Editing Aida (section)

===Act 2===
''Scene 1: The chamber of Amneris''

Dances and music to celebrate Radamès' victory take place (Chorus, Amneris: "Chi mai fra gli inni e i plausi" / Our songs his glory praising). However, Amneris is still in doubt about Radamès' love and wonders whether Aida is in love with him. She tries to forget her doubt, entertaining her worried heart with the dance of [[Moorish]] slaves (Chorus, Amneris: "Vieni: sul crin ti piovano" / Come bind your flowing tresses).

When Aida enters the chamber, Amneris asks everyone to leave. By falsely telling Aida that Radamès has died in the battle, she tricks her into professing her love for him. In grief, and shocked by the news, Aida confesses that her heart belongs to Radamès eternally (Amneris, Aida: "Fu la sorte dell'armi a' tuoi funesta" / The battle's outcome was cruel for your people).

This confession fires Amneris with rage, and she plans on taking revenge on Aida. Ignoring Aida's pleadings (Amneris, Aida, chorus: "Su! del Nilo al sacro lido" / Up! at the sacred shores of the Nile), Amneris leaves her alone in the chamber.

''Scene 2: The grand gate of the city of Thebes''

Radamès returns victorious and the troops [[Triumphal march|march]] into the city (Chorus, Ramfis: "Gloria all'Egitto, ad Iside" / Glory to Egypt, [and] to Isis!).

The Egyptian king decrees that on this day the triumphant Radamès may have anything he wishes. The Ethiopian captives are led onstage in chains, Amonasro among them. Aida immediately rushes to her father, who whispers to her to conceal his true identity as King of Ethiopia from the Egyptians. Amonasro deceptively proclaims to the Egyptians that the Ethiopian king (referring to himself) has been slain in battle. Aida, Amonasro, and the captured Ethiopians plead with the Egyptian King for mercy, but Ramfis and the Egyptian priests call for their death (Aida, Amneris, Radamès, The King, Amonasro, chorus: "Che veggo! .. Egli? .. Mio padre! .. Anch'io pugnai .. Struggi, o Re, queste ciurme feroci" / What do I see?.. Is it he? My father? .. Destroy, O King, these ferocious creatures).

Claiming the reward promised by the King of Egypt, Radamès pleads with him to spare the lives of the prisoners and to set them free. The King grants Radamès' wish, and declares that he (Radamès) will be his (the King's) successor and will marry the King's daughter (Amneris). (Aida, Amneris, Radamès, Ramfis, The King, Amonasro, chorus: "O Re: pei sacri Numi! .. Gloria all'Egitto" / O King, by the sacred gods ... Glory to Egypt!). At Ramfis' suggestion to the King, Aida and Amonasro remain as hostages to ensure that the Ethiopians do not avenge their defeat.
