Alchemy: Ancient and Modern: Being a Brief Account of the Alchemistic Doctrines, and Their Relations, to Mysticism on the One Hand, and to Recent Discoveries in Physical Science on the Other Hand; Together with Some Particulars Regarding the Lives and Teachings of the Most Noted Alchemists

"Alchemy: Ancient and Modern" by H. Stanley Redgrove is a historical account written in the early 20th century. This work discusses the philosophical and experimental aspects of alchemy, examining its relationship with mysticism and recent developments in physical science. Redgrove seeks to reframe the outdated perception of alchemy as mere superstition, presenting it instead as an important precursor to modern chemistry, with valuable insights into humanity's understanding of the physical universe. The opening of the book introduces the concept of alchemy, emphasizing its dual nature as both a physical practice and a spiritual philosophy. Redgrove explains that while alchemy is often simplistically viewed as the quest to transform base metals into gold through the Philosopher's Stone, it actually represents a deeper investigation into the nature of reality. He highlights the alchemists' belief in a cosmic unity and their attempts to realize this through experimental methods, while also recognizing the significant mystical elements within their doctrines. The opening sets the stage for the subsequent exploration of the lives and teachings of notable alchemists and their contributions to chemistry and mysticism.
