This is TASCHEN's 25th anniversary - special edition! The Hermetic Museum takes its readers on a magical mystery tour spanning an arc from the mediaeval cosmogram and images of Christian mysticism, through the fascinating world of alchemy to the art of the Romantic era. The enigmatic hieroglyphs of cabbalists, Rosicrucians and freemasons are shown to be closely linked with the early scientific illustrations in the fields of medicine, chemistry, optics, and color theory.
