Our study is inspired by a drawing by the hand of Primaticcio (Inv. 8553) preserved in the Cabinet of Graphic Arts of the Louvre and acquired by the King in 1617. This drawing has been identified as a study for one of the twelve figures on the spandrels of the arcades in the Lower gallery, composed of nine muses (Venus, Juno and Minerva) erected in front of the south facade of the Pavillon des Poêles in line with the wing and the lower courtyard of the abbey, also known as the Great Lower Court then the White Horse Court, disappeared in 1750 during construction, at its location, from the Gros Pavillon, to the Château de Fontainebleau.
