"Of Natural and Supernatural Things" by Basilius Valentinus is a philosophical treatise that delves into alchemy, particularly the nature of metals and minerals, written in the late 17th century. The work juxtaposes the natural and supernatural realms, exploring the spiritual essence of metals and how they can be transformed through various alchemical processes. Valentinus, a Benedictine monk, seeks to reveal the hidden mysteries behind these transformations, intertwining scientific inquiry with theological reflections. The opening portion introduces the themes of duality between the natural and supernatural, explaining that everything consists of a visible, tangible element as well as an intangible, spiritual essence. Valentinus articulates various biblical instances of supernatural acts to establish a foundational understanding of his subject matter. The text sets the stage for a deep dive into the alchemical processes surrounding the "first Tincture," or essence, of metals, signifying how this transformative power can lead to both physical and spiritual enlightenment. Overall, the beginning establishes a mystical perspective on the significance of chemical transformations and their relationship with divine creation. (This is an automatically generated summary.)
