Full Summary

Early Life in Sparta

Clytemnestra grows up in the brutal Spartan court, where she learns to hunt, fight, and endure punishment. Her sister Helen is both her closest companion and a source of rivalry. When the wealthy Tantalus of Maeonia visits, Clytemnestra falls in love and marries him, bearing a son. But Agamemnon and Menelaus, exiled sons of Atreus, arrive in Sparta. Agamemnon becomes obsessed with Clytemnestra. He and Menelaus plot against Tantalus; with the complicity of Tyndareus, they murder Tantalus and the baby. Clytemnestra is forced to marry Agamemnon, cursing her father and swearing vengeance by the Furies.

Life in Mycenae and the Sacrifice of Iphigenia

In Mycenae, Clytemnestra endures Agamemnon’s brutality—including rape—but slowly asserts her authority. She bears him four children: Iphigenia, Electra, Chrysothemis, and Orestes. When the Trojan War begins, Agamemnon lures Clytemnestra to Aulis under the pretense of marrying Iphigenia to Achilles. Instead, he sacrifices her to appease Artemis. Clytemnestra is knocked unconscious trying to save her daughter. For nine years she grieves and nurtures revenge against Agamemnon, Odysseus, Diomedes, and the seer Calchas.

The Years of Rule and the Affair with Aegisthus

Clytemnestra rules Mycenae competently, commanding merchants and elders. She trains her children harshly. Aegisthus, son of Thyestes, arrives as a stranger; she recognizes him and keeps him close. They become lovers, and she executes two elders who plot to replace her with Orestes. She sends Orestes to Sparta to marry Hermione, securing alliances. When the beacon signals Troy’s fall, she and Aegisthus plan to murder Agamemnon. She publicly arrests Aegisthus to deceive the elders.

The Murder of Agamemnon and Aftermath

Agamemnon returns with the slave Cassandra. At a feast, Calchas taunts Clytemnestra by praising Iphigenia’s sacrifice. Clytemnestra kills Calchas in the temple, then confronts Agamemnon in the bath. After a struggle, she stabs him repeatedly, declaring that he never knew loyalty. Aegisthus kills Cassandra. Electra discovers her father’s body and weeps. Clytemnestra confesses to the murder in the dining hall, recounting Agamemnon’s crimes. The warriors accept her as queen. Electra rejects her mother, swearing that Orestes will return to avenge his father. Clytemnestra learns that Helen is alive and reconciled with Menelaus. She accepts that her story will be distorted by legend, but holds to the truth of her vengeance.
