High praise that somebody said she owned two copies, one as a spare. I agree that this is a nice book to have as a reference, and I'm sure it must be the largest collection of "Hermetick" and "Alchymical" images presently available under one cover. That said, it's pretty small (although to produce this in a large volume would probably put its price out of the range of the average enthusiast), the colors are often badly reproduced, and the text is only excusable because nobody expects much in the way of text from Taschen. The main thing you have here is convenience. I have a large enough collection of books that I can track down superior examples of most of these images...but I have to track them down. With this book, I just flip through the pages. As a companion to this book I would suggest either (preferably, if you can find it) "Alchemy: the Medieval Alchemists and Their Royal Art" by Johannes Fabricius, or (failing that) "The Golden Game: Alchemical Engravings of the Seventeenth Century" by Stanislas Klossowski de Rola, for a better look at the engravings specifically. Also, "Art and Symbols of the Occult" by James Wasserman has the best color reproductions I've seen of the lavishly-painted sixteenth-century alchemical manuscript "Splendor Solis," amidst many other amusing curiosities.
