Robert le diable is an opera in five acts composed by Giacomo Meyerbeer between 1827 and 1831, to a libretto written by Eugène Scribe and Germain Delavigne. Superficially based on the medieval legend of Robert the Devil, it is regarded as one of the first French grand operas. This illustration depicts the set design by Pierre-Luc-Charles Cicéri of the opera's third act, known as the Ballet of the Nuns.Painting and lithography credit: Pierre-Luc-Charles Cicéri; additional lithography by Eugène Cicéri, Philippe Benoist, Adolphe Jean-Baptiste Bayot; restored by Adam Cuerden
