In "The Economy of Minerals," Paracelsus explores mineralogy and alchemy, elucidating the genesis, transformation, and ultimate matter of minerals. This work, translated by A.E. Waite and edited by Christopher Templesage, provides an examination of alchemical processes and natural philosophy. Paracelsus’s insights into the elemental composition and transmutation of minerals offer invaluable knowledge to both historical and contemporary scholars of alchemy and natural sciences. This edition preserves the depth of Paracelsus’s original treatise, presenting it as an essential text for understanding the confluence of alchemy, mineralogy, and early modern scientific thought.
