Oresteia

The Oresteia (Ancient Greek: Ὀρέστεια) is a trilogy of Greek tragedies written by Aeschylus concerning the end of the curse on the House of Atreus. The name derives from the character Orestes, who sets out to avenge his father's murder.

The only extant example of an ancient Greek theater trilogy, the Oresteia won first prize at the Dionysia festival in 458 BC. When originally performed, it was accompanied by Proteus, a satyr play that would have followed the trilogy. Proteus has not survived, however. In all likelihood the term "Oresteia" originally referred to all four plays; today it generally designates only the surviving trilogy.
