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.
Toulon Opera The Toulon Opera (L'opéra de Toulon), inaugurated on 1 October 1862, is the second-largest opera house in France, after the Palais Garnier in Paris, although it opened thirteen years before the Garnier. The inaugural performance was "Les Mouquetaires de la reine", a comic opera by Fromental Halévy, followed a few days later by "La Juive", the same composer's most famous opera.
