" You who are skilled in Alchemy, and as many others as promise yourselves great riches or chiefly desire to make gold and silver, which Alchemy in different ways promises and teaches; equally, too, you who willingly undergo toil and vexations, and wish not to be freed from them, until you have attained your rewards, and the fulfilment of the promises made to you; experience teaches this every day, that out of thousands of you not even one accomplishes his desire. Is this a failure of Nature or of Art? I say, no; but it is rather the fault of fate, or of the unskilfulness of the operator..."

The Coelum Philosophorum, or book of vexations; the science and nature of alchemy, and what opinion should be formed thereof. Regulated by the seven rules or fundamental canons according to the seven commonly known metals; and containing a preface with certain treatises and appendices.

Acclaimed by Publishers Weekly as "a classic reference, dizzying in its breadth," this volume explores the themes underlying ancient mythology, philosophy, and religion. Hundreds of entries range from esoteric elements of Islamic and Christian history to arcane rituals practiced by Druids, Freemasons, alchemists, and other secret societies. 16 pages of color plates, 100 black-and-white illustrations.

How can we account, in a rigorous way, for alchemy's ubiquity? We think of alchemy as the transformation of a base material (usually lead) into gold, but "alchemy" is a word in wide circulation in everyday life, often called upon to fulfill a metaphoric duty as the magical transformation of materials. Almost every culture and time has had some form of alchemy. This book looks at alchemy, not at any one particular instance along the historical timeline, not as a practice or theory, not as a mode of redemption, but as a theoretical problem, linked to real gold and real production in the world. What emerges as the least common denominator or "intensive property" of alchemy is ambivalence, the impossible and paradoxical coexistence of two incompatible elements. Alchemical Mercury moves from antiquity, through the golden age of alchemy in the Dutch seventeenth century, to conceptual art, to alternative fuels, stopping to think with writers such as Dante, Goethe, Hoffmann, the Grimm Brothers, George Eliot, and Marx. Eclectic and wide-ranging, this is the first study to consider alchemy in relation to literary and visual theory in a comprehensive way.
