The Podestà, Cavalier Ramiro and Serpetta descend the staircase as Sandrina and Nardo work in the garden. Together they praise the lovely day, but their happiness is feigned ("Che lieto giorno"). Sandrina is wretched because Don Anchise, the Podestà, is in love with her. Nardo is frustrated by Serpetta, who teases him but refuses to respond to his affections. Ramiro is bitter after being tossed aside by Arminda, and, because she has set her own cap at the Podestà, Serpetta is angry at Sandrina. The Podestà attempts to console Ramiro, but Ramiro can think of none but Arminda ("Se l'augellin sen fugge"). When they are left alone, Don Anchise professes love to Sandrina ("Dentro il mio petto"). Sandrina refuses his advances as politely as possible and, when Serpetta rudely interrupts, makes her escape.
