Jeanne-Marie Bouvier de la Motte-Guyon (13 April 1648 – 9 June 1717), commonly known as Madame Guyon, was a French mystic and one of the key advocates of Quietism. Quietism was considered heretical by the Roman Catholic Church, and she was imprisoned from 1695 to 1703 after publishing a book on the topic, A Short and Easy Method of Prayer.
