The dramatic trilogy The Oresteia is Aeschylus's way of telling readers that mankind cannot hope to build a progressive society if there is a constant need for revenge. The author, Aeschylus, suggests that the way out of this downward spiral to anarchy is one in which there is the rule of law, not the code of personal honor and revenge.
Queen Clytemnestra thinks that she has brought justice to Argos when she murders Agamemnon and his captive Cassandra.

Rather than hoping for peace in Argos, another family member, Electra, hates both her mother Clytaemnestra and her mother's lover Aegisthus. Electra prays for violent and unpitying revenge for the death of her father.
