Agamemnon:

Aeschylus begins in Greece describing the return of king Agamemnon from his victory in the Trojan War, from the perspective of the towns people (the Chorus) and his wife, Clytemnestra. However dark foreshadowings build to the death of the king at the hands of his wife, who was angry at his sacrifice of their daughter Iphigenia, killed so the Gods would stop a storm hindering the Greek fleet in the war. She was also unhappy at his keeping of the Trojan prophetess Cassandra as a concubine. Cassandra foretells of the murder of Agamenon, and of herself, to the assembled townsfolk, who are horrified. She then enters the palace knowing that she cannot avoid her fate. The ending of the play includes a prediction of the return of Orestes, son of Agamemnon, who will seek to avenge his father.
