Heinrich Khunrath. Amphitheatrum sapientiae aeternae solius verae. Hanover, 1609.
Heinrich Khunrath (c. 1560- 1605) was a physician, Hermetic philosopher, and alchemist whose goal was to find the secret prima materia that would lead mankind to eternal wisdom. His most famous work on alchemy is the Amphitheatrum Sapientiae Aeternae (Amphitheater of Eternal Wisdom), which was first made widely available in the present edition. It is a classic of alchemy and combines both Christianity and magic. Khunrath was a follower of Paracelsus and John Dee (1527-1608), the mathematician and occultist who was an advisor to Elizabth I. Khunrath met Dee in 1589 during a visit to the Imperial court of Rudolf II von Habsburg in Prague where Dee was languishing in gaol.
