Lydian mythology is virtually unknown, and their literature and rituals have been lost due to the absence of any monuments or archaeological finds with extensive inscriptions; therefore, myths involving Lydia are mainly from Greek mythology.

For the Greeks, Tantalus was a primordial ruler of mythic Lydia, and Niobe his proud daughter; her husband Amphion associated Lydia with Thebes in Greece, and through Pelops the line of Tantalus was part of the founding myths of Mycenae's second dynasty. (
In reference to the myth of Bellerophon, Karl Kerenyi remarked, in The Heroes of The Greeks 1959, p. 83. "
As Lykia was thus connected with Crete, and as the person of Pelops, the hero of Olympia, connected Lydia with the Peloponnesos, so Bellerophontes connected another Asian country, or rather two, Lykia and Karia, with the kingdom of Argos".)

In Greek myth, Lydia had also adopted the double-axe symbol, that also appears in the Mycenaean civilization, the labrys.
Omphale, daughter of the river Iardanos, was a ruler of Lydia, whom Heracles was required to serve for a time.
His adventures in Lydia are the adventures of a Greek hero in a peripheral and foreign land: during his stay, Heracles enslaved the Itones; killed Syleus, who forced passers-by to hoe his vineyard; slew the serpent of the river Sangarios (which appears in the heavens as the constellation Ophiucus) and captured the simian tricksters, the Cercopes.
Accounts tell of at least one son of Heracles who was born to either Omphale or a slave-girl: Herodotus (Histories i. 7) says this was Alcaeus who began the line of Lydian Heracleidae which ended with the death of Candaules c. 687 BC.
Diodorus Siculus (4.31.8) and Ovid (Heroides 9.54) mention a son called Lamos, while pseudo-Apollodorus (Bibliotheke 2.7.8) gives the name Agelaus and Pausanias (2.21.3) names Tyrsenus as the son of Heracles by "the Lydian woman".
All three heroic ancestors indicate a Lydian dynasty claiming Heracles as their ancestor.
Herodotus (1.7) refers to a Heraclid dynasty of kings who ruled Lydia, yet were perhaps not descended from Omphale.
He also mentions (1.94) the legend that the Etruscan civilization was founded by colonists from Lydia led by Tyrrhenus, brother of Lydus.
Dionysius of Halicarnassus was skeptical of this story, indicating that the Etruscan language and customs were known to be totally dissimilar to those of the Lydians.
In addition, the story of the "Lydian" origins of the Etruscans was not known to Xanthus of Lydia, an authority on the history of the Lydians.

Later chronologists ignored Herodotus' statement that Agron was the first Heraclid to be a king, and included his immediate forefathers Alcaeus, Belus and Ninus in their list of kings of Lydia.
Strabo (5.2.2) has Atys, father of Lydus and Tyrrhenus, as a descendant of Heracles and Omphale but that contradicts virtually all other accounts which name Atys, Lydus and Tyrrhenus among the pre-Heraclid kings and princes of Lydia.
The gold deposits in the river Pactolus that were the source of the proverbial wealth of Croesus (Lydia's last king) were said to have been left there when the legendary king Midas of Phrygia washed away the "Midas touch" in its waters.

In Euripides' tragedy The Bacchae, Dionysus, while he is maintaining his human disguise, declares his country to be Lydia.
