While he was fighting the Trojans, his wife Clytemnestra, enraged by the murder of her daughter, began an affair with Aegisthus. When Agamemnon returned home he brought with him a new concubine, the doomed prophetess, Cassandra. Upon his arrival that evening, before the great banquet she had prepared, Clytemnestra drew a bath for him and when he came out of the bath, she put the royal purple robe on him which had no opening for his head. He was confused and tangled up. Clytemnestra then stabbed him to death.
