In 1765, as the result of the Will of Honoré Armand de Villars, a new drawing school was established which became known as the Aix Drawing School (École de dessin d'Aix-en-Provence), with the painter Charles Marcel Aune as its first principal and Arnulphy as his deputy. In 1785, Aune resigned the headship of the school to travel to North America, and Arnulphy took over from him. However, being by then aged at least eighty-eight, he chose a successor in the shape of a much younger man, Jean-Antoine Constantin.
