Griselda
King Gualtiero married the poor shepherdess Griselda, but the marriage was unpopular. When their daughter Costanza was born, he secretly sent her to be raised by Prince Corrado. Facing rebellion, Gualtiero renounces Griselda and plans to marry Costanza, who loves Corrado’s brother Roberto. Griselda returns to the countryside, where courtier Ottone pursues her. Gualtiero rescues her from Ottone’s kidnapping attempt and brings her back as Costanza’s slave. Griselda remains faithful, and Gualtiero restores her as his wife, reveals Costanza’s parentage, and allows her to marry Roberto.
