Atreus

Atreus, the legendary king of Mycenae, who succeeded his father, Pelops, married Aerope, and was the father of Agamemnon and Menelaus. To avenge the seduction of his wife by his brother, Thyestes, he killed the children of the latter, and served up their corpses at a banquet given to their father. AEgisthus, another son of Thyestes, killed Atreus, and the Nemesis attaching to the house extended to later generations. Sophocles made Atreus the subject of a tragedy which is no longer extant.
