In Greek mythology, Thyestes (pronounced , , ) was the son of Pelops and Hippodamia. He was a 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.
The most popular representation of Thyestes is that of the play Thyestes by Seneca in 62 C.E. This play is one of the originals for the revenge tragedy genre. Although inspired by Greek mythology and legend, Seneca's version is different. __TOC__
Thyestes was an extinct genus of ostracoderm (armored jawless fish) of Europe that lived in the Late Silurian Wenlock epoch. It superficially resembles Cephalaspis, but was closely related to Auchenaspis and Tremataspis.
