Works of Aeschylus - Aeschylus [103]
The Oresteia
The most complete tetralogy of Aeschylus' work that still exists is the Oresteia (458 BC), of which only the satyr play is missing. In fact, the Oresteia is the only full trilogy of Greek plays by any playwright that modern scholars have uncovered. The trilogy consists of Agamemnon, The Libation Bearers (Choephoroi), and The Eumenides. Together, these plays tell the bloody story of the family of Agamemnon, King of Argos.
Agamemnon
Agamemnon describes his death at the hands of his wife Clytemnestra, who was angry both at Agamemnon's sacrifice of their daughter Iphigenia and at his keeping the Trojan prophetess Cassandra as a concubine. Cassandra enters the palace even though she knows she will be murdered by Clytemnestra as well, knowing that she cannot avoid her gruesome fate. The ending of the play includes a prediction of the return of Orestes, son of Agamemnon, who will surely avenge his father.
The Libation Bearers
The Libation Bearers continues the tale, opening with Clytemnestra's account of a nightmare in which she gives birth to a snake. She orders Electra, her daughter, to pour libations on Agamemnon's tomb (with the assistance of libation bearers) in hope of making amends. At the tomb, Electra meets Orestes, who has returned from protective exile in Phocis, and they plan revenge upon Clytemnestra and her lover Aegisthus together. They enter the palace pretending to bear news of Orestes' death, and when Clytemnestra calls in Aegisthus to share in the news, Orestes kills them both. Immediately, Orestes is beset by the Furies, who avenge patricide and matricide in Greek mythology.
The Eumenides
The final play of The Eumenides, addresses the question of Orestes' guilt. The Furies pursue Orestes from Argos and into the wilderness. Orestes makes his way to the temple of Apollo and begs him to drive the Furies away. Apollo had encouraged Orestes to kill Clytemnestra, and so bears a portion of the guilt of the act. But the Furies belong to the older race of the Titans, and Apollo is unable to drive them away. He sends Orestes to the temple of Athena, with Hermes as a guide. There, the Furies track him down and, just before he is to be killed, the goddess Athena, patron of Athens, steps in and declares that a trial is necessary.
