This book was a splendid exposition of alchemy, aimed to be a primer to the art. It explains the phases, history, and barebones concepts of the royal art. It builds up to a small treatise on spagyric tinctures, so that the reader can explore first hand alchemical processes within the context of outer alchemy, using plants to connect with planetary forces.
