This booklet  explores the symbolism in the famed sixteenth-century alchemical text. It is clearly written, well-informed and thoroughly researched. Moreover, it is illustrated throughout with full-colour reproductions from the Splendor Solis. Author Paul Cowlan writes and lectures on psycho-spiritual alchemy which is grounded in historical research of the original material, with a gift for making the complexities of the subject clear. At Treadwell's he gives illustrated talks and workshops on the subject, and he is author of many articles and several books. This is an expanded version of his 2016 booklet.
