Egoldo and some peasants arrive with some of their produce, which they hope Corradino will accept ("Zitti; nessun qui v'è" - "Quiet, no-one is here"). Aliprando draws their attention to two inscriptions on the castle gates ("Chi vi guida a queste mura?" - "Who brings you to these walls?"), but since the peasants have not been taught to read, he is obliged to read them out: "Anyone entering without permission will have their heads split in two" and "Anyone who disturbs the peace will be starved to death". He and Ginardo confirm that the ferocious Corradino will have no hesitation in carrying out these threats, and furthermore he has a particular hatred of women ("Se viene il Cerbero fioccano i guai" - "When Cerberus comes, woes rain down"). The alarmed peasants disperse rapidly. Ginardo asks Udolfo to check that Corradino's prisoners are not being ill-treated, except that he himself will visit the most recent arrival, Edoardo, the son of Corradino's enemy Raimondo Lopez.
