In The Secrets of Alchemy, Lawrence M. Principe, one of the world’s leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity, touching on its enduring place in literature, fine art, theater, and religion as well as its recent acceptance as a serious subject of study for historians of science. In addition, he introduces the reader to some of the most fascinating alchemists, such as Zosimos and Basil Valentine, whose lives dot alchemy’s long reign from the third century and to the present day. Through his exploration of alchemists and their times, Principe pieces together closely guarded clues from obscure and fragmented texts to reveal alchemy’s secrets, and—most exciting for budding alchemists—uses them to recreate many of the most famous recipes in his lab, including those for the “glass of antimony” and “philosophers’ tree.” This unique approach brings the reader closer to the actual work of alchemy than any other book.

From the best-selling, award-winning author of Landmarks and The Old Ways, a haunting voyage into the planet’s past and future. Hailed as "the great nature writer of this generation" (Wall Street Journal), Robert Macfarlane is the celebrated author of books about the intersections of the human and the natural realms. In Underland, he delivers his masterpiece: an epic exploration of the Earth’s underworlds as they exist in myth, literature, memory, and the land itself. In this highly anticipated sequel to his international bestseller The Old Ways, Macfarlane takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind. Traveling through “deep time”—the dizzying expanses of geologic time that stretch away from the present—he moves from the birth of the universe to a post-human future, from the prehistoric art of Norwegian sea caves to the blue depths of the Greenland ice cap, from Bronze Age funeral chambers to the catacomb labyrinth below Paris, and from the underground fungal networks through which trees communicate to a deep-sunk “hiding place” where nuclear waste will be stored for 100,000 years to come. Woven through Macfarlane’s own travels are the unforgettable stories of descents into the underland made across history by explorers, artists, cavers, divers, mourners, dreamers, and murderers, all of whom have been drawn for different reasons to seek what Cormac McCarthy calls “the awful darkness within the world.” Global in its geography and written with great lyricism and power, Underland speaks powerfully to our present moment. Taking a deep-time view of our planet, Macfarlane here asks a vital and unsettling question: “Are we being good ancestors to the future Earth?” Underland marks a new turn in Macfarlane’s long-term mapping of the relations of landscape and the human heart. From its remarkable opening pages to its deeply moving conclusion, it is a journey into wonder, loss, fear, and hope. At once ancient and urgent, this is a book that will change the way you see the world.
