Sterope, in Grecian mythology, was —
1. A Pleiad, the wife or mother of OEnomaus (Apollod. 3, 10,1) and daughter of Atlas (Paus. 5, 10, 5).
2. Daughter of Pleuron and Xantippe, and sister of Agenor and Leophontes (Apollod. 1, 7, 7).
3. Daughter of Cepheus of Tegea. Her father declined to join Hercules in the war against the Hippocoontides, because he feared an invasion of the Argives during his absence. Hercules thereupon gave to Sterope a brazen lock of Medusa's hair, which he had himself obtained from Minerva. This, displayed in the face of an advancing foe, would transform every warrior into stone. Cephemus was thus induced to join in a war in which he and his twenty sons lost their lives (Apollod. 2, 7, 3).
4. A daughter of Acastus, whose career is interwoven with the history of Peleus (Apollod. 3, 13, 3).
5. A daughter of Porthaon, and mother of the Sirens (Apollod. 1, 7,10).
