The Sophic Hydrolith, or Waterstone of the Wise, is an influential alchemical text that compares the alchemical process with that of the Gospels of Christ. Through the analogy of christ, the work describes the process of obtaining, and more importantly, the application of the Philosopher’s Stone.
The document had a long publishing history, first printed in German by Johann Ambrose Siebmacher in 1619 before being republished multiple times all the way up into the 19th century.
Jones has included a foreword introducing the text and diligently footnoted the work to give meaning and context to the original writing.
