Étienne-Joseph Floquet (23 November 174810 May 1785) was a French composer, mainly of operas.
 He was born in Aix-en-Provence and began his career by writing church music, before moving to Paris in 1767.
 There, Floquet made a name for himself with the requiem he wrote for the funeral of the composer Jean-Joseph de Mondonville in 1772.
 Floquet's first work for the Paris Opéra, the "ballet héroïque" "L'union de l'amour et les arts," was a triumph, enjoying 60 performances between its premiere in September 1773 and January 1774.
 The audience at the premiere was so enthusiastic that the performance had to be stopped several times because of the applause and, at the final curtain, Floquet was presented on stage, the first composer in the history of the Paris Opéra to enjoy such an honour.
 However, the arrival of the German composer Christoph Willibald Gluck in Paris later that year changed French musical taste and Floquet's style became unfashionable.
 After the failure of his next opera, "Azolan", Floquet decided to travel to Italy to perfect his musical education.
 There he studied composition under Nicola Sala in Naples and counterpoint under Padre Martini in Bologna, where he turned momentarily back to church music composing a "Te deum".

 It was performed in the film by Catherine Deneuve, whose voice was dubbed by Danielle Licari.

"Ippolito ed Aricia" was commissioned in 1759 by Guillaume du Tillot, a minister for Philip, Duke of Parma, on behalf of the duke and his wife, Princess Louise Élisabeth of France.
 At that time, both France and Spain thought of Parma as a strategic point of interest and subsidized the court heavily.
 The duke and his wife were particularly fond of French opera and Tillot promoted all forms of French musical theater at the court.
 However, Tillot decided that he wanted to commission an opera for the court that would merge Italian musical idioms, such as beautiful melodies and virtuosic coloratura display, with French dramatic forms like choruses, ballet, and supernatural elements.
 He approached Carlo Innocenzo Frugoni, court poet of Parma, with the idea of creating such an opera using the Italian text of Rameau's "Hippolyte et Aricie".
 He agreed, and Tillot proceeded to recruit Tommaso Traetta to compose the music and Count Francesco Algarotti to assist Frugoni with the libretto.
