Agamemnon Summary

Aeschylus' Agamemnon is a classical Greek tragic drama, written in Greece and first performed around 458 BCE. Set in the city of Argos, outside the royal house of Atreus, the play belongs to the literary period of Classical Greek tragedy. The narrative reaches its climax when Clytemnestra murders Agamemnon, making her the central antagonist of the play.

Summary

The play Agamemnon begins with a Watchman on the roof of the palace in Argos. He has been keeping watch for a year, waiting for a signal fire that will announce the Greek victory in the Trojan War. Queen Clytemnestra ordered him to stay alert for this sign. The Watchman prays for his job to be over soon and hints at dark events happening in the palace.

Suddenly, the signal fire appears, and the Watchman excitedly runs to tell Clytemnestra that Troy has fallen. However, his joy quickly fades, and he expresses unease about the situation in the royal family. His fear hints at the curse on the House of Atreus, a family plagued by violence and revenge.

The Chorus, made up of old men of Argos, enters and explains the background of the war. The Trojan War began when Prince Paris of Troy took Helen, the wife of Menelaus. To get her back, Menelaus and his brother Agamemnon gathered an army and attacked Troy. The Chorus emphasizes that revenge is at the heart of the conflict.

They also recount how the goddess Artemis delayed Agamemnon’s fleet with strong winds. To appease her, Agamemnon sacrificed his daughter Iphigenia. This act of sacrifice and revenge set off a chain of tragic events.

Clytemnestra enters, and the Chorus asks her for news. She confirms that Troy has been destroyed, but the Chorus doubts her, showing how women’s words were often questioned in Greek society. She explains how the signal fires were used to pass the news and describes the situation in Troy—while the Greeks celebrate, the Trojans mourn. However, she warns that if the Greek army behaves poorly, the gods may punish them. Before leaving, she reminds everyone that disaster can strike at any moment, possibly hinting at her own secret plans. The Chorus, impressed by her words, comments that she speaks wisely—like a man.

The Chorus praises Zeus for destroying Troy and sees it as proof that the gods interfere in human affairs. They believe Zeus punished Paris for his arrogance in stealing Helen from Menelaus. However, the Chorus is also worried about the heavy Greek losses in the war, fearing unrest in Argos and resentment toward Agamemnon. They caution that excessive pride and violence could anger the gods, drawing a comparison between Paris and Agamemnon. They also suggest that Agamemnon’s return may not be politically smooth.

A Herald arrives, joyfully thanking the gods for his safe return and confirming that Troy has fallen and Agamemnon is coming home. He acknowledges both the gods who helped the Greeks and those who opposed them, hoping all will now favor them. His speech reinforces the belief that fate is controlled by the gods, making it essential to keep them pleased.

The Chorus, anxious about potential troubles in Argos, tells the Herald that the army is welcome. When the Herald asks if they feared anyone in Agamemnon’s absence, they admit they did but refuse to name the person. This hints at their concern about Clytemnestra and how she ruled in Agamemnon’s absence, as well as possible violence ahead.

The Herald, focused on celebrating victory, tells the Chorus not to dwell on past hardships. He speaks of his own struggles and survival, but his patriotic optimism blinds him to the possibility that the gods may not favor Agamemnon or the war’s outcome. He does not recognize the ongoing cycle of revenge and violence.

Clytemnestra enters, scolding the Chorus for doubting her earlier news of Troy’s fall. She boasts that the people of Argos believed her and then expresses joy at her husband’s return, claiming to have been a loyal and loving wife. However, her words seem to be part of a calculated act, hiding her true intentions. The fact that the citizens trusted her suggests she has gained influence in Agamemnon’s absence.

The Chorus asks about Menelaus’ fleet, and the Herald reveals that a storm struck during their return, leaving Menelaus and his men missing. He avoids spreading bad news without confirmation and then departs. His belief that his fleet survived due to divine favor, while ignoring the possibility of greater consequences, adds dramatic irony to the unfolding tragedy.

The Chorus reflects on Helen, blaming her for the war and Troy’s destruction. They describe how she traveled to Troy by boat, followed by Agamemnon’s army, which led to the city’s downfall. This foreshadows the violence about to unfold in Argos, reinforcing the theme of fate and the never-ending cycle of destruction.

Finally, the Chorus states that violent and evil deeds only lead to more violence. They argue that true fulfillment comes from righteousness and rejecting the pursuit of power and luxury. This warning comes just before Agamemnon makes a mistake that continues the cycle of revenge.

Agamemnon enters the stage in a grand display, riding a chariot with Cassandra, a Trojan princess and his war prize. By taking her as a concubine, he shows Troy’s complete defeat. However, this display of power and wealth comes right after the Chorus warns against arrogance.

