus granted him readily. Because of this, Athena, who had been practicing divination by throwing pebbles, cast her pebbles away in displeasure.John Opsopaus, The Oracles of Apollo: Practical Ancient Greek Divination for Today

However, Apollo had committed a blood murder and had to be purified. Because Python was a child of Gaia, Gaia wanted Apollo to be banished to Tartarus as a punishment.Pindar's Paeans: A Reading of the Fragments with a Survey of the Genre Zeus didn't agree and instead exiled his son from Olympus, and instructed him to get purified. Apollo had to serve as a slave for nine years.John Lemprière, Bibliotheca Classica After the servitude was over, as per his father's order, he travelled to the Vale of Tempe to bathe in waters of Peneus.The Uses of Greek Mythology By Ken Dowden There Zeus himself performed purificatory rites on Apollo. Purified, Apollo was escorted by his half-sister Athena to Delphi where the oracular shrine was finally handed over to him by Gaia.Aristonous: Paean To Apollo According to a variation, Apollo had also travelled to Crete, where Carmanor purified him. Apollo later established the Pythian games to appropriate Gaia. Henceforth, Apollo became the god who cleansed himself from the sin of murder, made men aware of their guilt and purified them.Apollo, Fritz Graf

Soon after, Zeus instructed Apollo to go to Delphi and establish his law. But Apollo, disobeying his father, went to the land of Hyperborea and stayed there for a year. He returned only after the Delphians sang hymns to him and pleaded with him to come back. Zeus, pleased with his son's integrity, gave Apollo the seat next to him on his right side. He also gave Apollo various gifts, like a golden tripod, a golden bow and arrows, a golden chariot and the city of Delphi.Benjamin Acosta-Hughes, Luigi Lehnus, Susan Stephens - Brill's Companion to Callimachus

Soon after his return, Apollo needed to recruit people to Delphi. So, when he spotted a ship sailing from Crete, he sprang aboard in the form of a dolphin. The crew was awed into submission and followed a course that led the ship to Delphi. There Apollo revealed himself as a god. Initiating them to his service, he instructed them to keep righteousness in their hearts. The Pythia was Apollo's high priestess and his mouthpiece through whom he gave prophecies. Pythia is arguably the constant favorite of Apollo among the mortals.

Tityos
thumb|Apollo slaying Tityos, Attic red-figure kylix, 460–450 BC

Hera once again sent another giant, Tityos to rape Leto. This time Apollo shot him with his arrows and attacked him with his golden sword. According to another version, Artemis also aided him in protecting their mother by attacking Tityos with her arrows.Scholia on Pindar, Pythian Odes 4.160 citing Pherecydes After the battle Zeus finally relented his aid and hurled Tityos down to Tartarus. There, he was pegged to the rock floor, covering an area of , where a pair of vultures feasted daily on his liver.

Admetus
thumb|Apollo Guards the Herds (or Flocks) of King Admetus, by Felice Gianni

Admetus was the king of Pherae, who was known for his hospitality. When Apollo was exiled from Olympus for killing Python, he served as a herdsman under Admetus, who was then young and unmarried. Apollo is said to have shared a romantic relationship with Admetus during his stay.Callimachus, Hymn II to Apollo. After completing his years of servitude, Apollo went back to Olympus as a god.

Because Admetus had treated Apollo well, the god conferred great benefits on him in return. Apollo's mere presence is said to have made the cattle give birth to twins. Apollo helped Admetus win the hand of Alcestis, the daughter of King Pelias,Apollodorus, 1.9.15.Hyginus, Fabulae 50-51. by taming a lion and a boar to draw Admetus' chariot. He was present during their wedding to give his blessings. When Admetus angered the goddess Artemis by forgetting to give her the due offerings, Apollo came to the rescue and calmed his sister. When Apollo learnt of Admetus' untimely death, he convinced or tricked the Fates into letting Admetus live past his time.

According to another version, or perhaps some years later, when Zeus struck down Apollo's son Asclepius with a lightning bolt for resurrecting the dead, Apollo in revenge killed the Cyclopes, who had fashioned the bolt for Zeus.Apollodorus, 3.10.4. Apollo would have been banished to Tartarus for this, but his mother Leto intervened, and reminding Zeus of their old love, pleaded with him not to kill their son. Zeus obliged and sentenced Apollo to one year of hard labor once again under Admetus.

The love between Apollo and Admetus was a favored topic of Roman poets like Ovid and Servius.

Niobe
thumb|286x286px|Niobe's children are killed by Apollo and Diana by Pierre-Charles Jombert

The fate of Niobe was prophesied by Apollo while he was still in Leto's womb. Niobe was the queen of Thebes and wife of Amphion. She displayed hubris when she boasted that she was superior to Leto because she had fourteen children (Niobids), seven male and seven female, while Leto had only two. She further mocked Apollo's effeminate appearance and Artemis' manly appearance. Leto, insulted by this, told her children to punish Niobe. Accordingly, Apollo killed Niobe's sons, and Artemis her daughters. According to some versions of the myth, among the Niobids, Chloris and her brother Amyclas were not killed because they prayed to Leto. Amphion, at the sight of his dead sons, either killed himself or was killed by Apollo after swearing revenge.

A devastated Niobe fled to Mount Sipylos in Asia Minor and turned into stone as she wept. Her tears formed the river Achelous. Zeus had turned all the people of Thebes to stone and so no one buried the Niobids until the ninth day after their death, when the gods themselves entombed them.

When Chloris married and had children, Apollo granted her son Nestor the years he had taken away from the Niobids. Hence, Nestor was able to live for 3 generations.Hyginus, Fabulae 10

Building the walls of Troy 

thumb|160px|left|Laomedon Refusing Payment to Poseidon and Apollo, by Joachim von Sandrart

Once Apollo and Poseidon served under the Trojan king Laomedon in accordance with Zeus' words. Apollodorus states that the gods willingly went to the king disguised as humans in order to check his hubris.Apollodorus, Bibliotheca 2.5 Apollo guarded the cattle of Laomedon in the valleys of Mount Ida, while Poseidon built the walls of Troy.Homer, The Iliad 21.434 Other versions make both Apollo and Poseidon the builders of the wall. In Ovid's account, Apollo completes his task by playing his tunes on his lyre.

In Pindar's odes, the gods took a mortal named Aeacus as their assistant.Pindar, Olympian Odes viii. 39, &c. When the work was completed, three snakes rushed against the wall, and though the two that attacked the sections of the wall built by the gods fell down dead, the third forced its way into the city through the portion of the wall built by Aeacus. Apollo immediately prophesied that Troy would fall at the hands of Aeacus's descendants, the Aeacidae (i.e. his son Telamon joined Heracles when he sieged the city during Laomedon's rule. Later, his great-grandson Neoptolemus was present in the wooden horse that leads to the downfall of Troy).

However, the king not only refused to give the gods the wages he had promised, but also threatened to bind their feet and hands, and sell them as slaves. Angered by the unpaid labour and the insults, Apollo infected the city with a pestilence and Poseidon sent the sea monster Cetus. To deliver the city from it, Laomedon had to sacrifice his daughter Hesione (who would later be saved by Heracles).

During his stay in Troy, Apollo had a lover named Ourea, who was a nymph and daughter of Poseidon. Together they had a son named Ileus, whom Apollo loved dearly.Hesiod, Catalogues of Women Fragment 83

Trojan War

Apollo sided with the Trojans during the Trojan War waged by the Greeks against the Trojans.

During the war, the Greek king Agamemnon captured Chryseis, the daughter of Apollo's priest Chryses, and refused to return her. Angered by this, Apollo shot arrows infected with the plague into the Greek encampment. He demanded that they return the girl, and the Achaeans (Greeks) complied, indirectly causing the anger of Achilles, which is the theme of the Iliad.

thumb|left|Apollo preceding Hector with his Aegis, and dispersing the Greeks, by John Flaxman

Receiving the aegis from Zeus, Apollo entered the battlefield as per his father's command, causing great terror to the enemy with his war cry. He pushed the Greeks back and destroyed many of the soldiers. He is described as "the rouser of armies" because he rallied the Trojan army when they were falling apart.

