Orestes was the son of Agamemnon who avenges his father by killing Clytemnestra and Aegisthus. His pursuit by the Furies and eventual trial transform a cycle of family revenge into a story about law, judgement and civic order.
Aeschylus’s Oresteia gives the most influential account of Orestes’ revenge and its consequences. After killing his mother, he is pursued by the Erinyes until Athena establishes a trial at Athens, replacing private blood vengeance with civic judgement.
In Susan C Wilson’s Clytemnestra’s Bind, before Clytemnestra becomes queen of Mycenae, Agamemnon seizes her home, kills her first husband Tantalus and their infant son, and forces her into marriage. She enters the House of Atreus as both captive and political prize, surrounded by a dynasty whose history of violence is treated as inheritance. Survival requires her to understand Agamemnon’s ambition while building a life around the children born from the marriage: Iphigenia, Electra and Orestes. Clytemnestra attempts to protect her household from the rivalries linking Mycenae, Sparta and Troy, but the marriages and desires of the younger generation give Agamemnon the opportunity for war he has been seeking. Henry Treece’s Electra survives inside the victorious household, preserving the memory of her father while waiting for her exiled brother Orestes. Further fictional perspectives on Orestes can be found in Euripides’ Electra and Other Plays, Euripides’ Orestes and Other Plays, Euripides’ The Bacchae and Other Plays, Costanza Casati’s Clytemnestra, and Homer’s The Iliad.
