The Nemean lion was killed by the son of which Greek gods?
Heracles Heracles ( ; Ancient Greek: Ἡρακλῆς , "Hēraklēs", from "Hēra", "Hera"), born Alcaeus (Ἀλκαῖος , "Alkaios") or Alcides (Ἀλκείδης , "Alkeidēs"), was a divine hero in Greek mythology, the son of Zeus and Alcmene, foster son of Amphitryon and great-grandson and half-brother (as they are both sired by the god Zeus) of Perseus. He was the greatest of the Greek heroes, a paragon of masculinity, the ancestor of royal clans who claimed to be Heracleidae (Ἡρακλεῖδαι ), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. The Romans adopted the Greek version of his life and works essentially unchanged, but added anecdotal detail of their own, some of it linking the hero with the geography of the Central Mediterranean. Details of his cult were adapted to Rome as well.
Dionysus Dionysus ( ; Greek: Διόνυσος "Dionysos") is the god of the grape harvest, winemaking and wine, of ritual madness, fertility, theatre and religious ecstasy in ancient Greek religion and myth. Wine played an important role in Greek culture, and the cult of Dionysus was the main religious focus for its unrestrained consumption. His worship became firmly established in the seventh century BC. He may have been worshipped as early as c. 1500–1100 BC by Mycenean Greeks; traces of Dionysian-type cult have also been found in ancient Minoan Crete. His origins are uncertain, and his cults took many forms; some are described by ancient sources as Thracian, others as Greek. In some cults, he arrives from the east, as an Asiatic foreigner; in others, from Ethiopia in the South. He is a god of epiphany, "the god that comes", and his "foreignness" as an arriving outsider-god may be inherent and essential to his cults. He is a major, popular figure of Greek mythology and religion, becoming increasingly important over time, and included in some lists of the twelve Olympians, as the last of their number, and the only god born from a mortal mother. His festivals were the driving force behind the development of Greek theatre.
