CHAP. XIX.
That great Matters may be wrought by this Art, when Princes esteem and maintain it: of divers wonderful Experiments, and of strange Conclusions in Glasses of the Art perspective, &c.
HOwbeit, these are but trifles in respect of other experiments to this ef∣fect, specially when great Princes maintain and give countenance to students in those magical Arts, which in these Countries and in this Age is rather prohibited than allowed, by reason of the abuse commonly coupled therewith; which in truth is it that moveth admiration and estimation of miracu∣lous workings. As for example, if I affirm, that with certain Charms and Popish Prayers I can set an Horse or an Asses head upon a mans shoulders, I shall not be believed;* 1.1 or if I do it, I shall be thought a Witch. And yet if J. Bap. Neap. ex∣periments be true, it is no difficult matter to make it seem so; and the Charm of a Witch or a Papist joyned with the experiment, will also make the wonder seem to proceed thereof. The words used in such case are uncertain, and to be recited at the pleasure of the Witch or Cosener.* 1.2 But the conclusion of this, cut off the head of a Horse or an Ass (before they be dead, otherwise the vertue or strength there∣of will be the less effectual) and make an earthen vessel of fit capacity to contain the same, and let it be filled with the oyl and fat thereof, cover it close, and dawb it over with lome; let it boyl over a soft fire three days continually, that the flesh boyled may run into oyl, so as the bare bones may be seen, beat the hair into pow∣der, and mingle the same with the oyl; and annoint the heads of the standers by, and they shall seem to have Horses or Asses heads. If Beasts heads be anointed with the like oyl made of a mans head, they shall seem to have mens faces, as di∣vers Authors soberly affirm. If a Lamp be anointed herewith, every thing shall seem most monstrous. It is also written, that if that which is called Sperma in any beast be burned, and any bodies face therewithal anointed he shall seem to have the like face as the Beast had. But if you beat Arsenick very fine, and boyl it with a little sulphur in a covered pot, and kindle it with a new candle, the stan∣ders by will seem to be headless. Aqua composita and salt being fired in the night, and all other lights extinguished, make the standers by seem as dead. All these things might be very well perceived and known, and also practised by Jannes and Jambres.* 1.3 But the wondrous devices, and miraculous sights, and conceits, made and contained in glass, do far exceed all other; whereto the Art perspective is very necessary. For it shews the illusions of them, whose experiments be seen in divers sorts of Glasses; as in the hollow, the plain, the embossed, the columnary, the pyramidate or piked, the turbinal, the bounched, the round, the cornered, the inversed, the eversed, the massie, the regular, the irregular, the coloured and clear Glasses; for you may have Glasses so made, as what image or favour so∣ever you print in your imagination, you shall think you see the same therein. Others are so framed, as therein one may see what others do in places far distant; others, whereby you shall see men hanging in the Air; others, where∣by you may perceive men flying in the Air; others, wherein you may see one coming, and another going; others, where one Image shall seem to be one hundred, &c. There be Glasses also wherein one man may see another