The Chorus welcomes Agamemnon and speaks honestly. They say that while not everyone agrees with his choices—especially sacrificing his daughter—they are glad he is back. However, they hint that not everything is well at home. Their words show both loyalty and a warning, as deceit lurks in Argos, including within Agamemnon’s own household.

Agamemnon thanks the gods for his victory but also complains that the war started over a woman. His speech is proud and boastful, and while he promises to address any unrest in Argos, his tone suggests arrogance. The play’s themes of war, fate, and gender roles become more evident, and there is a growing sense that Agamemnon may not get the chance to fix the problems the war caused.

As Agamemnon steps down from his chariot, Clytemnestra stops him and speaks to the crowd. She describes her suffering while he was away, saying she even had suicidal thoughts. She explains that she sent their son, Orestes, away for his safety. Then, as a way to honor Agamemnon, she urges him to walk on a luxurious purple carpet into the palace.

Clytemnestra’s sweet and submissive tone is part of her act to carry out her revenge. Walking on the carpet would be a sign of arrogance, offending the gods and sealing Agamemnon’s fate. She also mentions Orestes, who will return later to end the cycle of revenge.

At first, Agamemnon refuses to walk on the carpet, saying it would be disrespectful to the gods. However, Clytemnestra keeps pressuring him, and he eventually gives in, walking into the palace on the tapestries. She continues acting as a loving wife and prays to Zeus, but her true intentions are clear—she is setting the stage for Agamemnon’s downfall.

The Chorus, despite seeing Agamemnon return safely, still feels uneasy. They sense that fate is about to take a dark turn and that something terrible will happen. Their words reinforce the play’s ominous mood, foreshadowing the tragedy ahead.

Clytemnestra comes out of the palace and orders Cassandra to get down from the chariot and go inside, but Cassandra stays silent. At first, Clytemnestra tries to persuade her, and the Chorus encourages Cassandra to obey, saying that fate has brought her here. But as Cassandra continues to say nothing, they begin to wonder if she is mute, insane, or needs someone to translate for her. Eventually, Clytemnestra grows frustrated, gives up, and goes back into the palace.

Whether or not Clytemnestra originally planned for Cassandra to be part of her revenge, she now wants to make sure Cassandra does not interfere. Both women are breaking traditional gender roles—Clytemnestra by giving orders, and Cassandra by ignoring them. In the end, both will suffer for going against society’s expectations.

The Chorus gathers around Cassandra as she falls into a trance. She starts speaking in disconnected phrases, which gradually turn into a prophecy. She describes a vision of children being cooked and eaten. This refers to a past crime in Agamemnon’s family, when his father, Atreus, killed his brother’s children and fed them to him. This act of cruelty set off the chain of revenge that continues in the play.

Next, Cassandra sees a vision of a woman bathing a man and then killing him inside the palace. She senses that the Furies, divine spirits of vengeance, are at work. She then realizes that she herself will be the next victim. Even though her words are unclear, she seems to accept her fate, confirming that the cycle of violence will continue.

The Chorus asks Cassandra how she became a prophet. She reveals that the god Apollo fell in love with her, but when she refused to have his child, he cursed her. As punishment, she would always tell the truth, but no one would ever believe her. This is yet another example of a woman being punished for refusing to follow society’s rules.

Cassandra then returns to her earlier vision of a man being tricked into eating his own children (Agamemnon’s uncle, Thyestes). Finally, she clearly states that Agamemnon will be murdered. However, the Chorus does not understand how this past crime connects to the present danger. Since the original Greek audience knew the full story, their failure to grasp the prophecy creates a strong sense of dramatic irony.

The Chorus asks who could possibly kill the king, unable to imagine that a woman could commit such an act. Frustrated, Cassandra gives up on trying to explain her vision. Their disbelief is rooted in gender bias—they do not suspect Clytemnestra, even though she is right in front of them.

In a final, desperate moment, Cassandra tears her clothes and predicts that a man will come, kill his mother, and finally end the cycle of revenge in Agamemnon’s family. This foreshadows the next play in the trilogy, where Orestes, Agamemnon’s son, returns to kill Clytemnestra. Knowing that she cannot escape her fate, Cassandra accepts her death and enters the palace, fully aware of the terrible end that awaits her.

The Chorus thinks about Cassandra’s prophecy. They realize that if Agamemnon could win a war with the gods’ help but still be killed because of a crime his father committed long ago, then life must truly be controlled by fate. This moment is full of suspense, as the audience knows what will happen next, but the characters are still catching up.

Suddenly, Agamemnon screams twice from inside the palace. The Chorus panics, and different members suggest different actions, creating a sense of chaos before the big reveal.

The palace doors open, and Clytemnestra stands there, covered in blood, with the dead bodies of Agamemnon and Cassandra behind her. She admits to the murders and describes how she stabbed Agamemnon twice. The Chorus wants her exiled, but she argues that they are being unfair—after all, they did not call for Agamemnon to be punished when he sacrificed their daughter, Iphigenia.

