 All grieve over Ernesto's death at the hands of "a traitor, a vile pirate".Gualtiero, to the amazement of Ernesto's retainers, gives himself up to the knights and, as he is taken away, he prays that Imogene may forgive him ("Tu vedrai la sventurata" / "You will see the unhappy lady / whom I caused so many tears / and tell her if I wronged her / I also knew how to avenge her").She appears in a state of anguish and sees visions of her dead husband and her son ("Col sorriso d'innocenza ... Oh sole, ti vela di tenebre oscure" / "With the smile of innocence / with the glance of love / pray speak to your father of clemency and pardon").
