Isidore Kozminsky, The Magic and Science of Jewels and Stones
“ The general opinion now is that the stone described by Pliny under the name of LYCHNIS is our tourmaline. Pliny writes in his 37th Book on Natural History of the power of the LYCHNIS of drawing straws and fluff towards it when heated by the sun or by the friction of the hand.The peculiar attractive and repulsive properties of the tourmaline may be compared with the mysteries contained in the caduceus of the wise and ever-restless Hermes. The symbolical snakes which adorn the rod represent knowledge received and knowledge imparted in the hermetic scheme of the Rosicrucians. ”
