Of Natural and Supernatural Things Also of the first Tincture, Root, and Spirit of Metals and Minerals, how the same are Conceived, Generated, Brought forth, Changed, and Augmented.

"Of Natural and Supernatural Things" by Basilius Valentinus is a late 17th-century exploration of alchemy, focusing on the connection between the physical world and the divine. It examines metals and minerals by combining tangible properties with a more ethereal significance. Valentinus explains how these elements are believed to grow and change and emphasizes the spiritual aspects of the transformation. Drawing from religious texts and personal study, Valentinus introduces the idea that everything has a visible component and an invisible spirit. This mix of scientific interest and religious ideas sets the story to explore the hidden truths of the "first Tincture" of metals and its pathway to spiritual understanding.
