Question: Who is often called the inventor of opera, Hector Berlioz or Jacopo Peri ?

full_context: Document 1: Symphonie fantastique: Symphonie fantastique: Épisode de la vie d'un artiste ... en cinq parties ("Fantastical Symphony: An Episode in the Life of an Artist, in Five Parts") Op. 14, is a program symphony written by the French composer Hector Berlioz in 1830. It is an important piece of the early Romantic period. The first performance was at the Paris Conservatoire in December 1830. Franz Liszt made a piano transcription of the symphony in 1833 (S. 470).
Document 2: Jacopo Corsi: Jacopo Corsi (17 July 1561 – 29 December 1602) was an Italian composer of the late Renaissance and early Baroque and one of Florence's leading patrons of the arts, after only the Medicis. His best-known work is "Dafne" (1597/98), whose score he wrote in collaboration with Jacopo Peri. Six fragments of the score have survived, two by Corsi and four by Peri. The libretto, by Ottavio Rinuccini, has survived intact. Despite priority quibbles at the time, Dafne is generally accepted as the first opera.
Document 3: Te Deum (Berlioz): The Te Deum (Op. 22 / H.118) by Hector Berlioz (1803–1869) was completed in 1849. Like the earlier and more famous ""Grande Messe des Morts"", it is one of the works referred to by Berlioz in his Memoirs as "the enormous compositions which some critics have called architectural or monumental music." While the orchestral forces required for the "Te Deum" are not as titanic as those of the "Requiem", the work calls for an organ that can compete on equal terms with the rest of the orchestra. It lasts approximately fifty minutes and derives its text from the traditional Latin Te Deum, although Berlioz changed the word order for dramatic purposes.
Document 4: Euridice (Peri): Euridice (also Erudice or Eurydice) is an opera by Jacopo Peri, with additional music by Giulio Caccini. It is the earliest surviving opera, Peri's earlier "Dafne" being lost. (Caccini wrote his own "Euridice" even as he supplied music to Peri's opera, published this version before Peri's was performed, in 1600, and got it staged two years later.) The libretto by Ottavio Rinuccini is based on books X and XI of Ovid's "Metamorphoses"
Document 5: Hector Berlioz: Louis-Hector Berlioz (] (English: ); 11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions "Symphonie fantastique" and "Grande messe des morts" (Requiem). Berlioz made significant contributions to the modern orchestra with his "Treatise on Instrumentation". He specified huge orchestral forces for some of his works, and conducted several concerts with more than 1,000 musicians. He also composed around 50 songs. His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, and Gustav Mahler.
Document 6: Dafne: Dafne is the earliest known work that, by modern standards, could be considered an opera. The libretto by Ottavio Rinuccini survives complete; the mostly-lost music was completed by Jacopo Peri, but at least two of the six surviving fragments are by Jacopo Corsi. "Dafne" was first performed during Carnival of 1598 (1597 old style) at the Palazzo Corsi.
Document 7: Richard Wagner: Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Document 8: List of major opera composers: This list provides a guide to opera composers, as determined by their presence on a majority of compiled lists of significant opera composers. (See the "Lists Consulted" section for full details.) The composers run from Jacopo Peri, who wrote the first ever opera in late 16th century Italy, to John Adams, one of the leading figures in the contemporary operatic world. The brief accompanying notes offer an explanation as to why each composer has been considered major. Also included is a section about major women opera composers, compiled from the same lists. For an introduction to operatic history, see opera. The organisation of the list is by birthdate.
Document 9: L'Orfeo: L'Orfeo (SV 318) (] ), sometimes called La favola d'Orfeo ] , is a late Renaissance/early Baroque "favola in musica", or opera, by Claudio Monteverdi, with a libretto by Alessandro Striggio. It is based on the Greek legend of Orpheus, and tells the story of his descent to Hades and his fruitless attempt to bring his dead bride Eurydice back to the living world. It was written in 1607 for a court performance during the annual Carnival at Mantua. While Jacopo Peri's "Dafne" is generally recognised as the first work in the opera genre, and the earliest surviving opera is Peri's "Euridice", "L'Orfeo" is the earliest that is still regularly performed.
Document 10: Prix de Rome cantatas (Berlioz): The French composer Hector Berlioz made four attempts at winning the Prix de Rome music prize, finally succeeding in 1830. As part of the competition, he had to write a cantata to a text set by the examiners. Berlioz's efforts to win the prize are described at length in his "Memoirs". He regarded it as the first stage in his struggle against the musical conservatism represented by the judges, who included established composers such as Luigi Cherubini, François-Adrien Boieldieu and Henri Montan Berton. Berlioz's stay in Italy as a result of winning the prize also had a great influence on later works such as "Benvenuto Cellini" and "Harold en Italie". The composer subsequently destroyed the scores of two cantatas ("Orphée" and "Sardanapale") almost completely and reused music from all four of them in later works. There was a revival of interest in the cantatas in the late 20th century, particularly "La mort de Cléopâtre", which has become a favourite showcase for the soprano and mezzo-soprano voice.
Document 11: Jacopo Peri: Jacopo Peri (Zazzerino) (20 August 156112 August 1633) was an Italian composer and singer of the transitional period between the Renaissance and Baroque styles, and is often called the inventor of opera. He wrote the first work to be called an opera today, "Dafne" (around 1597), and also the first opera to have survived to the present day, "Euridice" (1600).
Document 12: Requiem (Berlioz): The Grande Messe des morts (or Requiem), Op. 5, by Hector Berlioz was composed in 1837. The "Grande Messe des Morts" is one of Berlioz's best-known works, with a tremendous orchestration of woodwind and brass instruments, including four antiphonal offstage brass ensembles placed at the corners of the concert stage. The work derives its text from the traditional Latin Requiem Mass. It has a duration of approximately ninety minutes, although there are faster recordings of under seventy-five minutes.
Document 13: La Symphonie fantastique: La Symphonie fantastique is a 1942 French drama film by Christian-Jaque and produced by the German-controlled French film production company Continental Films. The film is based upon the life of the French composer Hector Berlioz. The title is taken from the five-movement programmatic "Symphonie fantastique" of 1830. The film lasts around 90 minutes and was first shown at the 'Normandie' cinema in Paris on 1 April 1942. The posters at the premiere contained the sub-title 'La Vie passionnée et glorieuse d'un génie' (which links with the quote from Hugo at the very end of the film).
Document 14: Dafne (Opitz-Schütz): Die Dafne (1627) to a libretto by Martin Opitz (which survives), and music by Heinrich Schütz (which is lost), has traditionally been regarded as the first German opera, though it has also been proposed more recently that it was in fact a spoken drama with inserted song and ballet numbers.
Document 15: Euridice (Caccini): Euridice is an opera in a prologue and one act by the Italian composer Giulio Caccini. The libretto, by Ottavio Rinuccini, had already been set by Caccini's rival Jacopo Peri in 1600. Caccini's version of "Euridice" was first performed at the Pitti Palace, Florence on 5 December 1602. Caccini hurriedly prepared the score for the press and published it six weeks before Peri's version appeared.
