Ivanhoé contains music from the opera that has a libretto by whom?
Ivanhoé 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.

The music deploys English folk tunes, including "Greensleeves". Originally titled "The Fat Knight", the opera premiered at the Parry Opera Theatre, Royal College of Music, London on 21 March 1929. Its first professional performance was on 9 April 1946 at Sadler's Wells Theatre.
