Griselda
King Gualtiero’s marriage to the shepherdess Griselda provokes rebellion. He secretly sent their daughter Costanza to be raised by Prince Corrado and now plans to marry her, though she loves Roberto and does not know her parentage. Gualtiero dismisses Griselda, who returns to the countryside. Ottone pursues and tries to kidnap her, but Gualtiero stops him and brings Griselda back as Costanza’s slave. When Griselda refuses Ottone and proves her faithfulness, Gualtiero takes her back as his wife, reveals Costanza’s identity, and allows her to marry Roberto.