When Zeus allowed the other gods to get involved in the war, Apollo was provoked by Poseidon to a duel. However, Apollo declined to fight him, saying that he would not fight his uncle for the sake of mortals.

thumb|Apollo prevents Diomedes from pursuing Aeneas

When the Greek hero Diomedes injured the Trojan hero Aeneas, Aphrodite tried to rescue him, but Diomedes injured her as well. Apollo then enveloped Aeneas in a cloud to protect him. He repelled the attacks Diomedes made on him and gave the hero a stern warning to abstain from attacking a god. Aeneas was then taken to Pergamos, a sacred spot in Troy, where he was healed.

After the death of Sarpedon, a son of Zeus, Apollo rescued the corpse from the battlefield as per his father's wish and cleaned it. He then gave it to Sleep (Hypnos) and Death (Thanatos). Apollo had also once convinced Athena to stop the war for that day, so that the warriors can relieve themselves for a while.

thumb|Apollo protecting Hector's body, by John Flaxman

The Trojan hero Hector (who, according to some, was the god's own son by HecubaStesichorus, Fr. 108; Tzetzes, On Lycophron  266; Porphyry in his Omissions states that Ibycus, Alexander, Euphorion and Lycophron all made Hector the son of Apollo.) was favored by Apollo. When he got severely injured, Apollo healed him and encouraged him to take up his arms. During a duel with Achilles, when Hector was about to lose, Apollo hid Hector in a cloud of mist to save him. When the Greek warrior Patroclus tried to get into the fort of Troy, he was stopped by Apollo. Encouraging Hector to attack Patroclus, Apollo stripped the armour of the Greek warrior and broke his weapons. Patroclus was eventually killed by Hector. At last, after Hector's fated death, Apollo protected his corpse from Achilles' attempt to mutilate it by creating a magical cloud over the corpse, shielding it from the rays of the sun.

Apollo held a grudge against Achilles throughout the war because Achilles had murdered his son Tenes before the war began and brutally assassinated his son Troilus in his own temple. Not only did Apollo save Hector from Achilles, he also tricked Achilles by disguising himself as a Trojan warrior and driving him away from the gates. He foiled Achilles' attempt to mutilate Hector's dead body.

Finally, Apollo caused Achilles' death by guiding an arrow shot by Paris into Achilles' heel. In some versions, Apollo himself killed Achilles by taking the disguise of Paris.

Apollo helped many Trojan warriors, including Agenor, Polydamas, Glaucus in the battlefield. Though he greatly favored the Trojans, Apollo was bound to follow the orders of Zeus and served his father loyally during the war.

Nurturer of the young

Apollo Kourotrophos is the god who nurtures and protects children and the young, especially boys. He oversees their education and their passage into adulthood. Education is said to have originated from Apollo and the Muses. Many myths have him train his children. It was a custom for boys to cut and dedicate their long hair to Apollo after reaching adulthood.

Chiron, the abandoned centaur, was fostered by Apollo, who instructed him in medicine, prophecy, archery and more. Chiron would later become a great teacher himself.

Asclepius in his childhood gained much knowledge pertaining to medicinal arts from his father. However, he was later entrusted to Chiron for further education.

Anius, Apollo's son by Rhoeo, was abandoned by his mother soon after his birth. Apollo brought him up and educated him in mantic arts. Anius later became the priest of Apollo and the king of Delos.

Iamus was the son of Apollo and Evadne. When Evadne went into labour, Apollo sent the Moirai to assist his lover. After the child was born, Apollo sent snakes to feed the child some honey. When Iamus reached the age of education, Apollo took him to Olympia and taught him many arts, including the ability to understand and explain the languages of birds.Pindar, Olympian Ode 6

Idmon was educated by Apollo to be a seer. Even though he foresaw his death that would happen in his journey with the Argonauts, he embraced his destiny and died a brave death. To commemorate his son's bravery, Apollo commanded Boeotians to build a town around the tomb of the hero, and to honor him.Apollonius Rhodius. Argonautica ii, 846 ff

Apollo adopted Carnus, the abandoned son of Zeus and Europa. He reared the child with the help of his mother Leto and educated him to be a seer.

When his son Melaneus reached the age of marriage, Apollo asked the princess Stratonice to be his son's bride and carried her away from her home when she agreed.

Apollo saved a shepherd boy (name unknown) from death in a large deep cave, by means of vultures. To thank him, the shepherd built Apollo a temple under the name Vulturius.The Cyclopedia, Or, Universal Dictionary of Arts, Sciences, and Literature, Volume 37

God of music

thumb|220px|The music of the spheres. Shown in this engraving from Renaissance Italy are Apollo, the Muses, the planetary spheres and musical ratios.
left|thumb|Apollo, Hyacinth and Cyparissus singing and playing by Alexander Ivanov 1831–1834
Immediately after his birth, Apollo demanded a lyre and invented the paean, thus becoming the god of music. As the divine singer, he is the patron of poets, singers and musicians. The invention of string music is attributed to him. Plato said that the innate ability of humans to take delight in music, rhythm and harmony is the gift of Apollo and the Muses.Plato, Laws 653.4 According to Socrates, ancient Greeks believed that Apollo is the god who directs the harmony and makes all things move together, both for the gods and the humans. For this reason, he was called Homopolon before the Homo was replaced by A.The prefix A means "without" or "not", and polloi means "many", thus Apollo means "not many" or "united", referring to his ability to create harmony.Plato, Cratylus Apollo's harmonious music delivered people from their pain, and hence, like Dionysus, he is also called the liberator. The swans, which were considered to be the most musical among the birds, were believed to be the "singers of Apollo". They are Apollo's sacred birds and acted as his vehicle during his travel to Hyperborea. Aelian says that when the singers would sing hymns to Apollo, the swans would join the chant in unison.Aelian, On the nature of Animals 11. 1

thumb|270px|Apollo and the Muses on Parnassus, by Andrea Appiani|left

Among the Pythagoreans, the study of mathematics and music were connected to the worship of Apollo, their principal deity.Aelian, Varia Historia, 2. 26Diogenes Laërtius, 8.13Iamblichus, Vit. Pyth. 8.91.141 Their belief was that music purifies the soul, just as medicine purifies the body. They also believed that music was delegated to the same mathematical laws of harmony as the mechanics of the cosmos, evolving into an idea known as the music of the spheres.Landels, John G (1999) Music in Ancient Greece and Rome

Apollo appears as the companion of the Muses, and as Musagetes ("leader of Muses") he leads them in dance. They spend their time on Parnassus, which is one of their sacred places. Apollo is also the lover of the Muses and by them he became the father of famous musicians like Orpheus and Linus.

Apollo is often found delighting the immortal gods with his songs and music on the lyre.Iliad (i. 603) In his role as the god of banquets, he was always present to play music at weddings of the gods, like the marriage of Eros and Psyche, Peleus and Thetis. He is a frequent guest of the Bacchanalia, and many ancient ceramics depict him being at ease amidst the maenads and satyrs.Detienne, Marcel (2001) Forgetting Delphi between Apollo and Dionysus Apollo also participated in musical contests when challenged by others. He was the victor in all those contests, but he tended to punish his opponents severely for their hubris.

thumb|170px|Detail of Apollo's lyre|left

Apollo's lyre

The invention of the lyre is attributed either to Hermes or to Apollo himself. Distinctions have been made that Hermes invented lyre made of tortoise shell, whereas the lyre Apollo invented was a regular lyre.Diodorus Siculus

Myths tell that the infant Hermes stole a number of Apollo's cows and took them to a cave in the woods near Pylos, covering their tracks. In the cave, he found a tortoise and killed it, then removed the insides. He used one of the cow's intestines and the tortoise shell and made his lyre.

thumb|180px|The friendship of Apollo and Hermes, by Noël Coypel

Upon discovering the theft, Apollo confronted Hermes and asked him to return his cattle. When Hermes acted innocent, Apollo took the matter to Zeus. Zeus, having seen the events, sided with Apollo, and ordered Hermes to return the cattle.Hard, p. 162. Hermes then began to play music on the lyre he had invented. Apollo fell in love with the instrument and offered to exchange the cattle for the lyre. Hence, Apollo then became the master of the lyre.

