"In Greek mythology, Omphale (/ˈɒmfəˌliː/; Ancient Greek: Ὀμφάλη) was queen of the kingdom of Lydia in Asia Minor. 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 sexual roles and erotic themes." - (en.wikipedia.org 31.01.2020)
