The Oresteia Duology by the ancient Greek playwright Aeschylus consists of the two linked plays Agamemnon and The Libation Bearers . Agamemnon describes the homecoming of King Agamemnon of Argos from the Trojan War, along with his concubine Cassandra. His wife, Clytemnestra, however, had long been planning his murder (in concert with her lover, Aegisthus) as revenge for Agamemnon’s earlier sacrifice of their daughter, Iphigenia. The Libation Bearers deals with the reunion of Agamemnon's children, Electra and Orestes, and their revenge as they kill Clytemnestra and Aegisthus in a new chapter of the curse of the House of Atreus.
