Jean François, a distinguished French physician, was born at Clermont in 1497. His immense general erudition, and the skill and success with which he sought to revive the study of the old Greek physicians, gained for him a great reputation, and ultimately the office of physician to the court. He practised with very great success, and at his death in 1558 left behind him an immense fortune. His principal works are, Monalopharium, sive Astralaliae genus, generalis Horiorii Structura et Usus, Paris, 1526; De Abditis rerum Causis, a work which went through thirty editions in a short time; Medicina, ad Henricum II., &c., which was also very frequently reprinted; and Consiliorum Medicinalium Liber, Paris, 1582, a work which enjoyed a similar distinction.
