Agamemnon by Aeschylus

FCK.School cheat sheet, fck.school/books/agamemnon

1-minute snapshot

Agamemnon returns home from Troy after ten years of war. His wife Clytemnestra has been waiting, and not patiently. She kills him in his bath, avenging the sacrifice of their daughter Iphigenia and settling a score she has nursed for a decade. The play is the first part of the Oresteia trilogy. It sets up a cycle of violence inside the house of Atreus, where every act of justice creates a new crime that demands another response.

Key takeaways

  • Clytemnestra drives the plot. She is not a passive villain. She planned the murder, executed it, and defended it publicly. Every scene she is in, she controls.
  • The house of Atreus carries a curse. The violence did not start with Agamemnon. His father's crimes set off a chain of revenge killings that the play keeps referencing. This family cannot escape its own history.
  • Cassandra is the moral center. She sees the truth, says it clearly, and no one listens. Her scene shows how prophecy works as tragedy: knowing what is coming does not help you stop it.
  • Pride makes Agamemnon killable. Walking on the purple robes is the moment Agamemnon crosses a line. He knows it is wrong and does it anyway. Clytemnestra uses his ego against him.
  • Justice and revenge look identical here. Clytemnestra frames murder as justice. Aegisthus does the same. The play does not let you easily separate the two, which is the problem the rest of the trilogy has to solve.

Themes

  • Revenge cycles that never resolve. Every act of violence in the play is framed as payback for a previous one. Clytemnestra kills Agamemnon for Iphigenia. Aegisthus claims his own grievance. The chorus warns Orestes will come. No one breaks the pattern, and the play does not pretend anyone will.
  • Pride as a path to destruction. Agamemnon's willingness to walk on the purple robes shows how pride works in this play: it does not announce itself, it just makes you do things you know are wrong. The gods punish this kind of overreach, and Clytemnestra uses it as a weapon.
  • The failure of prophecy to prevent disaster. Cassandra knows exactly what will happen and says so. It changes nothing. Aeschylus uses her to show that knowledge without power or belief is useless. Tragedy happens not because people are ignorant but because they cannot act on what they know.
  • Gender and power. Clytemnestra holds power in a world that does not expect women to. The chorus is repeatedly unsettled by her authority. She uses flattery, manipulation, and finally violence to get what she wants. The play watches her do it without fully condemning or praising her.
  • The weight of inherited guilt. The house of Atreus is already cursed before the play begins. Agamemnon inherits crimes he did not commit. His children will inherit his. Aeschylus treats family history as something inescapable, a force that shapes what people do even when they try to choose differently.

Characters

  • Clytemnestra. Queen of Argos and the play's real protagonist. She planned Agamemnon's murder over ten years, executed it herself, and defended it publicly. She is intelligent, controlled, and completely without remorse. Every scene she is in, she is the most powerful person in it.
  • Agamemnon. King of Argos and commander of the Greek forces at Troy. He returns victorious but walks into a trap. His willingness to sacrifice Iphigenia and his pride in accepting the purple robes both contribute to his death. He is on stage briefly but his choices drive the whole plot.
  • Cassandra. A Trojan princess taken by Agamemnon as a war prize. She has the gift of prophecy from Apollo, paired with the curse that no one believes her. She sees the murders coming, describes them to the chorus, and walks into the palace knowing she will die. Her scene is the emotional peak of the play.
  • Aegisthus. Clytemnestra's lover and co-conspirator. He claims the murder was justice for crimes Agamemnon's father committed against his family. The chorus treats him with contempt because he let a woman do the killing. He is politically ambitious but morally weak compared to Clytemnestra.
  • The Chorus of Argive Elders. Old men of Argos who represent the community. They know something is wrong, they half-understand Cassandra's visions, and they cannot act. They provide historical context, moral commentary, and a record of how ordinary people respond when power turns violent.
  • The Watchman. Opens the play from the palace roof. He is relieved the war is over but signals that the household is troubled. His brief scene sets the tone: something is being waited for, and it will not be good.
  • The Herald. Arrives before Agamemnon to announce the victory. He also reports the storm that destroyed much of the fleet. His scene grounds the play in the real cost of the war before the domestic tragedy takes over.
