The Magus/Book 1/Part 2/Chapter 34

SO great is the extent, power, and efficacy of the celeftial bodies, that not only natural things, but alfo artificial, when they are rightly expofed to thofe above, do prefently fuffer by that moft potent agent, and obtain a wonderful life. The magicians affirm, that not only by the mixture and application of natural things, but alfo in images, feals, rings, glaffes, and fome other inftruments, being opportunely framed under a certain conftellation, fome celeftial illuftration may be taken, and fome wonderful thing may be received; for the beams of the celeftial bodies being animated, living, fenfual, and bringing along with them admirable gifts, and a moft violent power, do, even in a moment, and at the firft touch, imprint wonderful powers in the images, though their matter be lefs capable. Yet they beftow more powerful virtues on the images if they be framed not of any, but of a certain matter, namely, whofe natural, and alfo fpecifical virtue is agreeable with the work, and the figure of the image is like to the celeftial; for fuch an image, both in regard to the matter naturally congruous to the operation and celeftial influence, and alfo for its figure being like to the heavenly one, is beft prepared to receive the operations and powers of the celeftial bodies and figures, and inftantly receives the heavenly gift into itfelf; though it conftantly worketh on another thing, and other things yield obedience to it.
