The title and description of the book give an idea that the book does not live up to. The subtitle is: “The Mystical Islamic Essence of the Sacred Art of Alchemy” and the description suggests that the book presents a Traditionalistic approach to shed light on the Islamic history of alchemy. As I said, that is not exactly what the book delivers.
The book is only 136 and already on page 65 the appendices start. Up until then you mostly get biographies of Sufis. All of them undoubtedly had something with alchemy, but Eberly’s book reads more like a book about Sufism (or rather: Sufis) than a book on alchemy. The biographies are mostly just that, they give an idea of the lives of the men, but not too much about their thoughts. This may be interesting in a way, but not what I hoped for.
One appendix is an alchemical recipe, then follows the Emerald Tablet and after that a lengthy glossary of Islamic mystical and alchemical terms. This is actually a nice extra, but I would have preferred it had the book stayed closer to the subject.
