 The libretto was written by Jacopo Ferretti, based on the fairy tale "Cendrillon" by Charles Perrault.
 The opera was first performed in Rome's Teatro Valle on 25 January 1817.
Francilla Pixis (15 May 1816 – ?
1888) was a German mezzo-soprano.
 She was born Franziska Helma Göhringer in Lichtenthal near Baden-Baden.
 She was initially trained by the pianist and composer Johann Peter Pixis who adopted her when she was 15 but also studied with Henriette Sontag and Ferdinando Paer.
 She made her concert debut in London in 1833 and her operatic debut in 1834 in Karlsruhe.
 She subsequently sang in Vienna, Paris, London, and Italy both on the opera stage and in successful concert tours with her adoptive father.
 In Italy she made her La Scala debut in 1838 in the title role of Rossini's "La Cenerentola" and also sang at the Teatro San Carlo in Naples and the Teatro Massimo in Palermo.
 In 1840 she created the title role in Giovanni Pacini's "Saffo", which he wrote expressly for her voice.
 Pixis married a Sicilian nobleman, Giovanni di Sant'Onofrio del Castillo, in 1843 and retired from the stage three years later.
 Their son, Ugo di Sant'Onofrio del Castillo, served in the Italian Parliament, first in the Chamber of Deputies from 1888 until 1913 and later in the Senate.

Cendrillon ("Cinderella") is a French opera in three acts by the Maltese-born composer Nicolas Isouard.
 It takes the form of an "opéra comique" with spoken dialogue between the musical numbers, although its authors designated it an "opéra féerie".
 The libretto, by Charles Guillaume Etienne, is based on Charles Perrault's fairy tale "Cinderella".
 The work was first performed by the Opéra-Comique at the Salle Feydeau in Paris on 22 February 1810.
 "Cendrillon" was a success throughout Europe until its popularity was eclipsed by that of Rossini's opera on the Cinderella theme, "La Cenerentola" (1817).
Ivanhoé is an 1826 pastiche opera in three acts with music by Gioachino Rossini to a French-language libretto by Émile Deschamps and Gabriel-Gustave de Wailly, after Walter Scott's novel of the same name.
 The music was adapted, with the composer's permission, by the music-publisher Antonio Pacini from Rossini's operas, namely "Semiramide", "La Cenerentola", "La gazza ladra", and "Tancredi" in order to introduce his music to Paris.
 An examination of the score shows that Pacini also used music from "Bianca e Faliero", "Armida", "Maometto II", "Aureliano in Palmira", "Sigismondo", "Torvaldo e Dorliska", "Mosè in Egitto" and an amount of newly composed music including fanfares and the gallop that was later to become famous from its inclusion in "Guglielmo Tell".
 The work was premiered on 15 September 1826, at the Odéon Theatre.
Agostino Rovere (1804, Monza - 1865, New York City) was an Italian operatic bass.

 He returned to that opera house the following year to create the role of La Rocca in the world premiere of Giuseppe Verdi's "Un giorno di regno".
 In 1842 he portrayed the role of Marquis de Boisfleury in the world premiere of Donizetti's "Linda di Chamounix" at the Kärntnertortheater in Vienna.
 In 1847-1848 he was committed to the Royal Opera House in London where he sang Bartolo in Wolfgang Amadeus Mozart's "The Marriage of Figaro", Don Magnifico in Rossini's "La Cenerentola", Dulcamara in Donizetti's "L'elisir d'amore", Leporello in "Don Giovanni", and Mustafà in Gioachino Rossini's "L'italiana in Algeri"
