CHAPTER VIII

THE INFLUENCE OF POSITION WITH REGARD TO THE SUN

The respective powers of the Moon and of the three superior planets are

either augmented or diminished by their several positions with regard

to the Sun.

The Moon, during her increase, from her first emerging to her first

quarter, produces chiefly moisture; on continuing her increase from her

first quarter to her full state of illumination, she causes heat; from

her full state to her third quarter she causes dryness; and from her

third quarter to her occultation she causes cold.

The planets, when matutine, and from their first emerging until they

arrive at their first station, are chiefly productive of moisture;

from their first station until they rise at night, of heat; from their

rising at night until their second station, of dryness; and from their

second station until their occultation, they produce cold.[32]

But it is also sufficiently plain that they must likewise cause, by

their intermixture with each other, many varieties of quality in the

Ambient: because, although their individual and peculiar influence may

for the most part prevail, it will still be more or less varied by the

power of the other heavenly bodies configurated with them.

[32] Although all the positions mentioned in this paragraph are not

applicable to Venus and Mercury, which can never rise at night, that

is to say, at sunset, and although the author in the beginning of the

chapter speaks only of the Moon and the three superior planets, there

yet seems no reason why the orbits of Venus and Mercury should not be

similarly divided by their inferior and superior conjunctions, and

their greatest elongations.

The following is from Whalley: “The first station, in this chapter

mentioned, is when a planet begins to be retrograde; and the second

station when, from retrogradation, a planet becomes direct. They” (the

planets) “begin to rise at night when in opposition to the Sun.”
