Then he pointed out the _Hexameron_ of Torquemada and the _Tableau de l’Inconstance des Démons_, by Delancre; he drew his finger down the leather back of Delrio’s _Disquisitiones Magicae_ and set upright the _Pseudomonarchia Daemonorum_ of Wierus; his eyes rested for an instant on Hauber’s _Acta et Scripta Magica_, and he blew the dust carefully off the most famous, the most infamous, of them all, Sprenger’s _Malleus Malefikorum_. “Here is one of my greatest treasures. It is the _Clavicula Salomonis_; and I have much reason to believe that it is the identical copy which belonged to the greatest adventurer of the eighteenth century, Jacques Casanova. You will see that the owner’s name had been cut out, but enough remains to indicate the bottom of the letters; and these correspond exactly with the signature of Casanova which I have found at the Bibliothéque Nationale. He relates in his memoirs that a copy of this book was seized among his effects when he was arrested in Venice for traffic in the black arts; and it was there, on one of my journeys from Alexandria, that I picked it up.” He replaced the precious work, and his eye fell on a stout volume bound in vellum. “I had almost forgotten the most wonderful, the most mysterious, of all the books that treat of occult science. You have heard of the Kabbalah, but I doubt if it is more than a name to you.” “I know nothing about it at all,” laughed Susie, “except that it’s all very romantic and extraordinary and ridiculous.” “This, then, is its history. Moses, who was learned in all the wisdom of Egypt, was first initiated into the Kabbalah in the land of his birth; but became most proficient in it during his wanderings in the wilderness. Here he not only devoted the leisure hours of forty years to this mysterious science, but received lessons in it from an obliging angel. By aid of it he was able to solve the difficulties which arose during his management of the Israelites, notwithstanding the pilgrimages, wars, and miseries of that most unruly nation. He covertly laid down the principles of the doctrine in the first four books of the Pentateuch, but withheld them from Deuteronomy. Moses also initiated the Seventy Elders into these secrets, and they in turn transmitted them from hand to hand. Of all who formed the unbroken line of tradition, David and Solomon were the most deeply learned in the Kabbalah. No one, however, dared to write it down till Schimeon ben Jochai, who lived in the time of the destruction of Jerusalem; and after his death the Rabbi Eleazar, his son, and the Rabbi Abba, his secretary, collected his manuscripts and from them composed the celebrated treatise called _Zohar_.” “And how much do you believe of this marvellous story?” asked Arthur Burdon.
