Question: Who wrote the pastiche featuring music by the leading French harpsichord composer of his time, as well as Handel and Vivaldi?
Context: The French Baroque composer Jean-Philippe Rameau wrote three books of Pièces de clavecin for the harpsichord.  The first, "Premier Livre de Pièces de Clavecin ", was published in 1706; the second, "Pièces de Clavessin ", in 1724; and the third, "Nouvelles Suites de Pièces de Clavecin ", in 1726 or 1727.  They were followed in 1741 by "Pièces de clavecin en concerts ", in which the harpsichord can either be accompanied by violin (or flute) and viola da gamba or played alone.  An isolated piece, "La Dauphine ", survives from 1747. The Bauyn manuscript is a manuscript currently in possession of the Bibliothèque Nationale de France in Paris (catalogue number Rés.  Vm7 674–675).  It is, along with several printed collections and the Parville manuscript, one of the most important sources for French harpsichord music of the 17th century. The Enchanted Island is a "pasticcio" (pastiche) of music by various baroque composers, including George Frideric Handel, Antonio Vivaldi, and Jean-Philippe Rameau, devised and written by Jeremy Sams after "The Tempest" and "A Midsummer Night's Dream" by William Shakespeare.  It was created by Julian Crouch and Phelim McDermott and premiered by the Metropolitan Opera on December 31, 2011, starring David Daniels, Joyce DiDonato, Danielle de Niese, Luca Pisaroni, and Lisette Oropesa.  The popular 70-year-old Spanish tenor, Plácido Domingo, played the small but important part of the sea god Neptune.  The following month a performance of the "pasticcio" was broadcast live into movie theaters across the world as part of the Metropolitan Opera Live in HD series.  In late 2012, Virgin Classics released this broadcast version on DVD.  The Met revived "The Enchanted Island" two seasons later.  Daniels, de Niese, Pisaroni, and Domingo revived their roles from the premiere.  Susan Graham assumed the role of Sycorax from DiDonato. Jean-Baptiste Cardonne (26 June 1730 – after August 1792) was a French composer, singer and harpsichordist.  Cardonne was born at Versailles, where his father was a member of the royal household.  He became a royal page, but his musical talents were soon noticed and he received tuition from the composer Colin de Blamont.  In 1745 he joined the choir of the royal chapel, where he also played the harpsichord.  His first operatic piece, "Amaryllis", premiered in 1752.  Cardonne continued to enjoy the patronage of the royal family, writing harpsichord and vocal music for them.  From 1768, he tried to establish a career as an opera composer.  His lack of success led to his return to the court, where he became "maître de la musique du roi" (master of the King's music) in 1780.  Nothing is known about Cardonne's life after the fall of King Louis XVI during the French Revolution in September 1792. The Parville manuscript is a manuscript currently in possession of the UC Berkeley Music Library (catalogue number MS-778; full number US-BEM 778).  Along with the Bauyn manuscript, it is one of the most important sources for French harpsichord music of the 17th century. The Concerti Grossi, Op. 6, or Twelve Grand Concertos, HWV 319–330, are 12 concerti grossi by George Frideric Handel for a concertino trio of two violins and violoncello and a ripieno four-part string orchestra with harpsichord continuo.  First published by subscription in London by John Walsh in 1739, in the second edition of 1741 they became Handel's Opus 6.  Taking the older concerto da chiesa and concerto da camera of Arcangelo Corelli as models, rather than the later three-movement Venetian concerto of Antonio Vivaldi favoured by Johann Sebastian Bach, they were written to be played during performances of Handel's oratorios and odes.  Despite the conventional model, Handel incorporated in the movements the full range of his compositional styles, including trio sonatas, operatic arias, French overtures, Italian sinfonias, airs, fugues, themes and variations and a variety of dances.  The concertos were largely composed of new material: they are amongst the finest examples in the genre of baroque concerto grosso. The Denis family were French harpsichord makers from the mid 16th century to the beginning of the 18th century, by which time the Blanchet family had superseded them as the main harpsichord building dynasty in Paris.  Members of the Denis family headed the instrument makers' guild for several generations, but only four harpsichords by members of the family have survived to modern times, and three spinets.  Several of the Denis instruments are signed in red chalk under the sound board with the makers name, place of construction and date, along with three five-pointed stars.  Instruments by the Denis family where in high regard well after their time, as witnessed by an entry in the "Encyclopédie Methodique" from 1785: "The best makers of ordinary harpsichords have been the Ruckers in Antwerp... and Jean Denis of Paris". 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. Jacques Champion de Chambonnières (Jacques Champion, commonly referred to as Chambonnières) (c. 1601/2 – 1672) was a French harpsichordist, dancer and composer.  Born into a musical family, Chambonnières made an illustrious career as court harpsichordist in Paris and was considered by many of his contemporaries to be one of the greatest musicians in Europe.  However, late in life Chambonnières gradually fell out of favor at the court and lost his position.  He died in poverty, but at an advanced age, and not before publishing a number of his works.  Today Chambonnières is considered one of the greatest representatives of the early French harpsichord school. Antoine Geoffroy-Dechaume (7 October 1905 in Paris – 15 April 2000) was a French musicologist, organist and harpsichordist.  As a musicologist he was considered "the leading French pioneer in the field of early music, both in the way it should be performed and in respect for the original scores of 16th, 17th and 18th century composers."  His research and writings, especially his book "The Secrets of Early Music, or the search for its interpretation" (1964), is credited as the catalyst for the revived interest in French baroque music by the classical music world during the 1970s.  He was named a Chevalier of the Légion d'honneur by the government of France.
