Dictionary of Alchemy, by Mark Haeffner, from Aeon Books, ISBN 1904658121. This dictionary guides readers through the labyrinth of pre-Newtonian science and philosophy. It covers not only the materialist dimension of medieval alchemy, but also the inner search for the gold of mystical illumination. Jung called alchemy "the projection of a drama both cosmic and spiritual in laboratory terms." This opus alchymicum goes beyond analysis and interpretation of terms to present a harmonic, integrated vision of humanity and nature, which may help to heal the fragmented worldview of modern science.
