Asia has been more notorious than perhaps any other division of the globe for the vast multiplicity and variety of its narratives of sorcery and magic. I have however been much disappointed in the thing I looked for in the first place, and that is, in the individual adventures of such persons as might be supposed to have gained a high degree of credit and reputation for their skill in exploits of magic. Where the professors are many (and they have been perhaps no where so numerous as those of magic in the East), it is unavoidable but that some should have been more dextrous than others, more eminently gifted by nature, more enthusiastic and persevering in the prosecution of their purpose, and more fortunate in awakening popularity and admiration among their contemporaries. In the instances of Apollonius Tyanaeus and others among the ancients, and of Cornelius Agrippa, Roger Bacon and Faust among the moderns, we are acquainted with many biographical particulars of their lives, and can trace with some degree of accuracy, their peculiarities of disposition, and observe how they were led gradually from one study and one mode of action to another. But the magicians of the East, so to speak, are mere abstractions, not characterised by any of those habits which distinguish one individual of the human race from another, and having those marking traits and petty lineaments which make the person, as it were, start up into life while he passes before our eyes. They are merely reported to us as men prone to the producing great signs and wonders, and nothing more. Two of the most remarkable exceptions that I have found to this rule, occur in the examples of Rocail, and of Hakem, otherwise called Mocanna. ROCAIL.
