La favorite
La favorite (The Favourite, frequently referred to by its Italian title: La favorita) is a grand opera in four acts by Gaetano Donizetti to a French-language libretto by Alphonse Royer and Gustave Vaëz, based on the play Le comte de Comminges by Baculard d'Arnaud with additions by Eugène Scribe based on the story of Leonora de Guzman. The opera concerns the romantic struggles of the King of Castile, Alfonso XI, and his mistress, the "favourite" Leonora, against the backdrop of the political wiles of receding Moorish Spain and the life of the Catholic Church.
