Anima Astrologiae or A Guide for Astrologers by William Lilly 1676

The 56th is, To consider if the significator of anything shall commit his disposition or virtue to any other Planet? Whether it be to one that is Oriental or Occidental? For if he be Oriental and one of the Inferiors and direct, or if he be Occidental and one of the Superiors, and that there be not above 20 minutes between him and the Sun, he will be weak says ‘Sarcinator,’ and not perform what he shows, but hinders many things; under that impediment like a sick man whose disease has prevailed so far, that he is forced to lie by it, and cannot help himself; or a falling house which none can preserve from ruin; and so much further as such Planet shall be from the Sun, so much less shall he be afflicted. And if it be Oriental, and one of the Superiors, or Occidental, and one of the Inferiors, and not Retrograde, he shall be strong and fit to perfect what he promises; as one that hath been ill, but is more perfectly recovered, or a building which fell and is repaired, and so of all other planets so disposed.
