Caesar and Antony try to make amends through the marriage of Antony to Caesar's sister Octavia. Antony soon deserts Octavia, however, and returns to live with Cleopatra. Caesar, enraged, vows to attack and regain control of Egypt from Antony and Cleopatra. Caesar's army is more powerful and more skillful, and soon approaches defeat of Antony. Antony, facing defeat, asks Eros (another friend) to kill him. Eros cannot, and instead kills himself. Antony then kills himself by falling on his sword. Cleopatra, in grief over Antony's death and determined never to fall under Caesar's command commits suicide by allowing poisonous asps to bite her.