According to other versions, Apollo had invented the lyre himself, whose strings he tore in repenting of the excess punishment he had given to Marsyas. Hermes' lyre, therefore, would be a reinvention.

Contest with Pan

thumb|The musical duel of Pan and Apollo, by Laurits Tuxen

Once Pan had the audacity to compare his music with that of Apollo and to challenge the god of music to a contest. The mountain-god Tmolus was chosen to umpire. Pan blew on his pipes, and with his rustic melody gave great satisfaction to himself and his faithful follower, Midas, who happened to be present. Then, Apollo struck the strings of his lyre. It was so beautiful that Tmolus at once awarded the victory to Apollo, and everyone was pleased with the judgement. Only Midas dissented and questioned the justice of the award. Apollo did not want to suffer such a depraved pair of ears any longer, and caused them to become the ears of a donkey.

Contest with Marsyas

Marsyas was a satyr who was punished by Apollo for his hubris. He had found an aulos on the ground, tossed away after being invented by Athena because it made her cheeks puffy. Athena had also placed a curse upon the instrument, that whoever would pick it up would be severely punished. When Marsyas played the flute, everyone became frenzied with joy. This led Marsyas to think that he was better than Apollo, and he challenged the god to a musical contest. The contest was judged by the Muses, or the nymphs of Nysa. Athena was also present to witness the contest.

Marsyas taunted Apollo for "wearing his hair long, for having a fair face and smooth body, for his skill in so many arts".Apuleius, Florida 3.2 He also further said,

The Muses and Athena sniggered at this comment. The contestants agreed to take turns displaying their skills and the rule was that the victor could "do whatever he wanted" to the loser.

thumb|260px|The contest between Apollo and Marsyas by Palma il Giovane|left

According to one account, after the first round, they both were deemed equal by the Nysiads. But in the next round, Apollo decided to play on his lyre and add his melodious voice to his performance. Marsyas argued against this, saying that Apollo would have an advantage and accused Apollo of cheating. But Apollo replied that since Marsyas played the flute, which needed air blown from the throat, it was similar to singing, and that either they both should get an equal chance to combine their skills or none of them should use their mouths at all. The nymphs decided that Apollo's argument was just. Apollo then played his lyre and sang at the same time, mesmerising the audience. Marsyas could not do this. Apollo was declared the winner and, angered with Marsyas' haughtiness and his accusations, decided to flay the satyr.Diodorus Siculus, Library of History 5. 75. 3

thumb|Marsyas Flayed by the Order of Apollo, by	Charles-André van Loo

According to another account, Marsyas played his flute out of tune at one point and accepted his defeat. Out of shame, he assigned to himself the punishment of being skinned for a wine sack.Philostratus the Younger, Imagines 2 (trans. Fairbanks) Another variation is that Apollo played his instrument upside down. Marsyas could not do this with his instrument. So the Muses who were the judges declared Apollo the winner. Apollo hung Marsyas from a tree to flay him.Man Myth and Magic by Richard Cavendish

Apollo flayed the limbs of Marsyas alive in a cave near Celaenae in Phrygia for his hubris to challenge a god. He then gave the rest of his body for proper burialHyginus, Fabulae 165. and nailed Marsyas' flayed skin to a nearby pine-tree as a lesson to the others. Marsyas' blood turned into the river Marsyas. But Apollo soon repented and being distressed at what he had done, he tore the strings of his lyre and threw it away. The lyre was later discovered by the Muses and Apollo's sons Linus and Orpheus. The Muses fixed the middle string, Linus the string struck with the forefinger, and Orpheus the lowest string and the one next to it. They took it back to Apollo, but the god, who had decided to stay away from music for a while, laid away both the lyre and the pipes at Delphi and joined Cybele in her wanderings to as far as Hyperborea.Apostle Arne Horn, The Book of Eusebius #4

Contest with Cinyras

Cinyras was a ruler of Cyprus, who was a friend of Agamemnon. Cinyras promised to assist Agamemnon in the Trojan war, but did not keep his promise. Agamemnon cursed Cinyras. He invoked Apollo and asked the god to avenge the broken promise. Apollo then had a lyre-playing contest with Cinyras, and defeated him. Either Cinyras committed suicide when he lost, or was killed by Apollo.Homer, Iliad, 11.20–23.Eustathius on Iliad; cf. also scholia on the same passage

Patron of sailors
Apollo functions as the patron and protector of sailors, one of the duties he shares with Poseidon. In the myths, he is seen helping heroes who pray to him for a safe journey.

When Apollo spotted a ship of Cretan sailors that were caught in a storm, he quickly assumed the shape of a dolphin and guided their ship safely to Delphi.Homer, Hymn to Pythian Apollo

When the Argonauts faced a terrible storm, Jason prayed to his patron, Apollo, to help them. Apollo used his bow and golden arrow to shed light upon an island, where the Argonauts soon took shelter. This island was renamed "Anaphe", which means "He revealed it".Apollonius of Rhodes, Argonautica

Apollo helped the Greek hero Diomedes, to escape from a great tempest during his journey homeward. As a token of gratitude, Diomedes built a temple in honor of Apollo under the epithet Epibaterius ("the embarker").John Potter, Archaeologia Graeca: Or, The Antiquities of Greece, Volume 1

During the Trojan War, Odysseus came to the Trojan camp to return Chriseis, the daughter of Apollo's priest Chryses, and brought many offerings to Apollo. Pleased with this, Apollo sent gentle breezes that helped Odysseus return safely to the Greek camp.Homer, the Ilaid 1

Arion was a poet who was kidnapped by some sailors for the rich prizes he possessed. Arion requested them to let him sing for the last time, to which the sailors consented. Arion began singing a song in praise of Apollo, seeking the god's help. Consequently, numerous dolphins surrounded the ship and when Arion jumped into the water, the dolphins carried him away safely.

Wars

Trojan War
Apollo played a pivotal role in the entire Trojan War. He sided with the Trojans, and sent a terrible plague to the Greek camp, which indirectly led to the conflict between Achilles and Agamemnon. He killed the Greek heroes Patroclus, Achilles, and numerous Greek soldiers. He also helped many Trojan heroes, the most important one being Hector. After the end of the war, Apollo and Poseidon together cleaned the remains of the city and the camps.

Telegony war
A war broke out between the Brygoi and the Thesprotians, who had the support of Odysseus. The gods Athena and Ares came to the battlefield and took sides. Athena helped the hero Odysseus while Ares fought alongside of the Brygoi. When Odysseus lost, Athena and Ares came into a direct duel. To stop the battling gods and the terror created by their battle, Apollo intervened and stopped the duel between them.Eugammon of Cyrene, Telegony FragmentBenjamin Sammons, Device and Composition in the Greek Epic Cycle

Indian war
When Zeus suggested that Dionysus defeat the Indians in order to earn a place among the gods, Dionysus declared war against the Indians and travelled to India along with his army of Bacchantes and satyrs. Among the warriors was Aristaeus, Apollo's son. Apollo armed his son with his own hands and gave him a bow and arrows and fitted a strong shield to his arm.Nonnus, Dionysiaca 13 After Zeus urged Apollo to join the war, he went to the battlefield.Nonnus, Dionysiaca 27 Seeing several of his nymphs and Aristaeus drowning in a river, he took them to safety and healed them.Nonnus, Dionysiaca 24 He taught Aristaeus more useful healing arts and sent him back to help the army of Dionysus.

