OF THE OBSERVATION OF THE CELESTIALS NECESSARY IN EVERY MAGICAL WORK.
EVERY natural virtue works things far more wonderful when it is not only compounded of a natural proportion, but also is informed by a choice observation of the celestials opportune to this (viz. when the celestial power is most strong to that effect which we desire, and also helped by many celestials), by subjecting inferiors to the celestials, as proper females, to be made fruitful by their males. Also, in every work there are to be observed the situation, motion, and aspect of the stars and planets, in signs and degrees, and how all these stand in reference to the length and latitude of the climate; for by this are varied the qualities of the angles, which the rays of the celestial bodies upon the figure of the thing describe, according to which celestial virtues are infused. So when you are working any thing which belongs to any planet, you must place it in its dignities fortunate, and powerful, and ruling in the day hour, and in the figure of the heavens. Neither must you expect the signification of the work to be powerful, but you must observe the Moon opportunely directed to this; for you shall do nothing without the assistance of the Moon. And if you have more patterns of your work, observe them all, being most powerful, and looking upon one another with a friendly aspect; and if you cannot have such aspects, it will be convenient at least that you take them angular. But you shall take the Moon either when she looks upon both, or is joined to one, and looks upon the other, or when she passes from the conjunction or aspect of one, to the conjunction or aspect of the other; for that, I conceive, must in no wise be omitted. Also, you shall in every work observe Mercury, for he is a messenger between the higher gods and the infernal gods: when he goes to the good, he increases their goodness--when to the bad, he hath influence on their wickedness. We call it an unfortunate sign or planet, when it is, by the aspect of Saturn or Mars especially, opposite or quadrant, for these are the aspects of enmity; but a conjunction, a trine, and a sextile aspect, are of friendship; between these there is a greater conjunction; but vet if you do already
behold it through a trine, and the planet be received, it is accounted as already conjoined. Now all planets are afraid of the conjunction of the Sun, rejoicing in the trine, and sextile aspect thereof.
