Do both Simon Boccanegra and Le roi d'Ys have the same number of acts?
Le roi d'Ys Le roi d'Ys ("The King of Ys") is an opera in three acts and five tableaux by the French composer Édouard Lalo, to a libretto by Édouard Blau, based on the old Breton legend of the drowned city of Ys. That city was, according to the legend, the capital of the kingdom of Cornouaille.
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.
