Marguerite de la Sabliere (c.1636-1693), French arts patron. De la Sabliere was a friend and patron of artists, writers and scientists. The poet La Fontaine taught her philosophy and natural history, and her salon became a cultural centre in Paris. Members of the French Academy such as Joseph Sauveur and Giles de Roberval instructed her in mathematics, physics and astronomy. She attended the public lectures of Verney on anatomy, D'Alence on physics, and Roberval on calculus. She studied at the Paris Observatory under Cassini, and is considered to be one of the first woman astronomers. Her role typifies that of the 'scientific lady' at the beginning of the Enlightenment in France.
