The successful film Tous les matins du monde had the undisputed merit of bringing the world’s attention to the figure of Monsieur de Sainte-Colombe and to the viola da gamba in general, since Sainte-Colombe provided substantial contributions to the repertoire of this instrument. Still, the film’s plot was explicitly (and fully legitimately) grounded on a fictional work, a novel telling the history of Sainte-Colombe with references to what was, by then, known about him. Fortunately, a virtuous circle was ignited by the film, prompting new and meticulous research on his figure and effectively bringing to light some hard facts about his life.
