Twelve centuries later we find Philo’s association of politicians with magicians repeated by his compatriot Moses Maimonides in the _More Nevochim_ or _Guide for the Perplexed_,[1597] a work which appeared almost immediately in Latin translation and from which this very passage is cited by Albertus Magnus in his discussion of divination by dreams.[1598] There are some men, says Albert, in whom the intellect is abundant and active and clear. Such men are akin to the superior substances, that is, to the angels and stars, and therefore Moses of Egypt, _i.e._, Maimonides, calls them sages. But there are others who, according to Albert, confound true wisdom with sophistry and are content with mere probabilities and imaginations and are at home in “rhetorical and civil matters.” Maimonides, however, described this class a little differently, saying that in them the imaginative faculty is preponderant and the rational faculty imperfect. “Whence arises the sect of politicians, of legislators, of diviners, of enchanters, of dreamers, ... and of prestidigiteurs who work marvels by strange cunning and occult arts.”[1599] CHAPTER XV THE GNOSTICS Difficulty in defining Gnosticism—Magic and astrology in Gnosticism—Simon Magus as a Gnostic—Simon’s Helen—The number thirty and the moon—Ophites and Sethians—A magical diagram—Employment of names and formulae—Seven metals and planets—Magic of Simon’s followers—Magic of Marcus in the Eucharist—Other magic and occult lore of Marcus—Name and number magic—The magic vowels—Magic of Carpocrates—The Abraxas and the number 365—Astrology of Basilides—_The Book of Helxai_—Epiphanius on the Elchasaites—_The Book of the Laws of Countries_—Personality of Bardesanes—Sin possible for men, angels, and stars—Does fate in the astrological sense prevail?—National laws and customs as a proof of free will—_Pistis-Sophia_; attitude to astrology—“Magic” condemned—Power of names and rites—Interest in natural science—“Gnostic gems” and astrology—The planets in early Christian art—Gnostic amulets in Spain—Syriac Christian charms—Priscillian executed for magic—Manichean manuscripts—The Mandaeans.
