Parisina (also known as Parisina d'Este) is an opera (tragedia lirica), in three acts by Gaetano Donizetti. Felice Romani wrote the Italian libretto after Byron's 1816 poem Parisina.
The characters of Parisina and Duke Azzo in both Byron's poem and Donizetti's opera are very loosely based on the historical figures of Parisina Malatesta (the daughter of Andrea Malatesta) and Niccolò III d'Este.
Parisina premiered on 17 March 1833 at the Teatro della Pergola in Florence. A performance at the Teatro Argentina in Rome is the setting for a key scene in of the novel The Count of Monte Cristo by Alexandre Dumas.
In Duke Azzo's palace, Ernesto and other nobles await his arrival (È desto il duca?). Azzo appears and tells Ernesto about his fear that his wife, Parisina, has betrayed him for another man, as had his first wife, Matilde. When Azzo leaves, Ugo arrives. Ugo, who was raised by Ernesto, was once a favourite of Azzo but was later exiled. Ernesto is overcome by fear when he sees his foster son, knowing that his exile had not ended and Azzo was still angry at him. His fear worsens when Ugo reveals his love for Parisina to him.
Meanwhile, Parisina with her faithful Imelda and her other handmaids are resting in the garden. They hear knights arriving for the festivities, amongst whom is Ugo. When Parisina and Ugo are alone, she urges him to flee. They are interrupted by the arrival of the Duke. In a fury, he demands to know what Ugo is doing there. Parisina defends Ugo which only increases the Duke's anger (Il difende! E in sua difesa tanto adopra).
By the shores of the River Po. Azzo tells Ugo he may remain for the festivities, just as Ugo and his men are about to get on their boat. Parisina follows her husband and courtiers to the palace for the banquet (Vieni, vieni, e in sereno sembiante). Ernesto, Ugo, and Parisina are consumed by fear, while Azzo is consumed by his anger (Ma divoro nel cor tremante un timor/furor che non posso frenar).
