him. When Florestan learns that the prison he is in belongs to Pizarro, he asks that a message be sent to his wife, Leonore, but Rocco says that it is impossible. Florestan begs for a drop to drink, and Rocco tells Fidelio to give him one. Florestan does not recognize Fidelio, his wife Leonore in disguise, but tells Fidelio that there will be reward for the good deed in Heaven (Euch werde Lohn in bessern Welten—"You shall be rewarded in better worlds"). Fidelio further begs Rocco to be allowed to give Florestan a crust of bread, and Rocco consents. Rocco obeys his orders and sounds the alarm for Pizarro, who appears and asks if all is ready. Rocco says that it is, and instructs Fidelio to leave the dungeon, but Fidelio hides instead. Pizarro reveals his identity to Florestan, who accuses him of murder (Er sterbe! Doch er soll erst wissen—"Let him die! But first he should know"). As Pizarro brandishes a dagger, Fidelio leaps between him and Florestan and reveals her identity as Leonore, the wife of Florestan. Pizarro raises his dagger to kill her, but she pulls a gun and threatens to shoot him. Just then, the trumpet is heard, announcing the arrival of the minister. Jaquino enters, followed by soldiers, to announce that the minister is waiting at the gate. Rocco tells the soldiers to escort Governor Pizarro upstairs. Florestan and Leonore sing to their victory as Pizarro declares that he will have revenge, while Rocco expresses his fear of what is to come (Es schlägt der Rache Stunde—"Revenge's bell tolls"). Together, Florestan and Leonore sing a love duet (O namenlose Freude!—"O unnamed joy!"). Here, the overture "Leonore No. 3" is sometimes played. The prisoners and townsfolk sing to the day and hour of justice which has come (Heil sei dem Tag!—"Hail to the day!"). The minister, Don Fernando, announces that tyranny has ended. Rocco enters, with Leonore and Florestan, and he asks Don Fernando to help them (Wohlan, so helfet! Helft den Armen!—"So help! Help the poor ones!"). Rocco explains how Leonore disguised herself as Fidelio to save her husband. Previously in love with Fidelio, Marzelline is shocked. Rocco describes Pizarro's murder plot, and Pizarro is led away to prison. Florestan is released from his chains by Leonore, and the crowd sings the praises of Leonore, the loyal savior of her husband (Wer ein holdes Weib
