This shows the contest of Pelops with Oinomaos, King of Pisa, for the hand of his daughter Hippodameia. An oracle is said to have told the King that his son-in-law would murder him, so he challenged each suitor to a chariot race-to-the-death, from Olympia to Corinth. Since Oinomaos' horses were divine the outcome was a foregone conclusion and the loser was killed - all except Pelops who succeeded either by cheating or by the gift of swifter horses from Poseidon.
