Set in Argos before the royal palace, Agamemnon concerns the return of Agamemnon, King of Argos, from the Trojan War and his eventual death at the hand of his wife, Clytemnestra. While pretending to love him, she is secretly furious that he has sacrificed their daughter, Iphigenia. Further, Agamemnon has brought a slave and concubine, the prophetess Cassandra. Eventually, Clytemnestra murders Agamemnon in the bath. As with animal sacrifices, she hacks him with three strokes of a pelekus (a doubleheaded axe).
