Paracelsus was a famous German-Swiss alchemist and physician, botanist, author of several ancient works on medicine, reformer, who established the role of chemistry in medicine.  
“The Aurora of the philosophers” is a work dedicated to the theory of physical alchemy. Paracelsus' most important legacy is his critique of the scholastic methods in medicine, science and theology. Much of his theoretical work does not withstand modern scientific thought, but his insights laid the foundation for a more dynamic approach in the medical sciences. “The Aurora of the Philosophers” has long been considered a classic among his texts, so this document makes fascinating reading for historians of science and the esoteric. Enjoy the reading.
