The Furnace and the Cosmos A Cultural History of Alchemy, from Ancient Egypt to the Modern World #1000496

Alchemy has never been only the dream of making gold. Across more than two thousand years, it has been a language of matter and transformation, a laboratory practice, a philosophy of nature, a religious metaphor, and one of the most persistent imaginative traditions of the Western world. *The Furnace and the Cosmos* traces the cultural history of alchemy from the world of ancient Egypt and Hellenistic Alexandria to the laboratories, manuscripts, courts, monasteries, and secret societies of medieval and early modern Europe. Along the way, it follows the development of the vessels, furnaces, substances, symbols, and theories through which generations of practitioners attempted to understand how matter could be purified, dissolved, recombined, and perfected. The story moves through figures such as Maria the Jewess, Cleopatra the Alchemist, Zosimos of Panopolis, Jabir ibn Hayyan, Paracelsus, and the great authors of the European alchemical tradition, while examining the transmission of alchemical knowledge through Greek, Syriac, Arabic, Latin, and vernacular texts. It explores the philosopher’s stone, the elixir of life, the relationship between metals and planets, the imagery of death and rebirth, the rise of laboratory culture, and the changing boundary between alchemy, medicine, natural philosophy, chemistry, and esotericism. Rather than treating alchemy either as primitive chemistry or as a timeless spiritual doctrine, Julian Harrowden reconstructs it as a changing historical phenomenon: a meeting point between craft, experiment, cosmology, religion, and imagination. From the fire of the athanor to the ordered movements of the heavens, *The Furnace and the Cosmos* reveals a world in which the transformation of matter could also become a way of thinking about the transformation of nature—and of humanity itself.
