The Agamemnon:
Before you read the Agamemnon, the first part of the Oresteia, you may need to know a few things that Aeschylus, the author of the play, would have assumed that you already knew.

As you read the Agamemnon, keep in mind that ancient Greek plays marked the ends of scenes with the Chorus (since they didn't have a curtain to lower or lights to dim at the ends of scenes).  At the end of the first scene of the Agamemnon, which is very short, the Chorus comes in and begins to chant.  They are supposed to represent the old men of Argos (who were too old ten years before to go with Agamemnon to fight at Troy).  This first Chorus is very long and difficult (continuing until Clytaemnestra appears on stage), but it's also very important.  Don't worry if you don't understand every word of it.  Just keep in mind that they're having a divinely inspired vision (so that not everything is supposed to make sense or be realistic), and their vision lets them see into the past to know exactly what happened at Aulis ten years before, when Agamemnon sacrificed his daughter Iphigenia (for a synopsis of her story, click here).  Pay close attention to what they say about Agamemnon (whom they call "the king" and "the warlord").  Their vision gives us a lot of insight into the way Agamemnon thinks and acts.

In the Agamemnon, there is considerable conflict between Agamemnon and Clytaemnestra.  She wants to kill him for what he did to their daughter at Aulis, and he wants to stay alive and enjoy his new concubine Cassandra.  But I think that we have to ask ourselves whether there's more to this conflict than just revenge and survival instinct.  What is really at stake here?  Do Agamemnon and Clytaemnestra have conflicting values and conflicting ideas about how things should go?  Why?  What do Agamemnon and Clytaemnestra really want?  What does each of them value most?  How and why are their values coming into conflict?

To help us answer these questions, I recommend that we focus on three areas:

1. What does the Chorus say about what happened at Aulis?  Why does Agamemnon decide to sacrifice his daughter?  What does his decision tell us about what he thinks is important?  Pick out a specific passage that seems to sum up his attitude.
2. When Agamemnon arrives in Argos and is met by Clytaemnestra with the crimson tapestries, how does Agamemnon plan to run things in Argos?  Pick out a specific speech that seems to sum up his plans and attitude.  Does he stick to those plans?
3. In the final scene, what does Clytaemnestra say to justify herself?  What does she plan to do next?  How do you feel about her actions, her justification, and her plans?

Once Orestes has undergone the purification that he came to Delphi for, he escapes the Furies again and flees to Athens, city of Athena, goddess of wisdom and of defensive war.  Once Orestes arrives in Athens, Athena tries to appease the Furies by proposing that Orestes be tried for his crime.  The rest of the play is a reenactment of the trial of Orestes on a hill outside Athens called the Areopagus (the hill on which the Athenians traditionally held their murder trials ever after).  Pay close attention to the various arguments the characters use in the prosecution and defense of Orestes.  What does each side say about how things should be run?  What values does each side espouse?  Pick a speech or two that seem to sum up each side's stance in the trial.

Finally, who (if anyone) wins the conflict that began in the Agamemnon?  What solution does Aeschylus seem to be proposing for the conflict that Agamemnon and Clytaemnestra initiated?  Who benefits from the result of the trial?  Who loses?  Has Agamemnon been vindicated?  Has anything changed at the end of the play?  Have things progressed or regressed?

A great deal has happened before the action of the Oresteia begins.  Ten years before the first play of the trilogy opens, Agamemnon, the king of Argos, was selected leader of the Greek armies that were going to Troy to fight the Trojan War in order to regain Helen (the wife of Agamemnon's brother Menelaus, king of Sparta).  Those armies gathered in an armada of ships at Aulis in Thrace with the intention of sailing together for Troy, but they became stranded at Aulis by contrary winds.  Aulis was without much in the way of resources to feed the multitudes of men in the gathered armies, and the Greeks therefore began to get desperate.  Agamemnon consulted a priest of Artemis, goddess of the hunt and of virginity.  The priest told Agamemnon that he and Menelaus had offended the goddess by killing an animal sacred to her.  In recompense, Agamemnon was told to sacrifice a human virgin to the goddess.  As it happened, the only virgin available at Aulis was Iphigenia, Agamemnon's own daughter, who just happened to be a priestess in a nearby temple.  Agamemnon was therefore faced with a terrible decision:  he must either kill his own daughter in human sacrifice or condemn the Greek armies to remain stranded at Aulis.

He chose to kill his daughter, and the Greek armada sailed safely to Troy.

Clytaemnestra, Agamemnon's wife back home in Argos, was enraged when she heard that her husband had killed their daughter.  For the next ten years, she plotted to kill her husband when he returned from the war.  She even organized an elaborate relay system of bonfires to let her know when Troy falls (so that she could be totally ready for her husband's return).  As soon as Troy is captured by the Greeks (sometimes called Argives or Danaans), a servant of the queen who is waiting on top of a mountain outside the city of Troy will light a bonfire that can be seen from another mountain further away.  There, another servant waits to light another bonfire that can be seen from a mountain even further away from Troy, and so on, and so on, and so on, until the last bonfire on the last mountain can be seen from the roof of the royal palace in Argos itself.  There a servant waits for the bonfire signal to light in order to be able to tell Clytaemnestra the news that Troy has fallen.

That is where the Agamemnon begins.

You may also need a few other bits of useful information.  Agamemnon's father was named Atreus, and Agamemnon and his brother Menelaus are therefore often referred to as the sons of Atreus.  Back in the even more distant past, Atreus had a feud with his brother Thyestes and eventually killed him.  Aegisthus, who has been having an affair with Clytaemnestra during the ten years that Agamemnon has been gone at Troy, is the son of Thyestes and, so, has his own reasons for hating the sons of Atreus.