Theban war
During the war between the sons of Oedipus, Apollo favored Amphiaraus, a seer and one of the leaders in the war. Though saddened that the seer was fated to be doomed in the war, Apollo made Amphiaraus' last hours glorious by "lighting his shield and his helm with starry gleam". When Hypseus tried to kill the hero with a spear, Apollo directed the spear towards the charioteer of Amphiaraus instead. Then Apollo himself replaced the charioteer and took the reins in his hands. He deflected many spears and arrows away from them. He also killed many of the enemy warriors like Melaneus, Antiphus, Aetion, Polites and Lampus. At last, when the moment of departure came, Apollo expressed his grief with tears in his eyes and bid farewell to Amphiaraus, who was soon engulfed by the Earth.Statius, Thebaid 7

Slaying of giants

Apollo killed the giants Python and Tityos, who had assaulted his mother Leto.

Gigantomachy
During the gigantomachy, Apollo and Heracles blinded the giant Ephialtes by shooting him in his eyes, Apollo shooting his left and Heracles his right.Apollodorus, 1.6.2. He also killed Porphyrion, the king of giants, using his bow and arrows.Pindar, Pythian 8.12–18.

Aloadae
The Aloadae, namely Otis and Ephialtes, were twin giants who decided to wage war upon the gods. They attempted to storm Mt. Olympus by piling up mountains, and threatened to fill the sea with mountains and inundate dry land.Grimal, s.v. Aloadae, p. 34. They even dared to seek the hand of Hera and Artemis in marriage. Angered by this, Apollo killed them by shooting them with arrows.Homer, Odyssey 11.305. According to another tale, Apollo killed them by sending a deer between them; as they tried to kill it with their javelins, they accidentally stabbed each other and died.Hyginus, Fabulae 28.

Phorbas
Phorbas was a savage giant king of Phlegyas who was described as having swine-like features. He wished to plunder Delphi for its wealth. He seized the roads to Delphi and started harassing the pilgrims. He captured the old people and children and sent them to his army to hold them for ransom. And he challenged the young and sturdy men to a match of boxing, only to cut their heads off when they would get defeated by him. He hung the chopped-off heads to an oak tree. Finally, Apollo came to put an end to this cruelty. He entered a boxing contest with Phorbas and killed him with a single blow.Philostratus the Elder, Imagines 2.19.

Other stories

thumb|Apollo as the rising sun, by François Boucher

In the first Olympic games, Apollo defeated Ares and became the victor in wrestling. He outran Hermes in the race and won first place.Herodotus, Histories 5. 7. 10

Apollo divides months into summer and winter.Orphic Hymn 34 to Apollon, 21 (Athanassakis and Wolkow, pp. 30–31). He rides on the back of a swan to the land of the Hyperboreans during the winter months, and the absence of warmth in winter is due to his departure. During his absence, Delphi was under the care of Dionysus, and no prophecies were given during winters.

 Periphas 

Periphas was an Attican king and a priest of Apollo. He was noble, just and rich. He did all his duties justly. Because of this people were very fond of him and started honouring him to the same extent as Zeus. At one point, they worshipped Periphas in place of Zeus and set up shrines and temples for him. This annoyed Zeus, who decided to annihilate the entire family of Periphas. But because he was a just king and a good devotee, Apollo intervened and requested his father to spare Periphas. Zeus considered Apollo's words and agreed to let him live. But he metamorphosed Periphas into an eagle and made the eagle the king of birds. When Periphas' wife requested Zeus to let her stay with her husband, Zeus turned her into a vulture and fulfilled her wish.Antoninus Liberalis, Metamorphoses 6; Grimal, s.v. Periphas (2), p. 359.

 Molpadia and Parthenos 

Molpadia and Parthenos were the sisters of Rhoeo, a former lover of Apollo. One day, they were put in charge of watching their father's ancestral wine jar but they fell asleep while performing this duty. While they were asleep, the wine jar was broken by the swine their family kept. When the sisters woke up and saw what had happened, they threw themselves off a cliff in fear of their father's wrath. Apollo, who was passing by, caught them and carried them to two different cities in Chersonesus, Molpadia to Castabus and Parthenos to Bubastus. He turned them into goddesses and they both received divine honors. Molpadia's name was changed to Hemithea upon her deification.Diodorus Siculus, Library of History, 5. 62. 3-4

 Prometheus 

Prometheus was the titan who was punished by Zeus for stealing fire. He was bound to a rock, where each day an eagle was sent to eat Prometheus' liver, which would then grow back overnight to be eaten again the next day. Seeing his plight, Apollo pleaded with Zeus to release the kind Titan, while Artemis and Leto stood behind him with tears in their eyes. Zeus, moved by Apollo's words and the tears of the goddesses, finally sent Heracles to free Prometheus.Valerius Flaccus, Argonautica 4. 60

thumb|Apollo crowning the arts, by Nicolas-Guy Brenet

 Heracles 

After Heracles (then named Alcides) was struck with madness and killed his family, he sought to purify himself and consulted the oracle of Apollo. Apollo, through the Pythia, commanded him to serve king Eurystheus for twelve years and complete the ten tasks the king would give him. Only then would Alcides be absolved of his sin. Apollo also renamed him Heracles.Apollodorus, 2.4.12.

thumb|right|Heracles and Apollo struggling over the Hind, as depicted on a Corinthian helmet (early 5th century BC)

To complete his third task, Heracles had to capture the Ceryneian Hind, a hind sacred to Artemis, and bring back it alive. After chasing the hind for one year, the animal eventually got tired, and when it tried crossing the river Ladon, Heracles captured it. While he was taking it back, he was confronted by Apollo and Artemis, who were angered at Heracles for this act. However, Heracles soothed the goddess and explained his situation to her. After much pleading, Artemis permitted him to take the hind and told him to return it later.Apollodorus, 2.5.3.

After he was freed from his servitude to Eurystheus, Heracles fell in conflict with Iphytus, a prince of Oechalia, and murdered him. Soon after, he contracted a terrible disease. He consulted the oracle of Apollo once again, in the hope of ridding himself of the disease. The Pythia, however, denied to give any prophesy. In anger, Heracles snatched the sacred tripod and started walking away, intending to start his own oracle. However, Apollo did not tolerate this and stopped Heracles; a duel ensued between them. Artemis rushed to support Apollo, while Athena supported Heracles. Soon, Zeus threw his thunderbolt between the fighting brothers and separated them. He reprimanded Heracles for this act of violation and asked Apollo to give a solution to Heracles. Apollo then ordered the hero to serve under Omphale, queen of Lydia for one year in order to purify himself.

After their reconciliation, Apollo and Heracles together founded the city of Gythion.Pausanias, Description of Greece 3. 21. 8

 Plato's concept of soulmates 

A long time ago, there were three kinds of human beings: male, descended from the sun; female, descended from the earth; and androgynous, descended from the moon. Each human being was completely round, with four arms and four legs, two identical faces on opposite sides of a head with four ears, and all else to match. They were powerful and unruly. Otis and Ephialtes even dared to scale Mount Olympus.

To check their insolence, Zeus devised a plan to humble them and improve their manners instead of completely destroying them. He cut them all in two and asked Apollo to make necessary repairs, giving humans the individual shape they still have now. Apollo turned their heads and necks around towards their wounds, he pulled together their skin at the abdomen, and sewed the skin together at the middle of it. This is what we call navel today. He smoothened the wrinkles and shaped the chest. But he made sure to leave a few wrinkles on the abdomen and around the navel so that they might be reminded of their punishment.Plato, The Symposium

 The rock of Leukas 

Leukatas was believed to be a white-colored rock jutting out from the island of Leukas into the sea. It was present in the sanctuary of Apollo Leukates. A leap from this rock was believed to have put an end to the longings of love.Strabo, Geography, 10.2.8.

