Do both Simon Boccanegra and Le roi d'Ys have the same number of acts?
Simon Boccanegra Simon Boccanegra (] ) is an opera with a prologue and three acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the play "Simón Bocanegra" (1843) by Antonio García Gutiérrez, whose play "El trovador" had been the basis for Verdi's 1853 opera, "Il trovatore".
L'Aiglon L'Aiglon is a play in six acts by Edmond Rostand based on the life of Napoleon II, who was the son of Emperor Napoleon I and his second wife, Empress Marie Louise. The title of the play comes from a nickname for Napoleon II, the French word for "eaglet" (a young eagle).
