Amonasro

Aida and Amonasro remain as hostages to ensure that the Ethiopians do not avenge their defeat.

Aida, who is also secretly in love with Radamès, is the captured daughter of the Nubian King Amonasro, but her Egyptian captors are unaware of her true identity.

Amonasro and Aida try to convince Radamès to escape with them, but he refuses and surrenders to the imperial guards.

Amonasro declares that the Nubian king (he himself) has been slain in battle.

When he arrives, Amonasro hides behind a rock and listens to their conversation.