Once, Aphrodite fell deeply in love with Adonis, a young man of great beauty who was later accidentally killed by a boar. Heartbroken, Aphrodite wandered looking for the rock of Leukas. When she reached the sanctuary of Apollo in Argos, she confided in him her love and sorrow. Apollo then brought her to the rock of Leukas and asked her to throw herself from the top of the rock. She did so and was freed from her love. When she sought the reason behind this, Apollo told her that Zeus, before taking another lover, would sit on this rock to free himself from his love for Hera.Ptolemy Hephaestion, New History Book 7

Another tale relates that a man named Nireus, who fell in love with the cult statue of Athena, came to the rock and jumped in order to relieve himself. After jumping, he fell into the net of a fisherman in which, when he was pulled out, he found a box filled with gold. He fought with the fisherman and took the gold, but Apollo appeared to him in the night in a dream and warned him not to appropriate gold which belonged to others.

It was an ancestral custom among the Leukadians to fling a criminal from this rock every year at the sacrifice performed in honor of Apollo for the sake of averting evil. However, a number of men would be stationed all around below rock to catch the criminal and take him out of the borders in order to exile him from the island.Aelian, On Animals 11. 8 This was the same rock from which, according to a legend, Sappho took her suicidal leap.

 Slaying of Titans 
Once Hera, out of spite, aroused the Titans to war against Zeus and take away his throne. Accordingly, when the Titans tried to climb Mount Olympus, Zeus with the help of Apollo, Artemis and Athena, defeated them and cast them into Tartarus.Hyginus, Fabulae 150.

Female lovers

Love affairs ascribed to Apollo are a late development in Greek mythology."The love-stories themselves were not told until later." Karl Kerenyi, The Gods of the Greeks 1951:140. Their vivid anecdotal qualities have made some of them favorites of painters since the Renaissance, the result being that they stand out more prominently in the modern imagination.

Daphne was a nymph who scorned Apollo's advances and ran away from him. When Apollo chased her in order to persuade her, she changed herself into a laurel tree. According to other versions, she cried for help during the chase, and Gaia helped her by taking her in and placing a laurel tree in her place.Hyginus, Fabulae 203. According to Roman poet Ovid, the chase was brought about by Cupid, who hit Apollo with a golden arrow of love and Daphne with a leaden arrow of hatred.Ovid, Metamorphoses 1.452-567; Tripp, s.v. Daphne. The myth explains the origin of the laurel and the connection of Apollo with the laurel and its leaves, which his priestess employed at Delphi. The leaves became the symbol of victory and laurel wreaths were given to the victors of the Pythian games.

thumb|Apollo and the Muses, by Robert Sanderson
Apollo is said to have been the lover of all nine Muses, and not being able to choose one of them, decided to remain unwed. He fathered the Corybantes by the Muse Thalia,Apollodorus, 1.3.4. Orpheus by Calliope, Linus of Thrace by Calliope or Urania and Hymenaios (Hymen) by one of the Muses.

In the Great Eoiae that is attributed to Hesoid, Scylla is the daughter of Apollo and Hecate.Scholiast on Apollonius Rhodius, Arg. iv. 828

Cyrene was a Thessalian princess whom Apollo loved. In her honor, he built the city Cyrene and made her its ruler. She was later granted longevity by Apollo who turned her into a nymph. The couple had two sons, Aristaeus, and Idmon.

Evadne was a nymph daughter of Poseidon and a lover of Apollo. They had a son, Iamos. During the time of the childbirth, Apollo sent Eileithyia, the goddess of childbirth to assist her.

Rhoeo, a princess of the island of Naxos was loved by Apollo. Out of affection for her, Apollo turned her sisters into goddesses. On the island Delos she bore Apollo a son named Anius. Not wanting to have the child, she entrusted the infant to Apollo and left. Apollo raised and educated the child on his own.

Ourea, a daughter of Poseidon, fell in love with Apollo when he and Poseidon were serving the Trojan king Laomedon. They both united on the day the walls of Troy were built. She bore to Apollo a son, whom Apollo named Ileus, after the city of his birth, Ilion (Troy). Ileus was very dear to Apollo.Scholia on Tzetzes' Exegesis in Iliadem 1.126 [= Hesiod Catalogue of Women fr. 83].

Thero, daughter of Phylas, a maiden as beautiful as the moonbeams, was loved by the radiant Apollo, and she loved him in return. Through their union, she became the mother of Chaeron, who was famed as "the tamer of horses". He later built the city Chaeronea.Pausanias, Description of Greece 9

Hyrie or Thyrie was the mother of Cycnus. Apollo turned both the mother and son into swans when they jumped into a lake and tried to kill themselves.Antoninus Liberalis, Metamorphoses 12; Ovid, Metamorphoses 7.350; Smith 1873, s.v. Cycnus (1).

Hecuba was the wife of King Priam of Troy, and Apollo had a son with her named Troilus. An oracle prophesied that Troy would not be defeated as long as Troilus reached the age of twenty alive. He was ambushed and killed by Achilleus, and Apollo avenged his death by killing Achilles. After the sack of Troy, Hecuba was taken to Lycia by Apollo.Stesichorus, Fr.108

Coronis was daughter of Phlegyas, King of the Lapiths. While pregnant with Asclepius, Coronis fell in love with Ischys, son of Elatus and slept with him. When Apollo found out about her infidelity through his prophetic powers or thanks to his raven who informed him, he sent his sister, Artemis, to kill Coronis. Apollo rescued the baby by cutting open Koronis' belly and gave it to the centaur Chiron to raise.

Dryope, the daughter of Dryops, was impregnated by Apollo in the form of a snake. She gave birth to a son named Amphissus.Antoninus Liberalis, Metamorphoses, 32; Ovid, Metamorphoses 9.330.

In Euripides' play Ion, Apollo fathered Ion by Creusa, wife of Xuthus. He used his powers to conceal her pregnancy from her father. Later, when Creusa left Ion to die in the wild, Apollo asked Hermes to save the child and bring him to the oracle at Delphi, where he was raised by a priestess.

Apollo loved and kidnapped an Oceanid nymph, Melia. Her father Oceanus sent one of his sons, Caanthus, to find her, but Caanthus could not take her back from Apollo, so he burned Apollo's sanctuary. In retaliation, Apollo shot and killed Caanthus.Pausanias, 9.10.5–6.

Male lovers
thumb|Apollo and Hyacinthus, by Carlo Cesio
thumb|left|Death of Hyacinth, by Alexander Kiselyov, 1850–1900

Hyacinth (or Hyacinthus), a beautiful and athletic Spartan prince, was one of Apollo's favourite lovers.Ovid, Metamorphoses 10.143 ff. The pair was practicing throwing the discus when a discus thrown by Apollo was blown off course by the jealous Zephyrus and struck Hyacinthus in the head, killing him instantly. Apollo is said to be filled with grief. Out of Hyacinthus' blood, Apollo created a flower named after him as a memorial to his death, and his tears stained the flower petals with the interjection , meaning alas., . He was later resurrected and taken to heaven. The festival Hyacinthia was a national celebration of Sparta, which commemorated the death and rebirth of Hyacinthus.Smith 1890, s.v. Hyacinthia.

