When any two of these three have been noted, what kind of third is to be sought can, accordingly, be known. The anatomies of these three – peculiar to them separately – are in the other two, but in a different way, celestial, terrestrial, or microcosmic. For example, I suggest to you the sun, gold, and man’s hearts as objects to be considered by means of the laws of Anatomical Magic.
