Core Plot Breakdown

The play opens with watchmen waiting for Agamemnon’s return from the Trojan War. Clytemnestra has ruled Argos in his absence, plotting revenge for his sacrifice of their daughter. Agamemnon arrives with a captive concubine, and Clytemnestra convinces him to walk on a symbolic carpet into the palace, where she kills him. Use this before class to reference key plot points during discussion. Write down one question you have about Clytemnestra’s choice of murder weapon in your notes.

Character Motivation Deep Dive

Agamemnon’s actions are driven by his duty as a military leader and his desire to maintain his reputation. He views his sacrifice of Iphigenia as a necessary evil to win the war. Clytemnestra’s motivation is rooted in grief and a sense of justice for her daughter’s death; she has spent years planning her revenge. List one way each character’s motivation is revealed through their actions, not just their words, in your study guide.

Symbolic Imagery Explained

The play uses light and darkness to mirror shifts in power and moral clarity. When Agamemnon arrives, light breaks over Argos, symbolizing his return to power. As he enters the palace, darkness falls, foreshadowing his death. The carpet he walks on symbolizes his arrogance and disregard for traditional limits on royal power. Circle two instances of symbolic imagery in your annotated text and write their meaning in the margins.

Trilogy Context

Agamemnon’s ending leaves the house of Atreus in chaos, with Clytemnestra in power and the chorus questioning the morality of her actions. The next two plays in the Oresteia, The Libation Bearers and The Eumenides, follow Orestes, Agamemnon’s son, as he seeks revenge and the gods debate the nature of justice. Write a one-sentence prediction of what Orestes will do next based on the play’s ending.

Class Discussion Prep

Teachers often ask about the chorus’s role because it provides a moral compass for the audience. The chorus questions both Agamemnon’s sacrifice and Clytemnestra’s revenge, reflecting the play’s moral ambiguity. Practice explaining one of the discussion kit’s questions aloud to build confidence for class. Choose a question that asks about moral ambiguity and draft a 2-sentence answer to share.

Essay Writing Tips

Avoid the common mistake of framing Clytemnestra as a purely villainous character; instead, focus on her trauma and the play’s exploration of cyclical violence. Use the essay kit’s thesis templates and outline skeletons to structure your argument with clear textual evidence. Use this before essay drafts to refine your thesis statement and ensure it is arguable, not just descriptive. Revise your thesis to include a specific symbolic device from the play.
