The German physician, alchemist, kabbalist, and theosopher Heinrich Khunrath (ca. 1560-1605) is one of the most remarkable figures in the intellectual history of the Renaissance. His work, combining text and images in a new way, is a fusion of the contemporary currents of thought in which alchemy went hand-in-hand with philosophy and Lutheran heterodox theology. As a follower of Paracelsus, Khunrath was in search of both the secrets of nature and and the knowledge of God-the "theosophy".
