This important survey of alchemical symbols and doctrines sets forth the mysterious worldview and teachings of the practitioners of the royal art. One of the leading exponents of the Hermetic tradition Julius Evola demonstrates the singularity of subject matter that lies behind the words of all adepts in all ages showing how alchemy--often misunderstood as primitive chemistry or a mere template for the Jungian process of individuation --is nothing less than a universal secret science of human and natural transformation. First published in 1931 in Italian. This is the first English translation. Draws from a host of sources in the Western esoteric tradition--works on theurgy magic and gnosticism from neoplatonic Arab and medieval sources.
