Mr. Mathers, who is a most patient and persevering student, if not professor, of mystic lore, is at the same time a first-rate classical scholar, and a skilful interpreter of the Hebrew tongue, and his translation from the Latin, varied and improved by his own study of the original Chaldee, has produced an English version of the Kabbalah Denudata which is eloquent in its construction, true to its text, and lucid in its abstruseness. For the matter is abstruse, much of it, and some is practically incomprehensible to the beginner, to the world in general for certain, and perhaps to every one at the first glance. But it will be certainly perceived that those very portions which seem most extravagant at a first reading are just the passages from which later a light will arise and lead one on to a firm grasp of the subject. To take up this volume and read at odd moments is a useless and hopeless task; no progress will be made, at any rate at first, except by thoroughly abstracting one’s individuality from the things of common life; disappointment can only accompany superficial reading. Great credit is due to the enterprise of Mr. Redway in publishing this volume, for which no very extensive sale could have been anticipated; that he has already distributed a considerable number is matter for congratulation to himself and to the public. It is hoped that his success will induce him to publish other volumes of antique lore, of which many yet remain more or less completely ignored by the present generation. The “Siphra Dtzenioutha,” the “Idra Rabba,” and the “Idra Zuta,” included in this volume are doubtless three of the most valuable of the tracts of the Zohar, yet there are others of equal interest. The “Book of the Revolutions of Souls” is a most curious and mysterious work, and the “Asch Metzareph” is a treatise on the relations between Theosophy and the oldest alchemical ideas which are known to exist; it is a work on the Asiatic plane, on the lowest of the four kabbalistic worlds of Emanation. Beyond the limits of the Zohar proper, the “Sepher Yetzirah,” is a treatise which for interest and instruction cannot be surpassed. Mr. Mathers supplies us with an introduction to the Qabalah, which stamps him as a master of the science, and although he refers us on some pages to Ginsburg (a recognised authority), yet his remarks and explanation are more deep and thorough than those published in Ginsburg’s little English pamphlet, and are more discursive and complete. My remarks on the difficulty of our subject hardly render it necessary for me to insist on the absolute necessity of a painstaking study of this introduction, which will supply in a great measure the want of a _de novo_ education in Hebrew, and Hebrew modes of thought and expression.
