are the Effects of Artificial Magick less wonderful, not only in respect of its Predictions observable in Judiciary Astrology, Agriculture, Medicine, the Art of Navigation, and others, grounded upon very probable Conjectures, but also of its ope∣rations, as well true as false, or illusory. The true ones are grounded on the Principles of the Mathematicks, especially on those of the Mechanicks, which are the noblest and most ne∣cessary part thereof, and on which do depend all the Water-Engines, Machins moving of themselves, and other Inventions wherewith the Ancients wrought such Effects as were accounted miraculous. Such were, that Man's Head of brass made by Al∣bertus Magnus, which fram'd an articulated Man's Voice, in imi∣tation of that of Memnon; the glazen Sphere of Archimedes, the motions whereof naturally represented those of the Celestial Orbes; his Burning-glasses, wherewith he burnt the Fleet of the Romans, who besieg'd the City of Saragossa where he then was; the wooden Dove of Archytas, which flew up and down with the other Doves; as did the little Birds of Boëtius made of Copper, which had this further advantage, that they could sing melo∣diously; as could also those which the Emperour Leo caus'd to be made of Gold; Malleable Glass, and such other admirable Effects of this Art, for that reason called by Hero, Thaumaturgica. Those which it produces by illusion and jugling, depend on some sleightness of hand, and cousening tricks, such as are us'd by the Professors of Legerdemain, to delude our Senses, and make things appear otherwise than they are. Such a performance was that mention'd by Josephus, in the xviii. Book of his Antiquities, used by that false Messias, Barchochabas, who to gain himself the esteem of the true one, had the knack of vomiting flames of Fire out of his Mouth as he spoke, by means of a lighted piece of Towe, which he could order as occasion serv'd; which trick, such another Impostor shew'd more cleverly, by means of a nut-shell fill'd with Brimstone and Fire. And it is a thing now gene∣rally known, that, by certain Artifices no way diabolical, one may make a company of people sitting at the Table look as if they were dead, or like so many Tawny-Moors; nay, if we be∣lieve Pliny, in the xxviii. and xxxv. Books of his History, they may be made to look as if they had the Heads of Asses or Horses.
The Second said, That, according to the Doctrine of Paganism, re-advanc'd since the Light of Christianity by the Marcionites and the Manichees, as there were two Gods, one called Oromazus, the Author of all good, who was the Sun; the other, Arimanes, Authour of all mischief; so there were two kindes of Magick whereof one, consisting of an exact knowledge, and application of things in order to a good end, is commend∣able, and known by the simple denomination of Magick, which they affirm to be an invocation of those Genii, who are our Guardians and Benefactors, in order to the procuring of
