Paracelsus (ca. 1493–1541)

Philippus Theophrastus Aureolus Bombastus of Hohenheim, baptised Theophrastus Bombastus of Hohenheim, called Paracelsus (ca. 1493–1541), was known not only a physician, but also as an alchemist, astrologer, mystic , lay theologian and philosopher. As a physician, his comparatively progressive approach brought him numerous successes. A sharp critic of the medical orthodoxy of his time, Paracelsus was particularly scornful of "humourism", Galen's teaching of four distinct bodily fluids determining temperament and health. Many of his works on medicine, but also philosophy and theology, were not published until after his death.
