The opera Naïs received its premiere at the Académie Royale in the Palais-Royal, Paris, on 22 April 22 1749 to celebrate the signing of the Treaty of Aix-la-Chapelle. It was revived in August 1764, shortly before Rameau's death and achieved great success as a 'peace opera'. This scholarly-critical edition, published by Pascal Denécheau in the “Opera Omnia Rameau”, is the fruit of a meticulous comparison of every known musical source. The main body of the edition presents the version pronounced valid by Rameau for the 1749 performances. The appendices contain those passages that he deleted during the 1749 rehearsals and all the changes he made for the new production of 1764. It is here, and especially in the ballets, that Rameau reveals his consummate mastery of the orchestra.<br>
