The Ouverture matches the overture of Rameau's La naissance d'Osiris (1754): incipit 1.2.1 of the score F-Pn VM2-311 and the first incipit of the parts F-Pn VM2-323, rhythm included. A Rameau harpsichord arrangement (840026887) says the piece was that overture. The anonymous record names Rameau only for the Vivement (La Pantomime), not for the overture.
