From late 1687 to early 1698, Charpentier served as "maître de musique" (music master) to the Jesuits, working first for their "collège" of Louis-le-Grand (for which he wrote "David et Jonathas" and where he was still employed in April 1691) and then for the church of Saint-Louis adjacent to the order's professed house on the rue Saint-Antoine. Once he moved to Saint-Louis, Charpentier virtually ceased writing oratorios and instead primarily wrote musical settings of psalms and other liturgical texts such as the Litanies of Loreto. During his years at Saint-Louis, his works tended to be for large ensembles that included paid singers from the Royal Opera. In addition, during these years Charpentier succeeded Étienne Loulié as music teacher to Philippe, Duke of Chartres.