Another male lover was Cyparissus, a descendant of Heracles. Apollo gave him a tame deer as a companion but Cyparissus accidentally killed it with a javelin as it lay asleep in the undergrowth. Cyparissus was so saddened by its death that he asked Apollo to let his tears fall forever. Apollo granted the request by turning him into the Cypress named after him, which was said to be a sad tree because the sap forms droplets like tears on the trunk.Ovid, Metamorphoses 10.106-10.142; Tripp, s.v. Cyparissus.

thumb|200px|Apollo and Cyparissus, by Jean-Pierre Granger (1779–1840)

Admetus, the king of Pherae, was also Apollo's lover.Callimachus, Hymn to Apollo, 49.Plutarch, Life of Numa, 4.5. During his exile, which lasted either for one year or nine years, Apollo served Admetus as a herdsman. The romantic nature of their relationship was first described by Callimachus of Alexandria, who wrote that Apollo was "fired with love" for Admetus. Plutarch lists Admetus as one of Apollo's lovers and says that Apollo served Admetus because he doted upon him.Plutarch, Amatorius 17 Latin poet Ovid in his  said that even though he was a god, Apollo forsook his pride and stayed in as a servant for the sake of Admetus.Ovid, Ars Amatoria 2.239 Tibullus describes Apollo's love to the king as servitium amoris (slavery of love) and asserts that Apollo became his servant not by force but by choice. He would also make cheese and serve it to Admetus. His domestic actions caused embarrassment to his family.Tibullus, Elegies 2.3

thumb|250px|Apollo visiting Admetus, by Nicolas-Antoine Taunay, 19th century

When Admetus wanted to marry princess Alcestis, Apollo provided a chariot pulled by a lion and a boar he had tamed. This satisfied Alcestis' father and he let Admetus marry his daughter. Further, Apollo saved the king from Artemis' wrath and also convinced the Moirai to postpone Admetus' death once.

Branchus, a shepherd, one day came across Apollo in the woods. Captivated by the god's beauty, he kissed Apollo. Apollo requited his affections and wanting to reward him, bestowed prophetic skills on him. His descendants, the Branchides, were an influential clan of prophets.Pepin, Ronald E. (2008). The Vatican Mythographers. Fordham Univ Press. .

Other male lovers of Apollo include:

Adonis, who is said to have been the lover of both Apollo and Aphrodite. He behaved as a man with Aphrodite and as a woman with Apollo.Ptolemy Hephaestion, New History Book 4 (summary from Photius, Myriobiblon 190)

Children

Apollo sired many children, from mortal women and nymphs as well as the goddesses. His children grew up to be physicians, musicians, poets, seers or archers. Many of his sons founded new cities and became kings.

thumb|Apollo Entrusting Chiron with the Education of Aescalapius

Asclepius is the most famous son of Apollo. His skills as a physician surpassed that of Apollo's. Zeus killed him for bringing back the dead, but upon Apollo's request, he was resurrected as a god. 
Aristaeus was placed under the care of Chiron after his birth. He became the god of beekeeping, cheese-making, animal husbandry and more. He was ultimately given immortality for the benefits he bestowed upon humanity. The Corybantes were spear-clashing, dancing demigods.

The sons of Apollo who participated in the Trojan War include the Trojan princes Hector and Troilus, as well as Tenes, the king of Tenedos, all three of whom were killed by Achilles over the course of the war.

Apollo's children who became musicians and bards include Orpheus, Linus, Ialemus, Hymenaeus, Philammon, Eumolpus and Eleuther. Apollo fathered 3 daughters, Apollonis, Borysthenis and Cephisso, who formed a group of minor Muses, the "Musa Apollonides".Eumelus, Fragment 35 (from Tzetzes, On Hesiod's Works & Days 23) They were nicknamed Nete, Mese and Hypate after the highest, middle and lowest strings of his lyre. Phemonoe was a seer and poet who was the inventor of Hexameter.

Apis, Idmon, Iamus, Tenerus, Mopsus, Galeus, Telmessus and others were gifted seers. Anius, Pythaeus and Ismenus lived as high priests. Most of them were trained by Apollo himself.

Arabus, Delphos, Dryops, Miletos, Tenes, Epidaurus, Ceos, Lycoras, Syrus, Pisus, Marathus, Megarus, Patarus, Acraepheus, Cicon, Chaeron and many other sons of Apollo, under the guidance of his words, founded eponymous cities.

He also had a son named Chrysorrhoas who was a mechanic artist.Plutarch, Of the Names of Rivers and Mountains, and Of Such Things as are to be Found Therein His other daughters include Eurynome, Chariclo wife of Chiron, Eurydice the wife of Orpheus, Eriopis, famous for her beautiful hair, Melite the heroine, Pamphile the silk weaver, Parthenos, and by some accounts, Phoebe, Hilyra and Scylla. Apollo turned Parthenos into a constellation after her early death.

Additionally, Apollo fostered and educated Chiron, the centaur who later became the greatest teacher and educated many demigods, including Apollo's sons. Apollo also fostered Carnus, the son of Zeus and Europa.

The relevant passage in Stephanus in fact reads: "Acraephia... was founded either by Athamas or by Acraepheus, son of Apollo. The mountain is named after Ptous, son of the aforesaid individual (τοῦ αὐτοῦ) and Euxippe". The version given in scholia on Pausanias has prompted several scholars to emend "Euxippe" to "Zeuxippe", and to assume that "τοῦ αὐτοῦ" refers to Apollo rather than Acraepheus. Such an interpretation, however, has been contested on the strength of the facts that Stephanus must have closely followed Herodianus, where the parents' names are unambiguously Acraepheus and Euxippe, and that the passage in scholia on Pausanias allows for an alternate understanding that doesn't necessarily make Apollo and Zeuxippe parents of Ptous.

Failed love attempts

Marpessa was kidnapped by Idas but was loved by Apollo as well. Zeus made her choose between them, and she chose Idas on the grounds that Apollo, being immortal, would tire of her when she grew old.Apollodorus, 1.7.8–9; cf. Homer, Iliad 9.557–560.

Sinope, a nymph, was approached by the amorous Apollo. She made him promise that he would grant to her whatever she would ask for, and then cleverly asked him to let her stay a virgin. Apollo kept his promise and went back.

Bolina was admired by Apollo but she refused him and jumped into the sea. To avoid her death, Apollo turned her into a nymph, saving her life.

Castalia was a nymph whom Apollo loved. She fled from him and dove into the spring at Delphi, at the base of Mt. Parnassos, which was then named after her. Water from this spring was sacred; it was used to clean the Delphian temples and inspire the priestesses.Statius, Thebaid 1.696 ff.

Cassandra, was a daughter of Hecuba and Priam. Apollo wished to court her. Cassandra promised to return his love on one condition - he should give her the power to see the future. Apollo fulfilled her wish, but she went back on her word and rejected him soon after. Angered that she broke her promise, Apollo cursed her that even though she would see the future, no one would ever believe her prophecies.

The Sibyl of Cumae like Cassandra promised Apollo her love if he would give her a boon. The Sibyl took a handful of sand and asked Apollo to grant her years of life as many as the grains of sand she held in her hands. Apollo granted her wish, but Sibyl went back on her word. Although Sibyl did live an extended life as Apollo had promised, he did not give her agelessness along with it, so she shrivelled and shrank and only her voice remained.Ovid, Metamorphoses 14.129-154

Hestia, the goddess of the hearth, rejected both Apollo's and Poseidon's marriage proposals and swore that she would always stay unmarried.

In one version of the prophet Tiresias's origins, he was originally a woman who promised Apollo to sleep with him if he would give her music lessons. Apollo gave her her wish, but then she went back on her word and refused him. Apollo in anger turned her into a man.

Female counterparts

thumb|200px|Apollo and Artemis, by Gavin Hamilton|left

Artemis

thumb|220px|Apollo (left) and Artemis. Brygos (potter signed), tondo of an Attic red-figure cup c. 470 BC, Musée du Louvre.

Artemis as the sister of Apollo, is thea apollousa, that is, she as a female divinity represented the same idea that Apollo did as a male divinity. In the pre-Hellenic period, their relationship was described as the one between husband and wife, and there seems to have been a tradition which actually described Artemis as the wife of Apollo. However, this relationship was never sexual but spiritual,Eustath. ad Hom. p. 1197 which is why they both are seen being unmarried in the Hellenic period.

