The jailer and Don Pizarro ascended, and soon Fernando ordered all the prisoners of the fortress brought before him. He had come to investigate the doings of the governor who had long been known as a great tyrant. When the unhappy men, who had been abused by starving and confinement in underground cells, stood before him, the Minister's heart was sorely touched, and Don Pizarro was more and more afraid. Presently, Rocco fearlessly brought Fidelio and Don Florestan in front of Fernando.
"Oh, great Minister, I beg you to give ear to the wrongs of this sad pair," he cried, and as Fernando looked at Florestan his eyes filled with tears.
"What, you? Florestan? My friend, whom I have so long believed was dead? Thou who wert the friend of the oppressed, who tried to bring to punishment this very wretch?" he said, looking at Pizarro; and his speech revealed why Pizarro had wanted to revenge himself upon the unhappy noble.
"Yes, yes, it is Don Florestan, my beloved husband," Fidelio answered, while the good Rocco pushed her ahead of him, closer to Fernando's side.
"She is no youth, but the noblest woman in the world, Don Fernando," Rocco cried, almost weeping in his agitation and relief at the turn things were taking for those with whom he sympathized.
"Just let me be heard," Pizarro called, becoming more and more frightened each moment.
"Enough of thee," Fernando answered, bitterly, in a tone that boded no good to the wretch. Then Rocco told the whole truth about the governor: how he, himself, had had to lend a hand to his wicked schemes, because as a dependent he could not control matters; and then all the prisoners cried out for Pizarro's punishment.
Fernando commanded Pizarro to give Fidelio the key of the prison, that she, the faithful wife, should have the joy of unlocking the doors and giving her husband his freedom. All the other prisoners and Fernando's suite, the jailer, his daughter, Marcelline, and Jaquino rejoiced and sang rapturously of Fernando's goodness. Pizarro was left, still uncertain of his punishment, but all hoped that he would be made to take Florestan's place in the dungeon and meet the fate he had prepared for the much abused noble.
