Abandoned in the wilderness, Sandrina is nearly frightened out of her wits ("Crudeli, fermate!"). Small search parties composed of the Count and Nardo, Arminda, Serpetta, and the Podestà soon arrive (Finale: "Fra quest'ombra"). In the darkness the Podestà mistakes Arminda for Sandrina and she him for the Count, while the Count thinks Serpetta is Sandrina and she takes him for the Podestà. Nardo manages to find Sandrina by following her voice, and Ramiro then appears with footmen and torches. As the embarrassed and mismatched pairs separate, Belfiore and Sandrina find each other and lose their senses. They see themselves as the Greek gods Medusa and Alcides, and the astonished onlookers as forest nymphs. Oblivious of their surroundings, the two begin to dance.
