Act I Courtiers and the Duke of Mantua's hunchback jester Rigoletto amuse themselves. The duke seduces and then abandons women to pass the time. He mocks their husbands. He has not yet concluded his latest adventure with a young woman. Every Sunday, for three months, he has watched her in church. With the help of Rigoletto's stinging tongue the duke humiliates Countess Ceprano in front of her husband. When Rigoletto suggests that cuckolded Count Ceprano be executed, the mood suddenly turns against him. The courtiers demand revenge for Rigoletto's maliciousness. Marullo reveals that the hunchback keeps a secret lover hidden away at home. Count Monterone interrups the party. He intends to be avenged for his daughter, who the duke and his men dishonoured. When Rigoletto mocks the despairing father, Monterone curses the duke and his jester. Rigoletto cannot get Monterone's curse out of his mind. Out on the street Sparafucile, a professional assassin, and his sister Maddalena offer their services. Rigoletto sees his mirror image in the murderer: Sparafucile kills with a dagger, he with his humiliating words. Rigoletto bemoans his fate and tries to justify his actions to himself. He comes home, where his daughter Gilda is locked away from the outside world, looked after by her governess Giovanna. Gilda means everything to her father. She grew up in a convent and only came to live with him three months ago. Gilda longs for life and freedom. Rigoletto avoids answering her questions about her dead mother and his name. Before going out again he orders Giovanna to guard his daugher well. The duke, disguised as a poor student, Gualtier Maldé, forces his way into the room. He proclaims his love for her, which Gilda immediately returns. She is overjoyed. Giovanna hears footsteps, the duke is sent away. Gilda falls into a reverie about her beloved's name. Courtiers break into the house to steal Rigoletto's supposed lover. Rigoletto, his eyes bound, takes part in the crime in the mistaken belief that they are abducting Countess Ceprano. Too late, he realises that he has helped steal his own daughter. (interval) Act II The duke is desolate that his beloved seems to have been stolen from him.
