The Oresteia (Ancient Greek: Ὀρέστεια) is a trilogy of Greek tragedies written by Aeschylus which concerns the end of the curse on the House of Atreus. When originally performed it was accompanied by Proteus, a satyr play that would have been performed following the trilogy; it has not survived. The term "Oresteia" originally probably referred to all four plays, but today is generally used to designate only the surviving trilogy. "The individual plays probably did not originally have titles of their own"[1] The only surviving example of a trilogy of ancient Greek plays, the Oresteia was originally performed at the Dionysia festival in Athens in 458 BC, where it won first prize. A principal theme of the trilogy is the shift from the practice of personal vendetta to a system of litigation. The name derives from the character Orestes, who sets out to avenge his father after his mother's affair with Aegisthus.
