All the World's Mornings is a 1991 novel by Pascal Quignard. It is a story of the apprenticeship of Marin Marais in the house of the austere, reclusive and mysterious violist, Monsieur de Sainte-Colombe, obsessed with his late wife, and of his romantic entanglements with his master's two daughters, Madeleine and Toinette. The story is taken from an anecdote in the work of Evrard Titon du Tillet. Among the historical facts that the book outlines are Sainte-Colombe's addition of the viola da gamba's seventh and lowest string.
