Oenomaeus' mother was either naiadHarpina or Sterope, one of the Pleiades, whom some identify as his consort instead. He married, if not Sterope, then Evarete of Argos, the daughter of Acrisius and Eurydice. Yet others give Eurythoe, daughter of Danaus, either as his mother or consort. His children besides Hippodamia were Leucippus and Alcippe. Pausanias, who is generally skeptical about stories of humans descending from gods, makes Oenomaus son of a mortal father, Alxion. John Tzetzes adduces a version which, in the same vein, calls Oenomaus son of a Hyperochus by Sterope. The genealogy offered in the earliest literary reference, Euripides' Iphigenia in Tauris, would place him two generations before the Trojan War, making him the great-grandfather of the Atreides, Agamemnon and Menelaus.
Mythology
Courtship of Hippodamia
King Oenomaus, fearful of a prophecy that claimed he would be killed by his son-in-law, had killed eighteen suitors of his daughter Hippodamia after defeating them in a chariot race. He affixed their heads to the wooden columns of his palace. Pausanias was shown what was purportedly the last standing column in the late second century CE; he mentions that Pelops erected a monument in honor of all the suitors who preceded him, and lists their names:
son of King Tantalus of Lydia, came to ask for her hand and prepared to race Oenomaus. Worried about losing, Pelops went to the seaside and invoked Poseidon, his former lover. Reminding Poseidon of their love, he asked Poseidon for help. Smiling, Poseidon caused a chariot drawn by winged horses to appear. Pelops and Hippodamia, very much in love, devised a plan to replace the bronze linchpins attaching the wheels to the chariot axle with fake ones made of beeswax. The race began, and went on for a long time. But just as Oenomaus was catching up to Pelops and readying to kill him, the wheels flew off and the chariot broke apart. Oenomaus' charioteer, Myrtilus, survived, but Oenomaus was dragged to death by his horses. Pelops then killed Myrtilus after the latter attempted to claim Hippodamia. As Myrtilus died, he cursed Pelops. This was the source of the curse that haunted descendants of Pelops', including Atreus, Thyestes, Agamemnon, Aegisthus, Menelaus and Orestes. Also, the burial place of Myrtilus was a taraxippus in Olympia, a "horse-frightening place" during races. In memory of Oenomaus, the Olympic Games were created. Oenomaus' chariot race was one legendary origin of the Olympic Games; one of its turning-posts was preserved, and round it grew an Elean legend of a burnt "house of Oenomaus", reported by Pausanias in the 2nd century CE.
