Johann Thölde & Basil Valentine 
The Twelve Keys of Basil Valentine 
Concerning The Great Stone of the Ancient Sages. Original 1599 Edition

One of the most well known books on alchemy, The Twelve Keys of Basil Valentine,  is a allegorically encrypted set of instructions on how to create the philosopher’s stone, a legendary substance that can turn base metals into gold. Some say the philosopher’s stone is actually a reference to the recipe for immortality. 



The magical substance or how to create it has been searched for by such great minds as Sir Isaac Newton and has inspired popular culture for years.
