Question: Who did the composer of  Les fêtes d'Hébé replaced as the dominant composer of French opera?

full_context: Document 1: Philippe Courbois: Philippe Courbois (fl. 1705-1730) was a French Baroque composer. It is commonly stated that he was maître de musique of the Duchess of Maine, but Michele Cabrini convincingly refutes this claim in his edition of Courbois's cantatas. At least three of his masses were performed for the King of France at Versailles. Sometime before 1710, Courbois published a book of seven cantatas with texts by Louis Fuzelier, who would later write the libretto of "Les Indes Galantes." It is these cantatas for which he is most famous today
Document 2: Jean-Philippe Rameau: Jean-Philippe Rameau (] ; (1683--)25 1683 – (1764--)12 1764 ) was one of the most important French composers and music theorists of the Baroque era. He replaced Jean-Baptiste Lully as the dominant composer of French opera and is also considered the leading French composer for the harpsichord of his time, alongside François Couperin.
Document 3: La naissance d'Osiris: La naissance d'Osiris, ou La fête Pamilie ("The Birth of Osiris, or The Festival of Pamylia") is a one-act opera by Jean-Philippe Rameau, first performed on 12 October 1754 at Fontainebleau to celebrate the birth of the future King Louis XVI. The libretto is by Rameau's frequent collaborator Louis de Cahusac. Cahusac styled the work a "ballet allégorique" ("allegorical ballet"), but it is usually categorised as an "acte de ballet". Its slender plot tells of Jupiter's announcement to a group of Egyptian shepherds of the birth of the god Osiris, who symbolises the baby prince. The piece may have started life as part of a larger work, "Les beaux jours de l'Amour", an "opéra-ballet" Rameau and Cahusac planned but never completed for reasons which are still uncertain.
Document 4: Les fêtes d'Hébé: Les fêtes d'Hébé, ou Les talens lyriques ("The Festivities of Hebe, or The Lyric Talents") is an "opéra-ballet" in a prologue and three "entrées" (acts) by the French composer Jean-Philippe Rameau. The libretto was written by Antoine Gautier de Montdorge (1707–1768). The work was first performed on 21 May 1739 by the Académie royale de musique at its theatre in the Palais-Royal in Paris..
Document 5: Lost operas by Jean-Philippe Rameau: The musical scores to several operas by the French composer Jean-Philippe Rameau have been lost. They include two major "tragédies en musique", "Samson" and "Linus", and a one-act pastoral opera "Lisis et Délie". The music to these pieces was substantially complete and was performed in rehearsal but for various reasons - including censorship in the case of "Samson" - they were never publicly staged. Rameau also wrote a "divertissement" for Alexis Piron's play "Les courses de Tempé", which did appear at the theatre in 1734. The music to all these works has been almost completely lost, although there is evidence Rameau reused some of it in his later operas. Rameau also began other operatic projects, which were either abandoned at an early stage ("Pandore") or broken up to form shorter works ("Les beaux jours de l'Amour").
Document 6: Les fêtes de l'Hymen et de l'Amour: Les fêtes de l’Hymen et de l’Amour, ou Les dieux d'Egypte is an "opéra-ballet" in three "entrées" and a prologue by the French composer Jean-Philippe Rameau. The work was first performed on March 15, 1747, at the La Grande Ecurie, Versailles, and is set to a libretto by Louis de Cahusac. The opera was originally composed as part of the celebrations for the Dauphin’s marriage to Maria Josepha of Saxony. "Les fêtes de l’Hymen" proved to be a popular work and by the March 1776 it had been performed exactly 106 times. The librettist, Cahusac, was especially pleased with the ways in which he had succeeded in giving especial import to the supernatural elements of the work—the plot is based on Egyptian mythology—and to allow particular use of impressive large-scale stage machinery, which was much admired by the audience. The opera contains seven ballets, a consequence of Cahusac’s desire to further integrate dance and drama, which grew from the typical French devotion to ballet, particularly when allied with opera.
Document 7: Jean-Baptiste Lully: Jean-Baptiste Lully (] ; born Giovanni Battista Lulli ] ; 28 November 1632 – 22 March 1687) was an Italian-born French composer, instrumentalist, and dancer who spent most of his life working in the court of Louis XIV of France. He is considered a master of the French baroque style. Lully disavowed any Italian influence in French music of the period. He became a French subject in 1661.
Document 8: Lisis et Délie: Lisis et Délie (or Lysis et Délie) was a one-act pastoral opera with music by Jean-Philippe Rameau and a libretto by Jean-François Marmontel. The musical score is now lost. It was scheduled to appear at Fontainebleau on 6 November 1753 as part of the celebrations for the birth of the royal prince Xavier, Duke of Aquitaine. It was due to form a double bill with the "comédie-ballet" "Les hommes" (words by Germain-François Poullain de Saint-Foix, music by François-Joseph Giraud). However, it was withdrawn from performance and "La danse", the third "entrée" of Rameau's "Les fêtes d'Hébé", was performed in its place. The reason given for the work's cancellation was that it was too similar to Rameau's "Daphnis et Eglé", premiered at Fontainebleau on 30 October. The libretto was published but the music does not survive. Rameau may have reused some of it in his later operas.
