Mythical king of Pisa near Olympia. He was warned by an oracle that he would die at the hands of his son-in-law, and therefore wished to prevent his daughter from ever marrying. He was an outstanding charioteer, and promised his daughter's hand to the man who could defeat him in a chariot race, thinking that this could never happen. After many suitors had failed this test, Pelops succeeded, but only by sabotaging Oinomaos' chariot.
