Oenomaus

King of Pisa and son of Ares, he drove horses his father gave him, said to be swifter than the wind.

Warned by an oracle that he would die at his son-in-law's hand, he challenged every suitor of his daughter Hippodamia to a chariot race, ran them down, and killed them. No chariot could beat the horses of Ares, so the race was in effect an execution.

Myrtilus, his charioteer, bribed by Pelops, swapped the chariot's linchpins for wax, and the king fell to his death from the shattering chariot. Dying, he cursed Myrtilus to die at Pelops's hand — and that curse alone came true with an oracle's precision.

A man who tries to escape an oracle hastens it with his own hands — exactly the same structure as Acrisius and his bronze chamber.
