Thyestes

In Greek mythology, Thyestes (pronounced , , ) was the son of Pelops and Hippodamia, King of Olympia, and father of Pelopia and Aegisthus. Thyestes and his brother, Atreus, were exiled by their father for having murdered their half-brother, Chrysippus, in their desire for the throne of Olympia. They took refuge in Mycenae, where they ascended the throne upon the absence of King Eurystheus, who was fighting the Heracleidae. Eurystheus had meant for their lordship to be temporary; it became permanent because of his death in conflict.
