Core Plot Breakdown

Agamemnon opens with the Greek king’s return to his city after a decade of war in Troy. His wife, Clytemnestra, has waited years to exact revenge for his sacrifice of their daughter Iphigenia, which he made to secure winds for the Greek fleet. The play ends with Clytemnestra murdering Agamemnon and his captive concubine Cassandra, setting up the next two plays in the Oresteia trilogy. Highlight the most consequential plot beat in your notes.

Key Character Motivations

Agamemnon acts out of a sense of duty to his army and the Greek cause, even when it demands personal sacrifice. Clytemnestra acts out of grief for her daughter and a desire to seize political power in the vacuum left by Agamemnon’s long absence. The chorus acts as a moral compass, commenting on events and asking questions about justice and fate. Write one sentence summarizing each character’s core motivation.

Major Themes Explored

The play grapples with the cyclical nature of violence, showing how one act of sacrifice leads to another act of revenge. It also examines the tension between personal grief and political duty, asking whether leaders can prioritize one without betraying the other. Finally, it questions the difference between personal revenge and divine justice. Circle the theme you find most compelling, and jot down one plot event that illustrates it.

Chorus Role Explained

The chorus in Agamemnon is made up of elderly citizens of the city, who observe events and offer commentary. They do not intervene in the action, but their words frame the audience’s understanding of right and wrong, fate and free will. Their perspective shifts as the play progresses, reflecting the uncertainty of the characters’ choices. Note one line of chorus commentary (from class or a study guide) that shapes your interpretation of the play.

Trilogy Context

Agamemnon is the first play in the Oresteia trilogy, which concludes with the trial of Orestes, Agamemnon and Clytemnestra’s son. The full trilogy explores the transition from cyclical revenge to a system of formal justice. Understanding this context is critical to interpreting Agamemnon’s unresolved ending. Add one note to your study guide linking Agamemnon’s ending to the trilogy’s overall message.

Class Discussion Prep

Use this before class: Come prepared with one specific plot event, one character motivation, and one thematic question. Tie your question to a real-world example, such as debates over accountability for wartime choices. Practice explaining your question out loud to ensure it’s clear and engaging. Write your question and supporting example on an index card to bring to class.
