NOw we shall have the Planets powerfull when they are ruling in a House, or in Exaltation or Triplicity, or term, or face without combustion of what is direct in the figure of the heavens, viz when they are in Angles, especially of the rising, or Tenth, or in houses presently succeeding, or in their delights. But we must take heed that they be not in the bounds or under the dominion of Saturn or Mars, least they be in dark Degrees, in pits or vacuityes. Thou shalt ocserve that the Angles of the Ascendent, and Tenth and Seventh be fortunate, as also the Lord of the Ascendent and place of the Sun and Moon, and the place of part of the fortune, and the Lord thereof, the Lord of the foregoing Conjunction & prevention: But that they of the malignant Planet fall unfortunate, unless haply they be significators of thy work, or can be any way advantagious to thee; or if in thy revolution or birth, they had the predominancy; for then they are not at all to be depressed. Now we shall have the Moone powerful if she be in her house, or exaltation, or triplicity, or face, and in degree convenient for the desired work, and if it hath a mansion of these twenty and eight sutable to it self and the work; Let her not be in the way burnt up, nor slow in course; let her not be in the Ecclipse, or burnt by the Sun, unless she be in unity with the Sun; let her not descend in the Southern latitude, when she goeth out of the burning, neither let her be opposite to the Sun, nor deprived of light, let her not be hindred by Mars, or Saturn. I will not here discourse any longer of these, seeing these, and many more necessary things are sufficiently handled in the Volums of Astrologers.
