Question: Iphigénie en Tauride was an operat by which classical composer?

full_context: Document 1: Iphigénie en Tauride (Desmarets and Campra): Iphigénie en Tauride (English: "Iphigeneia in Tauris") is an opera by the French composers Henri Desmarets and André Campra. It takes the form of a "tragédie en musique" in a prologue and five acts. The libretto is by Joseph-François Duché de Vancy with additions by Antoine Danchet. Desmarets had begun work on the opera around 1696 but abandoned it when he was forced to go into exile in 1699. Campra and his regular librettist Danchet took up the piece and wrote the prologue, most of Act Five, two arias in Act One, an aria for Acts Two and Three, and two arias for the fourth act. The plot is ultimately based on Euripides' tragedy "Iphigeneia in Tauris".

The list includes all of the studio recordings and also some live performances available on audio CD and DVD.
Document 3: Iphigénie en Tauride (Piccinni): Iphigénie en Tauride ("Iphigeneia in Tauris") is a tragédie lyrique in four acts by Niccolò Piccinni, which was first performed on 23 January 1781 by the Académie royale de musique (the Paris Opéra) in the second Salle du Palais-Royal. The opera's libretto, by Alphonse du Congé Dubreuil, is based on a play of the same name by Claude Guimond de La Touche, although the ultimate source was the tragedy "Iphigeneia in Tauris" by Euripides.
Document 4: 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 5: Orfeo ed Euridice: Orfeo ed Euridice (French version: Orphée et Eurydice ; English: "Orpheus and Eurydice") is an opera composed by Christoph Willibald Gluck based on the myth of Orpheus, set to a libretto by Ranieri de' Calzabigi. It belongs to the genre of the "azione teatrale", meaning an opera on a mythological subject with choruses and dancing. The piece was first performed at the Burgtheater in Vienna on 5 October 1762 in the presence of Empress Maria Theresa. "Orfeo ed Euridice" is the first of Gluck's "reform" operas, in which he attempted to replace the abstruse plots and overly complex music of "opera seria" with a "noble simplicity" in both the music and the drama.
Document 6: Il trovatore discography: This is a partial discography of Giuseppe Verdi's opera "Il trovatore" ("The Troubadour") and "Le trouvère" (the revised version in French translation). At least 83 recordings exist of the opera as a whole, made between 1912 and 2011, although not all of them are absolutely complete. Of these, 45 are live audio recordings, 22 are studio audio recordings, and 16 are videos or movies. "Il trovatore" was first performed at the Teatro Apollo, Rome on 19 January 1853. "Le trouvère" was first presented on 12 January 1857.
Document 7: Paride ed Elena: Paride ed Elena (] ; "Paris and Helen") is an opera by Christoph Willibald Gluck. It is the third of Gluck's so-called reform operas for Vienna, following "Alceste" and "Orfeo ed Euridice", and the least often performed of the three. Like its predecessors, the libretto was written by Ranieri de' Calzabigi. The opera tells the story of the events between the Judgment of Paris and the flight of Paris and Helen to Troy. It was premiered at the Burgtheater in Vienna on 3 November 1770.
Document 8: Orfeo ed Euridice discography: The following discography for Gluck's opera "Orfeo ed Euridice" is mainly based on the research of Giuseppe Rossi, which appeared in the programme notes to the performance of the work at the 70th Maggio Musicale Fiorentino in 2007, under the title "Discografia – Christoph Willibald Gluck – Orfeo ed Euridice (Orphée et Eurydice)". Rossi's data has been checked against the sources referenced in the notes.
Document 9: Il re pastore (Gluck): Il re pastore ("The Shepherd King") is an opera by the composer Christoph Willibald Gluck. It takes the form of a "dramma per musica" in three acts. The Italian-language libretto is by Pietro Metastasio. The opera premiered on 8 December 1756 at the Burgtheater, Vienna.
Document 10: Iphigénie en Tauride: Iphigénie en Tauride ("Iphigenia in Tauris") is a 1779 opera by Christoph Willibald Gluck in four acts. It was his fifth opera for the French stage. The libretto was written by Nicolas-François Guillard.
Document 11: Iphigénie en Tauride discography: This is a discography of Iphigénie en Tauride, an opera by Christoph Willibald Gluck, first performed at the Paris Opéra on May 18, 1779.
Document 12: Armide (Gluck): Gluck set the same libretto Philippe Quinault had written for Lully in 1686, based on Torquato Tasso's "Gerusalemme liberata" ("Jerusalem Delivered"). Gluck seemed at ease in facing French traditions head-on when he composed "Armide". Lully and Quinault were the very founders of serious opera in France and "Armide" was generally recognized as their masterpiece, so it was a bold move on Gluck's part to write new music to Quinault's words. A similar attempt to write a new opera to the libretto of "Thésée" by Jean Joseph de Mondonville in 1765 had ended in disaster, with audiences demanding it be replaced by Lully's original. By utilizing "Armide", Gluck challenged the long-standing and apparently inviolable ideals of French practice, and in the process he revealed these values capable of renewal through "modern" compositional sensitivities. Critical response and resultant polemic resulted in one of those grand imbroglios common to French intellectual life. Gluck struck a nerve in French sensitivities, and whereas "Armide" was not one of his more popular works, it remained a critical touchstone in the French operatic tradition and was warmly praised by Berlioz in his "Memoirs". Gluck also set a minor fashion for resetting Lully/Quinault operas: Gluck's rival Piccinni followed his example with "Roland" in 1778 and "Atys" in 1780; in the same year, Philidor produced a new "Persée"; and Gossec offered his version of "Thésée" in 1782. Gluck himself is said to have been working on an opera based on "Roland", but he abandoned it when he heard Piccinni had taken on the same libretto.
Document 13: Giulio Sabino: The opera, staged in six or seven European countries at the end of the 18th century, was the subject of a parody in Antonio Salieri's 1786 work "Prima la musica e poi le parole".
Document 14: Iphigénie en Aulide: Iphigénie en Aulide ("Iphigeneia in Aulis") is an opera in three acts by Christoph Willibald Gluck, the first work he wrote for the Paris stage. The libretto was written by François-Louis Gand Le Bland Du Roullet and was based on Jean Racine's tragedy "Iphigénie". It was premiered on 19 April 1774 by the Paris Opéra in the second Salle du Palais-Royal and revived in a slightly revised version the following year.
Document 15: Christoph Willibald Gluck: Christoph Willibald (Ritter von) Gluck (] ; 2 July 1714 – 15 November 1787) was a composer of Italian and French opera in the early classical period. Born in the Upper Palatinate (now part of Germany) and raised in Bohemia, he gained prominence at the Habsburg court at Vienna, where he brought about the practical reform of opera's dramaturgical practices that many intellectuals had been campaigning for over the years. With a series of radical new works in the 1760s, among them "Orfeo ed Euridice" and "Alceste", he broke the stranglehold that Metastasian "opera seria" had enjoyed for much of the century.