For Clytemnestra, killing Agamemnon was an act of revenge for Iphigenia’s death. But the Chorus’s reaction shows how society views men and women differently—Agamemnon’s killing of his daughter was tolerated, while Clytemnestra’s revenge is condemned.

The Chorus calls Clytemnestra arrogant, but she ignores them and reveals that she is in love with Agamemnon’s cousin, Aegisthus. She claims that Agamemnon was unfaithful and cruel, while Aegisthus is loyal. She insists that Agamemnon and Cassandra deserved to die. However, this revelation complicates her revenge, as she has also been unfaithful.

The Chorus mourns the tragedy and blames all the destruction on women, linking Clytemnestra’s actions to Helen, who they believe caused the Trojan War. Clytemnestra defends Helen, pointing out that she didn’t personally kill anyone. But the Chorus continues to criticize both women for not behaving as they believe women should.

Clytemnestra refuses to feel guilty for the murders, but the Chorus warns that she is now part of the curse that haunts Agamemnon’s family. They wonder how the cycle of revenge can ever end, as each act of violence leads to another. This foreshadows the next play in the trilogy, where Agamemnon’s son, Orestes, will return to take revenge.

Aegisthus enters with his soldiers and celebrates Agamemnon’s death. He reminds everyone of the past crime that started this cycle—Agamemnon’s father, Atreus, killed Aegisthus’ brothers and tricked their father, Thyestes, into eating them. The Chorus insults Aegisthus, calling him weak and cowardly for not fighting in the war and for letting Clytemnestra carry out the murder.

Aegisthus threatens the Chorus, but Clytemnestra prevents further violence. She and Aegisthus go back into the palace together, while the Chorus stays behind, praying for Orestes to return and bring peace to the House of Atreus. The play ends in political turmoil, leaving the story open for the next part of the trilogy.

Themes Analysis

Fate

In Agamemnon, fate is like an unbreakable net—no one can escape it. The characters are caught in their destinies, unable to change the course of their lives. But if everything is already decided, can anyone truly be blamed for their actions?

Clytaemnestra kills her husband, but is it really her choice, or just part of the curse on her family? Agamemnon leads soldiers to war, but is he responsible, or is Zeus pulling the strings? The Chorus—the play’s voice of reason—believes that no matter what fate has in store, people still have to answer for their actions. Fate isn’t just about destiny—it’s also about paying for the wrongs you commit.

The gods—Zeus, Apollo, Artemis, and Ares—are like unseen puppeteers, twisting events in ways humans can’t control. They stir up storms, place curses, and turn people’s lives upside down. But the real mystery is free will: do humans make their own choices, or are they just following a script written by the gods? The gods may already know what will happen, but people act without knowing their fate. And whether or not they are in control, they must face the consequences of their deeds.

Revenge vs. Justice

In Agamemnon, revenge isn’t just an impulse—it’s a rule, an ancient way of settling scores. If someone wrongs you or your family, you strike back. Blood demands blood.

Agamemnon’s family is cursed by a cycle of vengeance. Long before the play begins, Thyestes curses the House of Atreus, ensuring that its members will keep killing each other. Agamemnon’s murder is just the latest chapter: Aegisthus wants revenge for his murdered siblings, and Clytaemnestra believes she is simply punishing Agamemnon for sacrificing their daughter, Iphigenia. But vengeance never stops—it keeps spinning like a wheel. By the play’s end, we sense that Clytaemnestra, too, will fall to the same bloody pattern.

To Clytaemnestra and Agamemnon, justice means revenge. The war against Troy is justice for Helen’s abduction. Agamemnon’s death is justice for Iphigenia. But the Chorus sees justice differently. They believe people should be punished or rewarded based on their own actions, not their family’s history. To them, justice is about fairness—not just settling old grudges.

Justice also has a bigger, political side. Agamemnon, as a king, should protect his people, but his choices bring suffering, even in victory. The Chorus warns Aegisthus that the people of Argos won’t accept his rule just because he took revenge. True justice isn’t about personal payback—it’s about protecting and leading a community.

Righteousness vs. Evil

"Doing good leads to good things," the Chorus says—but in Agamemnon, what is good and what is evil?

Agamemnon believes he is righteous for leading the Greeks to war. Clytaemnestra believes she is righteous for killing him. But those who suffer from their choices see them as wicked. The play is full of this contradiction—characters see themselves as heroes, but others see them as villains.

One of the play’s biggest questions is: does justice become evil when it’s carried out by an individual rather than a society? Some believe Agamemnon is part of a bigger story about civilization. In this first play of the Oresteia trilogy, justice is personal and violent. But as the story continues, justice will shift from blood feuds to a court of law, marking the change from chaos to order.
