The son of Tantalus, a rich king of Lydia who had earned a place at the gods' table. Wanting to test them, Tantalus killed Pelops and served him as a meal to the gods. When they discovered the deed, they punished Tantalos, restored Pelops, and made him a great and beautiful hero. Because Demeter had eaten one of his shoulders, it was replaced by a shoulderblade of ivory.
Pelops managed to win a chariot race against king Oenomaus of Pisa who always won since his horses were those of Ares. By having the king's coachman remove the linchpins of Oenomaus chariot, the princess Hippodameia had sectretly helped him, and her father was dragged to death by the divine horses, curshing the coachman to die by Pelops hand. On his way back, Pelops pushed Myrtilus, the coachman, off the chariot. The dying Myrtilus then cast a curse on Pelops family. Pelops married the princess, and gave the name Peloponessos to the peninsula on which his kingdom lie. The horse races became the origin of the Olympic Games.
Hippodameia gave birth to Thyestes and Atreus, who was the first of the kings of Mycenae, but unfortunately cursed by the charioteer Myrtilus whom Peleus had killed. She also had Dias, Cynosurus, Corinthus, Hippalmus, Hippasus, Cleon, Argeius, Alcanthous, Pittheus, Troezen, Nicippe, Astydameia, Lysidice, Sciron and Epidaurus.
One version tells us that Pelops had a son by a previos wife, Chrysippus. He loved him dearly, and Hippodameia had Atreus and Thyestes kill him out of fear that he would inherit the throne. Pelops then cursed both sons, and Hippodameia committed suicide.
