Which opera has more parts including acts and tableaux, Le roi d'Ys or Stiffelio?
Stiffelio Stiffelio is an opera in three acts by Giuseppe Verdi, from an Italian libretto by Francesco Maria Piave. The origin of this was the novel “Le pasteur d’hommes”, by Émile Souvestre, which was published in 1838. This was adapted into the French play "Le pasteur, ou L'évangile et le foyer" by Émile Souvestre and Eugène Bourgeois. That was in turn translated into Italian by Gaetano Vestri as "Stifellius"; this formed the basis of Piave's libretto.
The Barber of Seville (play) The Barber of Seville or the Useless Precaution (French: "Le Barbier de Séville ou la Précaution inutile" ) is a French play by Pierre Beaumarchais, with original music by Antoine-Laurent Baudron. It was initially conceived as a comic opera, and was rejected as such in 1772 by the Comédie-Italienne. The play as it is now known was written in 1773, but, due to legal and political problems of the author, it was not performed until February 23, 1775, at the Comédie-Française in the Tuileries. It is the first play in a trilogy of which the other constituents are "The Marriage of Figaro" and "The Guilty Mother".
