This new and completely redesigned edition creates a colourful and vibrant guide to the secret art. Klossowski de Rola elucidates the mysterious language and polyvalent symbolism from a variety of perspectives – practical, spiritual, elemental and historical – and explains how the true alchemist differs from the modern chemist and the false practitioner. Gold is only a by-product and emblem of the Great Work of the alchemist. The latter part of the book comprises the full text of a seventeenth-century exposition upon an alchemist’s dream-poem, and five richly illustrated ‘Themes’ sections, reproducing full sequences of alchemical thought, art and paraphernalia.