Artemis, like her brother, is armed with a bow and arrows. She is the cause of sudden deaths of women. She also is the protector of the young, especially girls. Though she has nothing to do with oracles, music or poetry, she sometimes led the female chorus on Olympus while Apollo sang.The Oxford Encyclopedia of Ancient Greece and Rome s.v. Artemis, p. 268 The laurel (daphne) was sacred to both. Artemis Daphnaia had her temple among the Lacedemonians, at a place called Hypsoi.G. Shipley, "The Extent of Spartan Territory in the Late Classical and Hellenistic Periods", The Annual of the British School at Athens, 2000. 
Apollo Daphnephoros had a temple in Eretria, a "place where the citizens are to take the oaths".Rufus B. Richardson, "A Temple in Eretria" The American Journal of Archaeology and of the History of the Fine Arts, 10.3 (July - September 1895:326–337); Paul Auberson, Eretria. Fouilles et Recherches I, Temple d'Apollon Daphnéphoros, Architecture (Bern, 1968). See also Plutarch, Pythian Oracle, 16. In later times when Apollo was regarded as identical with the sun or Helios, Artemis was naturally regarded as Selene or the moon.

Hecate

thumb|Hecate's procession by the witches, by Jusepe de Ribera

Hecate, the goddess of witchcraft and magic, is the chthonic counterpart of Apollo. They both are cousins, since their mothers - Leto and Asteria - are sisters. One of Apollo's epithets, Hecatos, is the masculine form of Hecate, and both names mean "working from afar". While Apollo presided over the prophetic powers and magic of light and heaven, Hecate presided over the prophetic powers and magic of night and chthonian darkness. If Hecate is the "gate-keeper", Apollo Agyieus is the "door-keeper". Hecate is the goddess of crossroads and Apollo is the god and protector of streets.Carol M. Mooney, B.A., Hekate: Her Role And Character In Greek Literature From Before The Fifth Century B.C.

thumb|left|200px|Pallas Athene Visiting Apollo on the Parnassus, by Arnold Houbraken

The oldest evidence found for Hecate's worship is at Apollo's temple in Miletos. There, Hecate was taken to be Apollo's sister counterpart in the absence of Artemis. Hecate's lunar nature makes her the goddess of the waning moon and contrasts and complements, at the same time, Apollo's solar nature.

Athena

As a deity of knowledge and great power, Apollo was seen being the male counterpart of Athena. Being Zeus' favorite children, they were given more powers and duties. Apollo and Athena often took up the role of protectors of cities, and were patrons of some of the important cities. Athena was the principal goddess of Athens, Apollo was the principal god of Sparta.

As patrons of arts, Apollo and Athena were companions of the Muses, the former a much more frequent companion than the latter.Peter Dawkins, The Shakespeare Enigma Apollo was sometimes called the son of Athena and Hephaestus.Cicero, De Natura Deorum 3.22.

In the Trojan War, as Zeus' executive, Apollo is seen holding the aegis like Athena usually does.Homer, Iliad 15.308. Apollo's decisions were usually approved by his sister Athena, and they both worked to establish the law and order set forth by Zeus.1.Homer, Iliad, Euripides, Ion, Aeschylus, Oresteia

Apollo in the Oresteia
In Aeschylus' Oresteia trilogy, Clytemnestra kills her husband, King Agamemnon because he had sacrificed their daughter Iphigenia to proceed forward with the Trojan war. Apollo gives an order through the Oracle at Delphi that Agamemnon's son, Orestes, is to kill Clytemnestra and Aegisthus, her lover. Orestes and Pylades carry out the revenge, and consequently Orestes is pursued by the Erinyes or Furies (female personifications of vengeance).

Apollo and the Furies argue about whether the matricide was justified; Apollo holds that the bond of marriage is sacred and Orestes was avenging his father, whereas the Erinyes say that the bond of blood between mother and son is more meaningful than the bond of marriage. They invade his temple, and he drives them away. He says that the matter should be brought before Athena. Apollo promises to protect Orestes, as Orestes has become Apollo's supplicant. Apollo advocates Orestes at the trial, and ultimately Athena rules in favor of Apollo.

Roman Apollo

The Roman worship of Apollo was adopted from the Greeks. As a quintessentially Greek god, Apollo had no direct Roman equivalent, although later Roman poets often referred to him as Phoebus. There was a tradition that the Delphic oracle was consulted as early as the period of the kings of Rome during the reign of Tarquinius Superbus.Livy 1.56.

On the occasion of a pestilence in the 430s BCE, Apollo's first temple at Rome was established in the Flaminian fields, replacing an older cult site there known as the "Apollinare".Livy 3.63.7, 4.25.3. During the Second Punic War in 212 BCE, the Ludi Apollinares ("Apollonian Games") were instituted in his honor, on the instructions of a prophecy attributed to one Marcius.Livy 25.12. In the time of Augustus, who considered himself under the special protection of Apollo and was even said to be his son, his worship developed and he became one of the chief gods of Rome.

After the Battle of Actium, which was fought near a sanctuary of Apollo, Augustus enlarged Apollo's temple, dedicated a portion of the spoils to him, and instituted quinquennial games in his honour.Suetonius, Augustus 18.2; Cassius Dio 51.1.1–3. He also erected a new temple to the god on the Palatine hill.Cassius Dio 53.1.3. Sacrifices and prayers on the Palatine to Apollo and Diana formed the culmination of the Secular Games, held in 17 BCE to celebrate the dawn of a new era.Inscriptiones Latinae Selectae 5050, translated by 

Festivals
The chief Apollonian festival was the Pythian Games held every four years at Delphi and was one of the four great Panhellenic Games. Also of major importance was the Delia held every four years on Delos.
Athenian annual festivals included the Boedromia, Metageitnia,Smith 1890, s.v. MACELLUM, MATRA'LIA, METAGEI'TNIA. Pyanepsia, and Thargelia.
Spartan annual festivals were the Carneia and the Hyacinthia.
Thebes every nine years held the Daphnephoria.

Attributes and symbols

Apollo's most common attributes were the bow and arrow. Other attributes of his included the kithara (an advanced version of the common lyre), the plectrum and the sword. Another common emblem was the sacrificial tripod, representing his prophetic powers. The Pythian Games were held in Apollo's honor every four years at Delphi. The bay laurel plant was used in expiatory sacrifices and in making the crown of victory at these games.

thumb|left|250px|Gold stater of the Seleucid king Antiochus I Soter (reigned 281–261 BCE) showing on the reverse a nude Apollo holding his key attributes: two arrows and a bow

The palm tree was also sacred to Apollo because he had been born under one in Delos. Animals sacred to Apollo included wolves, dolphins, roe deer, swans, cicadas (symbolizing music and song), ravens, hawks, crows (Apollo had hawks and crows as his messengers), snakes (referencing Apollo's function as the god of prophecy), mice and griffins, mythical eagle–lion hybrids of Eastern origin.

Homer and Porphyry wrote that Apollo had a hawk as his messenger.Homer, Odyssey, 15.493Porphyry, De abstinentia, 3.5 In many myths Apollo is transformed into a hawk.Antoninus Liberalis, Metamorphoses, 28Ovid, Metamorphoses, 6.103Ovid, Metamorphoses, 11.318 In addition, Claudius Aelianus wrote that in Ancient Egypt people believed that hawks were sacred to the god and that according to the ministers of Apollo in Egypt there were certain men called "hawk-keepers" (ἱερακοβοσκοί) who fed and tended the hawks belonging to the god.Aelian, Characteristics of Animals, 7.9 Eusebius wrote that the second appearance of the moon is held sacred in the city of Apollo in Egypt and that the city's symbol is a man with a hawklike face (Horus).Eusebius, Preparation of the Gospels, 3.12.1 Claudius Aelianus wrote that Egyptians called Apollo Horus in their own language.Aelian, Characteristics of Animals, 10.14

As god of colonization, Apollo gave oracular guidance on colonies, especially during the height of colonization, 750–550 BCE. According to Greek tradition, he helped Cretan or Arcadian colonists found the city of Troy. However, this story may reflect a cultural influence which had the reverse direction: Hittite cuneiform texts mention an Asia Minor god called Appaliunas or Apalunas in connection with the city of Wilusa attested in Hittite inscriptions, which is now generally regarded as being identical with the Greek Ilion by most scholars. In this interpretation, Apollo's title of Lykegenes can simply be read as "born in Lycia", which effectively severs the god's supposed link with wolves (possibly a folk etymology).

