Omphale

In Greek mythology, Omphale (Ancient Greek: Ὀμφάλη) was a daughter of Iardanus, either a king of Lydia, or a river-god. Omphale was queen of the kingdom of Lydia in Asia Minor; according to Bibliotheke she was the wife of Tmolus, the oak-clad mountain king of Lydia; after he was gored to death by a bull, she continued to reign on her own.

Diodorus Siculus provides the first appearance of the Omphale theme in literature, though Aeschylus was aware of the episode. The Greeks did not recognize her as a goddess: the undisputed etymological connection with omphalos, the world-navel, has never been made clear. In her best-known myth, she is the mistress of the hero Heracles during a year of required servitude, a scenario that offered writers and artists opportunities to explore gender roles and erotic themes.
