Lydian queen of Maionia/Sardis who purchased Heracles as a slave for three years (Apollod. 2.6.3) or one year (Diod. Sic. 4.31.5–8) as atonement-service imposed by the Delphic Oracle for the murder of Iphitos. During servitude, the canonical gender-inversion episode: Heracles spun wool while Omphale wore his Nemean-lion-skin and wielded his club (Ovid Heroides 9.55–118; Lucian Dial. Deor. 13). Bore Heracles three sons in some recensions — Lamos, Agelaos, and Tyrrhenos (the eponymous Tyrrhenian-Etruscan migration-figure per Hdt. 1.94, the canonical-Roman pseudo-genealogical anchor of the Lydian-to-Etruscan migration). Daughter of Iardanos; widow of Tmolos. The Heracles-spinning-wool tableau became one of the most-iconographically-developed episodes of the Heracles cycle in Hellenistic-and-Roman art (mosaics at Liria; the Farnese marble group in Naples).
