 The same myth is told differently by Sophocles and Euripides in their "Electra" plays.The story of Orestes was the subject of the "Oresteia" of Aeschylus ("Agamemnon", "Choephori", "Eumenides"), of the "Electra" of Sophocles, and of the "Electra", "Iphigeneia in Tauris", "Iphigenia at Aulis" and "Orestes", all of Euripides.In Aeschylus's "Eumenides", Orestes goes mad after the deed and is pursued by the Erinyes, whose duty it is to punish any violation of the ties of family piety.
