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".
La Foire de Guibray La Foire de Guibray (English: The Guibray Fair ) is a one-act farce by Alain-René Lesage. It was first performed at the Foire de Saint Laurent in 1714. "La Foire de Guibray" is actually a prologue to two other one-act farces, "Arlequin Mahomet" and "Le Tombeau de Nostradamus". Between the three works, Lesage created a comedy in three acts.
