At home in Palermo, Camiola is oppressed by the arrogant attentions of Fulgentio. She refuses him, and when he slanders her in revenge, she protests to the King, leading to the favourite's disgrace. Bertoldo languishes in chains in a dungeon—but he is redeemed when Camiola pays his ransom. Roberto has decreed that no "man" among his subjects pay for Bertoldo's freedom; but Camiola is not a man. Bertoldo's difficulties have worked a change on Camiola's resolution. Her ransom comes with a price: Bertoldo signs a marriage contract to attain his freedom.
