Aeschylus' Oresteia, the only ancient tragic trilogy to survive, is one of the great foundational texts of Western culture. It begins with Agamemnon, which describes Agamemnon's return from the Trojan War and his murder at the hands of his wife Clytemnestra, continues with her murder by their son Orestes in Libation Bearers, and concludes with Orestes' acquittal at a court founded by Athena in Eumenides. The trilogy thus traces the evolution of justice in human society from blood vengeance to the rule of law, Aeschylus' contribution to a Greek legend steeped in murder, adultery, human sacrifice, cannibalism, and endless intrigue.
