Agamemnon
The play Agamemnon (Agamemnon, Agamemnon) details the homecoming of Agamemnon, King of Argos, from the Trojan War. Waiting at home for him is his wife, Clytemnestra, who has been planning his murder, partly as revenge for the sacrifice of their daughter, Iphigenia, & partly because in the ten years of Agamemnon's absence she's entered into an adulterous relationship with Aegisthus, Agamemnon's cousin & the sole survivor of a dispossessed branch of the family, who is determined to regain the throne he believes should rightfully belong to him.
