Question: In which region of France was the opera Sabinus first performed ?
Context: The Palace of Versailles, Château de Versailles, or simply Versailles ( or ; ] ), is a royal château in Versailles in the Île-de-France region of France.  It is now open as a museum, and a very popular tourist attraction. 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. This is a partial discography of William Tell (French: "Guillaume Tell"), an opera with music by Gioachino Rossini and a French libretto by Etienne de Jouy and Hippolyte Bis.  The work was first performed on 3 August 1829 by the Paris Opera at the Salle Le Peletier.  It was first performed in Italian as "Guglielmo Tell" in Germany on 28–29 January 1831 in Dresden and in Italy on 17 September 1831 in Lucca (translated by Calisto Bassi). Sabinus is an opera by the composer François-Joseph Gossec.  It originally took the form of a "tragédie lyrique" in five acts (later reduced to four).  The French-language libretto, by Michel Paul Guy de Chabanon, concerns the revolt of the Gaulish nobleman Julius Sabinus and his wife Epponina (Éponine) against Roman rule.  The opera had its first performance at Versailles on 4 December 1773 in the presence of King Louis XV, before transferring to the Paris Opéra on 22 February 1774.  "Sabinus" was not a success, even in a revised four-act version, and was soon withdrawn.  Assessments of the music has been mixed, but some modern critics share Gossec's view that "Sabinus" prefigures the revolution in operatic practice Christoph Willibald von Gluck would soon introduce to Paris. Thésée ("Theseus") is a "tragédie en musique", an early type of French opera, in a prologue and five acts with music by Jean-Baptiste Lully and a libretto by Philippe Quinault based on Ovid's "Metamorphoses".  It was first performed on 11 January 1675 by the Paris Opera for the royal court at the Château de Saint-Germain-en-Laye and was first performed in public in April at the Théâtre du Palais-Royal in Paris. Prima la musica e poi le parole ("First the music and then the words"), also called "Prima la musica, poi le parole " is an opera in one act by Antonio Salieri to a libretto by Giovanni Battista Casti.  The work was first performed on 7 February 1786 in Vienna, following a commission by the Emperor Joseph II.  The opera (more specifically, a "divertimento teatrale ") was first performed at one end of the orangery of the Schönbrunn Palace in Vienna by an Italian troupe: simultaneously, Mozart's "Der Schauspieldirektor" was staged at the other end. Amadis de Gaule, or Amadis des Gaules ("Amadis of Gaul"), is a French opera in three acts by the German composer Johann Christian Bach.  The libretto is a revision by Alphonse de Vismes of "Amadis" by Philippe Quinault, originally set by Jean-Baptiste Lully in 1684, which in turn, was based on the knight-errantry romance "Amadis de Gaula" (1508).  Bach's opera was first performed at the Académie Royale de Musique, Paris on 14 December 1779.  It followed the contemporary French fashion for resetting libretti by Quinault ("Armide" by Gluck and "Roland" by Piccinni are other examples of this trend).  The work was not a success with the Parisian public, mainly because it pleased neither the supporters of Gluck nor those of Piccinni, the two leading rival opera composers in France at the time.  It was the last opera J. C. Bach composed. La liberazione di Ruggiero dall'isola d'Alcina ("En."  "The Liberation of Ruggiero from the island of Alcina") is a comic opera in four scenes by Francesca Caccini, first performed 3 February 1625 at the Villa di Poggio Imperiale in Florence, with a libretto by Ferdinando Saracinelli, based on Ludovico Ariosto's "Orlando Furioso".  It is the first opera written by a woman, and was long considered to be the first Italian opera to be performed outside of Italy.  It was performed to celebrate a visit from Prince Władysław of Poland during Carnival 1625, and it had a revival in Warsaw in 1628.  The work was commissioned by Regent Archduchess Maria Maddalena of Austria, wife of Cosimo II de' Medici, for whom Caccini worked.  "Ruggiero" was printed under the protection of Maria Magdalena in 1625, only five years after the first printed opera in Italy.  It is the only opera by Francesca Caccini to survive. The Fly is an opera in two acts by Canadian composer Howard Shore, with a libretto by David Henry Hwang.  It was commissioned by the Théâtre du Châtelet in Paris, France, where it premiered on 2 July 2008, and by Edgar Baitzel, then director of the Los Angeles Opera, where the opera was first performed on 7 September 2008.  The work was broadcast by Radio France's station France Musique on 2 August 2008. James Andrew Olds (born 20 February 1986) is an Australian bass-baritone.
