Prosper-Didier Deshayes (mid 18th century – 1815) was an opera composer and dancer who lived and worked in France.
 In 1764 he was a balletmaster at the Comédie-Française.
 By 1774 he had become an assistant ("adjoint") at the Paris Opéra.
 His first opera "Le Faux serment ou La Matrone de Gonesse", a "comédie mêlée d'ariettes" in two acts, was first performed on 31 December 1785 at the Théâtre des Beaujolais in Paris and became a popular success.
 He went on to have another 18 works performed at various venues in Paris, but only two, "La faut serment" and "Zélie, ou Le mari à deux femmes", a 3-act "drame" first performed at the Salle Louvois on 29 October 1791, were ever published as musical scores.
 He also participated in the collaborative Revolutionary opera "Le congrès des rois", a 3-act "comédie mêlée d'ariettes", which combined music written by Deshayes and 11 other composers and was first performed by the Opéra-Comique at the Salle Favart on 26 February 1794.
 He died in Paris.
Falstaff (] ) is an opera in three acts by the Italian composer Giuseppe Verdi (18131901).

 The work premiered on 9 February 1893 at La Scala, Milan.
La vestale ("The Vestal Virgin") is an opera composed by Gaspare Spontini to a French libretto by Étienne de Jouy.
 It takes the form of a "tragédie lyrique" in three acts.
 It was first performed on 15 December 1807 by the Académie Impériale de Musique (Paris Opera) at the Salle Montansier, and is regarded as Spontini's masterpiece.
 The musical style shows the influence of Gluck and looks forwards to the works of Berlioz, Wagner and French Grand Opera.

 Over the next several years he played mostly leading roles at the Teatro Costanzi in Rome including Rodolfo in Puccini's "La Bohème", Fenton in Verdi's "Falstaff", and the Ernesto in Donizetti's "Don Pasquale".
 In the early 1920s he joined the roster at La Scala where he began playing more buffo roles than leading roles.
 In 1921, he sang the role of doctor Cajus in Verdi's Falstaff at La Scala and in 1922 was Filipeto in the company's first production of Ermanno Wolf-Ferrari's "I quattro rusteghi".
