Paracelsus
Paracelsus / Goodrick-Clarke, Nicholas
Regarded today as the father of modern medicine, Paracelsus (1493-1541) was in fact much more besides. Natural scientist, philosopher, alchemist, with a deep distrust of orthodoxy and rational thought, he intermixed Christian theology with the Qabalah, believing that magic reveals the invisible influences behind things, bringing heavenly forces down to earth.
