"The Eumenides" is the third play in the Oresteia trilogy by the ancient Greek playwright Aeschylus. It follows the story of Orestes, who is pursued by the Furies after avenging his father's murder by killing his mother, Clytemnestra. The play explores themes of justice, guilt, and the transition from personal vengeance to a more organized legal system. In this play, Orestes seeks purification and a trial to determine his fate. The goddess Athena intervenes, establishing a court to judge Orestes' actions. The resolution leads to the transformation of the Furies into the Eumenides, symbolizing the shift from vengeance to a more civilized form of justice.
