The Oresteia is a tragedy in three parts written by Aeschylus in the fifth century BCE. After a decade of warfare, Troy had fallen and Agamemnon, King of Mycenae, returned home. His wife, Queen Clytemnestra, had him killed to avenge the sacrifice of her daughter Iphigenia, to obtain the crown and to marry her lover Aegisthus. This murder leads to further bloodshed when their son Orestes in turn kills Clytemnestra and Aegisthus. The trilogy consists of Agamemnon, The Libation Bearers, and The Eumenides. The Oresteia is the only surviving example of an ancient Greek theatre trilogy and won first prize at the Dionysia festival in 458 BCE.
