Featured in ancient Greek literature, from poems to plays, the Erinyes form the Chorus and play a major role in the conclusion of Aeschylus's dramatic trilogy the Oresteia. In the first play, Agamemnon, King Agamemnon returns home from the Trojan War, where he is slain by his wife, Clytemnestra, who wants vengeance for her daughter Iphigenia, who was sacrificed by Agamemnon in order to obtain favorable winds to sail to Troy. In the second play, The Libation Bearers, their son Orestes has reached manhood and has been commanded by Apollo's oracle to avenge his father's murder at his mother's hand.
