He had visited the greater part of the world then known; and resided for many years at the court of the sultan of that hoary Egypt, which still retained its fame for abstruse science and magic lore. He had not in vain applied himself to such tempting and wild researches; and had acquired many of those secrets now perhaps lost for ever to the world. We do not mean to intimate that he attained to what legend and superstition impose upon our faith as the art of sorcery. He could neither command the elements nor pierce the veil of the future-scatter armies with a word, nor pass from spot to spot by the utterance of a charmed formula. But men who, for ages, had passed their lives in attempting all the effects that can astonish and awe the vulgar, could not but learn some secrets which all the more sober wisdom of modern times would search ineffectually to solve or to revive. And many of such arts, acquired mechanically (their invention often the work of a chemical accident), those who attained to them could not always explain, not account for the phenomena they created, so that the mightiness of their own deceptions deceived themselves; and they often believed they were the masters of the Nature to which they were, in reality, but erratic and wild disciples. Of such was the student in that grim cavern. He was, in some measure, the dupe, partly of his own bewildered wisdom, partly of the fervour of an imagination exceedingly high-wrought and enthusiastic. His own gorgeous vanity intoxicated him: and, if it be an historical truth that the kings of the ancient world, blinded by their own power, had moments in which they believed themselves more than men, it is not incredible that sages, elevated even above kings, should conceive a frenzy as weak, or, it may be, as sublime: and imagine that they did not claim in vain the awful dignity with which the faith of the multitude invested their faculties and gifts. But, though the accident of birth, which excluded him from all field for energy and ambition, had thus directed the powerful mind of Almamen to contemplation and study, nature had never intended passions so fierce for the calm, though visionary, pursuits to which he was addicted. Amidst scrolls and seers, he had pined for action and glory; and, baffled in all wholesome egress, by the universal exclusion which, in every land, and from every faith, met the religion he belonged to, the faculties within him ran riot, producing gigantic but baseless schemes, which, as one after the other crumbled away, left behind feelings of dark misanthropy and intense revenge.
