Aeschylus' Agamemnon, first produced in 458 BC, is the opening play in his Oresteian trilogy. Agamemnon returns home after the Trojan Wars with his concubine Cassandra and is murdered by his wife Clytemnestra and her lover, Aegisthus. The ensuing blood feud continues until the third and final play, Eumenides, when peace is finally restored to the house of the Atreidae. It is a powerful and moving play which is difficult to interpret and which for a long time lacked an English edition.
