Among the most famous of these mystical reformers were William Briconnet, Bishop of Meaux, and his disciple, Margaret d'Angouleme, sister of Francis I. Though a highly talented woman Margaret was weak and suggestible. She adored her dissolute brother and was always, on account of her marriages, first with Charles, duke of Alencon, [Sidenote: 1509] and then with Henry d'Albret, king of Navarre, [Sidenote: 1527] put in the position of a suppliant for his support. She carried on an assiduous correspondence with Briconnet as her spiritual director, being attracted first by him and then by Luther, chiefly, as it seems, through the wish to sample the novelty of their doctrines. She wrote _The Mirror of the Sinful Soul_ in the best style of penitent piety. [Sidenote: 1531] Its central idea is the love of God and of the "debonnaire" Jesus. She knew Latin and Italian, studied Greek and Hebrew, and read the Bible regularly, exhorting her friends to do the same. She coquetted with the Lutherans, some of whom she protected in France and with others of whom in Germany she corresponded. She was strongly suspected of being a Lutheran, though a secret one. Capito dedicated to her a commentary on Hosea; Calvin had strong hopes of winning her to an open profession, but was disappointed. Her house, said he, which might have become the family of Jesus Christ, harbored instead servants of the devil. Throughout life she kept the accustomed Catholic rites, and wrote with much respect to Pope Paul III. But fundamentally her religious idealism was outside of any confession. This mystically pious woman wrote, in later life, the _Heptameron_, a book of stories published posthumously. Modelled on the _Decameron_, it consists {190} almost entirely of licentious stories, told without reprobation and with gusto. If the mouth speaketh from the fullness of the heart she was as much a sensualist in thought as her brother was in deed. The apparent contradictions in her are only to be explained on the theory that she was one of those impressionable natures that, chameleon-like, always take on the hue of their environment.