Document 9: Les Talens Lyriques: The French musical ensemble Les Talens Lyriques was created in Paris, France, in 1991 by the harpsichordist and orchestral conductor Christophe Rousset. This instrumental and vocal formation derives its name from the subtitle of "Les fêtes d'Hébé (1739)" an opera by Jean-Philippe Rameau.
Document 10: Nélée et Myrthis: Nélée et Myrthis (or Mirthis) is a one-act opera by Jean-Philippe Rameau in the form of an "acte de ballet". Little is known about its background: the score may be incomplete and it was never staged in Rameau's lifetime. The first known performance took place at the Victoria State Opera, Melbourne, Australia on 22 November 1974. "Nélée et Myrthis" may have been intended to form part of a larger "opéra-ballet" to be called "Les beaux jours de l'Amour". The name of the librettist is unknown but it was probably Rameau's frequent collaborator Louis de Cahusac.
Document 11: Baroque music: Baroque music ( or ) is a style of Western art music composed from approximately 1600 to 1750. This era followed the Renaissance music era, and was followed in turn by the Classical era. Baroque music forms a major portion of the "classical music" canon, being nowadays widely studied, performed, and listened to. Key composers of the Baroque era include Johann Sebastian Bach, Antonio Vivaldi, George Frideric Handel, Claudio Monteverdi, Domenico Scarlatti, Alessandro Scarlatti, Henry Purcell, Georg Philipp Telemann, Jean-Baptiste Lully, Jean-Philippe Rameau, Marc-Antoine Charpentier, Arcangelo Corelli, Tomaso Albinoni, François Couperin, Giuseppe Tartini, Heinrich Schütz, Giovanni Battista Pergolesi, Dieterich Buxtehude, and Johann Pachelbel.
Document 12: Samson (opera): Samson was an opera by the French composer Jean-Philippe Rameau with a libretto by Voltaire. The work was never staged due to censorship, although Voltaire later printed his text. Rameau intended the opera on the theme of Samson and Delilah as the successor to his debut "Hippolyte et Aricie", which premiered in October 1733. Like "Hippolyte", "Samson" was a "tragédie en musique" in five acts and a prologue. Voltaire had become a great admirer of Rameau's music after seeing "Hippolyte" and suggested a collaboration with the composer in November 1733. The opera was complete by late summer 1734 and went into rehearsal. However, a work on a religious subject with a libretto by such a notorious critic of the Church was bound to run into controversy and "Samson" was banned. An attempt to revive the project in a new version in 1736 also failed. The score is lost, although Rameau recycled some of the music from "Samson" in his later operas.
Document 13: Le feste d'Apollo: Styled a "festa teatrale", "Le feste d'Apollo" consists of a prologue and three self-contained acts on the model of French "opéra-ballet" (the court of Parma was passionately interested in French culture). Gluck knew the Archduchess Maria Amalia well as she had sung in two of his operas, "Il Parnaso confuso" and "La corona", in Vienna. The composer recycled a lot of music from his earlier operas in the score of "Le feste". In fact, the whole of the third act, "Orfeo", is a shorter reworking of his most famous piece, "Orfeo ed Euridice" (1762). The overture to the prologue is taken from "Telemaco". Gluck later reused some of the choruses in two of the operas he wrote for Paris, "Iphigénie en Aulide" and "Iphigénie en Tauride".
Document 14: Les fêtes de Paphos: Les fêtes de Paphos ("The Festivals of Paphos") is an "opéra-ballet" in three acts (or "entrées") by the French composer Jean-Joseph Cassanéa de Mondonville. The work was described as a "ballet héroïque" on the title page of the printed score. Each act had a different librettist. "Les fêtes de Paphos" was first performed at the Académie royale de musique, Paris on 9 May 1758 and was a popular success. Mondonville recycled material from two of his previous operas for the first two acts, namely "Erigone" (1747) and "Vénus et Adonis" (1752), both originally composed for Madame de Pompadour's Théâtre des Petits Cabinets.
Document 15: Antoine Gautier de Montdorge: Antoine-César Gautier de Montdorge (or Mondorge) (17 January 1701 or 1707 - 24 October 1768) was a French man of letters, best known for writing the libretto for Rameau's "opéra-ballet" "Les fêtes d'Hébé" (1739). Born in Lyon, he moved to Paris, where he worked as a financier (with the title "maître à la Chambre aux deniers du Roi"). He was a friend and neighbour of Rameau's patron Alexandre Le Riche de La Pouplinière and probably met the composer at La Pouplinière's salon. Montdorge was not identified as the author of "Les fêtes d'Hébé" on any of its printed editions. It was first attributed to him by Antoine de Léris in the 1763 edition of his "Dictionnaire portatif des théâtres". Reviewers severely criticised the literary weakness of the work. The only other opera libretto Montdorge wrote was the one-act comédie-ballet "L'opéra de société" for Jean-François Giraud in 1762. He described his experience working as a librettist for Rameau in the anonymously published "Réflections d'un peintre sur l'opéra" (1743).
