Book: The Pictorial Symbols Of Alchemy by Arthur Edward Waite
Waite, first in "The Key to the Tarot" (p.74), and again in "The Pictorial Key to the Tarot" (p. 61), writes "The spiritual side of Alchemy is set forth in the much stranger emblems of the Book of Lambspring, and of this I have already given a preliminary interpretation, to which the reader may be referred." Here is the article to which he refers. From "The Occult Review", vol. 8, no. 5, November 1908.Free eBooks (Can Be Downloaded):
