“A work that edifies and entertains. . . . Chemistry is at the heart of Lawrence Principe’s effort, and his deft use of the discipline in his historical research is one of the book’s principal strengths. . . . Principe’s attempts to replicate alchemy in a modern laboratory yield strange, wondrous, and yet thoroughly explicable phenomena.”

Bookforum

“Lawrence Principe has produced a work that is eminently readable and that sacrifices none of its critical edge or erudition.  . . . It’s precisely the fact that alchemy is such an elusive target, and such a mélange of the practical and the ridiculous, the physical and the metaphysical, that makes Principe’s book so engaging. The Secrets of Alchemy is one of those rare books that, in the best possible sense, asks many more questions than it can answer, with each answered question suggesting a host of other lines of thought.”

Los Angeles Review of Books

“The absence of a modern history of alchemy that is at both scholarly and accessible has been perplexing and frustrating. But at last this gap is filled, and by one of the experts best qualified to do so. Lawrence M. Principe’s survey is not just reliable and engaging but an essential corrective to the many depictions that romanticize, misdirect, or muddy our view of what alchemy was about. Principe’s erudite demystification will enable alchemy to take its proper place as an important stage in the evolution of technology, science, and our understanding of the world.”

Philip Ball, author of Shapes: Natures Patterns: A Tapestry in Three Parts

“Making sense out of alchemy is nearly as consuming and difficult a project as making gold with it.  Lawrence M. Principe has the requisite clarity of mind and purity of heart, as well as a willingness to risk getting burned (literally!).  The Secrets of Alchemy is an eminently lucid treatment of a tenebrous subject, at once learned and reader-friendly, and enormously winning.”

John Crowley, author of Little, Big

 “The book’s greatest accomplishment is its depiction of the values and assumptions that formed the alchemical worldview, and how they preceded, coexisted with, and led to a structured scientific methodology. In the sections most entertaining for general readers, Principe recreates various alchemical recipes. As a clear elucidation of a fascinating but, by its nature, obscure topic, this book will appeal to those interested in the history of science.”

Library Journal

“With his characteristic erudition, wit, and lucid prose, Lawrence M. Principe synthesizes the explosion of new scholarship in the history of alchemy and makes it available to a wider public. This is a must-read for anyone who wants to understand the historical ideas, practices, and personalities at the heart of this centuries-old tradition, as well as the cultural forces that have shaped how we understand alchemy today.”

Tara Nummedal, Brown University

“This is a terrific book, absolutely essential for anyone interested in a historical understanding of alchemical theory and practice. Lawrence Principe masterly clears up the jumble of (mis)information that has surrounded a subject that many think they understand—when in fact they do not—and he escorts the reader back into original texts, revealing their content and purposes. There is no other book on alchemy like this.”

Bruce Moran, author of Andreas Libavius and the Transformation of Alchemy

“Lawrence M. Principe has long been at the vanguard of scholars who seek to show that, alchemists were really early chemists, not blindly struggling to turn substances into gold but operating, like scientists today, within an intellectual framework that guided their practical work. In The Secrets of Alchemy, an elegantly written summary of two decades of his own research, Mr. Principe describes this framework.”

Wall Street Journal

“Principe’s own alchemical experiments (which he undertakes following instructions from alchemical text -- albeit at times cloaked in ’allegorical’ detail he must first unravel) do provide clear substantiation of the forward-thinking functionality occurring in the historical alchemy workshop. While Principe himself never quite turns lead into gold, he nonetheless demonstrates beyond a doubt just how grounded and rigorous the practice of alchemy remains when held up against the scientific method. . . .This is a first-rate guide to the discipline while also usefully serving as a necessary reminder of the benefits brought on by a broad-encompassing and unflinching open approach towards discovery in any historical subject.”    

Bookslut

“What is alchemy? Who were the alchemists, what did they believe and do and dream, and what did they accomplish? Lawrence M. Principe’s new book explores these questions and some possible answers to them in a wonderfully written and argued introduction to the history of western alchemy. The Secrets of Alchemy traces the genealogy of alchemical practices from their early Greco-Egyptian foundations through early modern chymistry, pausing along the way to reflect on the reinterpretation and refashioning of alchemy from the eighteenth century to the present. Principe’s pages reveal histories of alchemy that are wonderfully rich and diverse, and we meet them in laboratories, recipes, images, dramatic plays, and poems.”

New Books Network

“For any self-respecting chemist or for anyone who is interested in the origins of chemistry, The Secrets of Alchemy is a must read.”

Chemistry World

“A deeply gratifying book that brilliantly unveils the hidden wonders of that most shadowy and misunderstood art.”

Times Literary Supplement

“Principe . . . combines linguistic expertise, historical subtlety, and laboratory experience to a degree that makes him one of the finest and most trustworthy exponents of the subject. . . . A triumph and by far the best available history of alchemy.”
