The story of Clytemnestra and Agamemnon is told again and again throughout The Odyssey. As you research this relationship/story, try to keep these questions in mind:
1. The Iliad and The Odyssey are set in motion by the sons of Atreus: Agamemnon and Menelaus. There is a curse attached to this family. See if you can discover why they are being punished.
2. Who is Iphegenia? Can you find any representations of her in ancient or modern art? Are there any poems or plays dedicated to or inspired by her?
3. Who were the parents of Clytemnestra? Is her personal history remarkable?
4. Who is the male villain in this story? Does he have any prior cause to envy or resent Agamemnon?
5. Why and how does Clytemnestra take vengeance on her husband?
6. How many times is the story told in The Odyssey? Who tells it - and to whom?
7. Why is it told to Telemachus?
8. Does the murder of Agamemnon signal the end of the story?
9. What roles do Agamemnon's surviving children play?
10. Why is it told so often?
11. Can you find any ancient or modern representations of Agamemnon's murder or of Clytemnestra's fate?

I think that the story of Clytemnestra and Agamemnon is told a lot because it shows the relationship between men and women in the times of the Greeks. It also shows what marraige really is. I bet that before Agamemnon killed Clytemnestra's daughter their marraige was somewhat normal. But Agamemnon sacrificed his own child for the purpose of war: something that infuriated Clytemnestra. She loved and trusted her husband but for him do do something like this was unforgivable. Then, Clytemnestra did something that not many Greek women did, she got back at her husband (by killing him). I also think that this wraps into why this story is told: it shows that women sometimes can have power and are not define by the men that they are married to.
