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 is a seminal work of alchemical literature attributed to Basilius Valentinus, a legendary figure in the history of alchemy. This comprehensive treatise delves into the mysterious interplay between the natural and supernatural realms, exploring the hidden forces that govern the transformation of matter. The book is structured as a series of discourses that reveal the secrets of nature, focusing particularly on the origins, properties, and transmutations of metals and minerals.

He discusses the root and spirit of metals, offering insights into their conception, generation, and augmentation through both natural and supernatural means. The text is rich with allegorical language, symbolic imagery, and practical instructions, reflecting the esoteric traditions of medieval and Renaissance alchemy. Readers are guided through the processes by which base metals may be purified and ennobled, hinting at the legendary Philosopher's Stone and the quest for spiritual enlightenment. Throughout the book, Valentinus emphasizes the interconnectedness of the physical and spiritual worlds, suggesting that true knowledge arises from understanding both. He explores the role of celestial influences, the virtues of various minerals, and the transformative power of the alchemist's art. The work is not only a manual for the aspiring alchemist but also a philosophical meditation on the nature of creation, change, and the pursuit of wisdom. Of Natural and Supernatural Things remains a fascinating window into the mindset of early modern alchemists, blending practical experimentation with mystical speculation. It continues to captivate readers interested in the history of science, esotericism, and the perennial quest to unlock the secrets of nature.