In literary contexts, Apollo represents harmony, order, and reason—characteristics contrasted with those of Dionysus, god of wine, who represents ecstasy and disorder. The contrast between the roles of these gods is reflected in the adjectives Apollonian and Dionysian. However, the Greeks thought of the two qualities as complementary: the two gods are brothers, and when Apollo at winter left for Hyperborea, he would leave the Delphic oracle to Dionysus. This contrast appears to be shown on the two sides of the Borghese Vase.

Apollo is often associated with the Golden Mean. This is the Greek ideal of moderation and a virtue that opposes gluttony.

In antiquity, Apollo was associated with the planet Mercury. The ancient Greeks believed that Mercury as observed during the morning was a different planet than the one during the evening, because each twilight Mercury would appear farther from the Sun as it set than it had the night before. The morning planet was called Apollo, and the one at evening Hermes/Mercury before they realised they were the same, thereupon the name 'Mercury/Hermes' was kept, and 'Apollo' was dropped.

Apollo in the arts
thumb|Statue of Apollo at the Academy of Athens
Apollo is a common theme in Greek and Roman art and also in the art of the Renaissance. The earliest Greek word for a statue is "delight" (, agalma), and the sculptors tried to create forms which would inspire such guiding vision. Maurice Bowra notices that the Greek artist puts into a god the highest degree of power and beauty that can be imagined. The sculptors derived this from observations on human beings, but they also embodied in concrete form, issues beyond the reach of ordinary thought.C.M.Bowra , The Greek eperience, p. 148,149.

The naked bodies of the statues are associated with the cult of the body which was essentially a religious activity.C.M.Bowra The Greek eperience, p. 148,150:The World publishing company. The muscular frames and limbs combined with slim waists indicate the Greek desire for health, and the physical capacity which was necessary in the hard Greek environment.C.M.Bowra, The Greek eperience, p.5 The statues of Apollo and the other gods present them in their full youth and strength. "In the balance and relation of their limbs, such figures express their whole character, mental and physical, and reveal their central being . ,the radiant reality of youth in its heyday".C.M.Bowra The Greek experience, p.150

Archaic sculpture
Numerous free-standing statues of male youths from Archaic Greece exist, and were once thought to be representations of Apollo, though later discoveries indicated that many represented mortals.Delphi, 467, 1524 In 1895, V. I. Leonardos proposed the term kouros ("male youth") to refer to those from Keratea; this usage was later expanded by Henri Lechat in 1904 to cover all statues of this format.V.I. Leonardos(1895). Archaelogiki Ephimeris, Col 75, n 1.Lechat (1904). La sculpture Attic avant Phidias, p. 23.

The earliest examples of life-sized statues of Apollo may be two figures from the Ionic sanctuary on the island of Delos. Such statues were found across the Greek-speaking world, the preponderance of these were found at the sanctuaries of Apollo with more than one hundred from the sanctuary of Apollo Ptoios, Boeotia alone.J. Ducat (1971). Les Kouroi des Ptoion. Significantly more rare are the life-sized bronze statues. One of the few originals which survived into the present day—so rare that its discovery in 1959 was described as "a miracle" by Ernst Homann-Wedeking—is the masterpiece bronze, Piraeus Apollo. It was found in Piraeus, a port city close to Athens, and is believed to have come from north-eastern Peloponnesus. It is the only surviving large-scale Peloponnesian statue.

Classical sculpture

The famous Apollo of Mantua and its variants are early forms of the Apollo Citharoedus statue type, in which the god holds the cithara, a sophisticated seven-stringed variant of the lyre, in his left arm. While none of the Greek originals have survived, several Roman copies from approximately the late 1st or early 2nd century exist, of which an example is the Apollo Barberini.

Hellenistic Greece-Rome
Apollo as a handsome beardless young man, is often depicted with a cithara (as Apollo Citharoedus) or bow in his hand, or reclining on a tree (the Apollo Lykeios and Apollo Sauroctonos types). The Apollo Belvedere is a marble sculpture that was rediscovered in the late 15th century; for centuries it epitomized the ideals of Classical Antiquity for Europeans, from the Renaissance through the 19th century. The marble is a Hellenistic or Roman copy of a bronze original by the Greek sculptor Leochares, made between 330 and 320 BCE.

The life-size so-called "Adonis" found in 1780 on the site of a villa suburbana near the Via Labicana in the Roman suburb of Centocelle is identified as an Apollo by modern scholars. In the late 2nd century CE floor mosaic from El Djem, Roman Thysdrus, he is identifiable as Apollo Helios by his effulgent halo, though now even a god's divine nakedness is concealed by his cloak, a mark of increasing conventions of modesty in the later Empire.

Another haloed Apollo in mosaic, from Hadrumentum, is in the museum at Sousse. The conventions of this representation, head tilted, lips slightly parted, large-eyed, curling hair cut in locks grazing the neck, were developed in the 3rd century BCE to depict Alexander the Great.Bieber 1964, Yalouris 1980. Some time after this mosaic was executed, the earliest depictions of Christ would also be beardless and haloed.

Modern reception
Apollo often appears in modern and popular culture due to his status as the god of music, dance and poetry.

 Postclassical art and literature

 Dance and music 
Apollo has featured in dance and music in modern culture. Percy Bysshe Shelley composed a "Hymn of Apollo" (1820), and the god's instruction of the Muses formed the subject of Igor Stravinsky's Apollon musagète (1927–1928). In 1978, the Canadian band Rush released an album with songs "Apollo: Bringer of Wisdom"/"Dionysus: Bringer of Love".

 Books 
Apollo has been portrayed in modern literature, such as when Charles Handy, in Gods of Management (1978) uses Greek gods as a metaphor to portray various types of organizational culture. Apollo represents a 'role' culture where order, reason, and bureaucracy prevail.British Library: Management and Business Studies Portal, Charles Handy , accessed 12 November 2016 In 2016, author Rick Riordan published the first book in the Trials of Apollo series, publishing four other books in the series in 2017, 2018, 2019 and 2020.

 Film 
Apollo has been depicted in modern films—for instance, by Keith David in the 1997 animated feature film Hercules, by Luke Evans in the 2010 action film Clash of the Titans, and by Dimitri Lekkos in the 2010 film Percy Jackson & the Olympians: The Lightning Thief.

 Video games 
Apollo has appeared in many modern video games. Apollo appears as a minor character in Santa Monica Studio's 2010 action-adventure game God of War III with his bow being used by Peirithous. He also appears in the 2014 Hi-Rez Studios Multiplayer Online Battle Arena game Smite as a playable character.

 Psychology and philosophy 

In the philosophical discussion of the arts, a distinction is sometimes made between the Apollonian and Dionysian impulses, where the former is concerned with imposing intellectual order and the latter with chaotic creativity. Friedrich Nietzsche argued that a fusion of the two was most desirable. Psychologist Carl Jung's Apollo archetype represents what he saw as the disposition in people to over-intellectualise and maintain emotional distance.Shinoda-Bolen, J., Gods in Everyman: A New Psychology of Men's Lives and Loves p.130-160 (1989)

 Spaceflight 

In spaceflight, the 1960s and 1970s NASA program for orbiting and landing astronauts on the Moon was named after Apollo, by NASA manager Abe Silverstein:
