Philidor’s Tom Jones is representative of the continental interest in English literature. Henry Fielding’s homonymous novel served as the foundation for Philidor’s opera, but Philidor pared down the story quite a bit, especially downplaying Tom’s philandering ways. Many secondary characters and situations were also cut, a common technique that librettists employ when adapting prose writings to the stage. Thus, a central plot unfolds in a manner that the audience can follow, and the length remains manageable for an evening’s entertainment.

This is a 1766 copy of the libretto of the one-act comic opera "Le cadi dupé" (The duped judge), by Pierre René Lemonnier to music by Pierre-Alexandre Monsigny. The first performance of the opera took place at the Paris Foire St-Germain on 4 February 1761. Christoph Willibald Gluck's music replaced that of Monsigny's for the 8 December 1761 performance at the Burgtheater in Vienna.
