Teaching by other rules how to judge of the alterations of the air and to know when
rain is to be expected
You must still remember to erect your figure for the exact time for which you
require judgment, and place the planets therein being reduced to the time of day
and see what planets are then in conjunction or aspect with the Sun and Moon,
especially if the figure is made at any lunation. For if, it is Jupiter or Venus and
they corporally joined to the Sun and Moon, or Jupiter in a sextile or trine of
them, and they are then free of conjunction or aspect of all the malevolents
neither applying to them after their separation from Jupiter, it is an
assured testimony of fair weather. But if Jupiter beholds them by a square or
opposition, and they free also from the malevolent configurations of the
infortunes, as has been said, he shall denote gentle pleasant showers. But if any
of the malevolent planets, especially Saturn is in aspect with them or
conjunction, although by sextile or trine, or they apply unto him after their
conjunction, especially if by square or opposition, rain shall inevitably
follow; for it is the natural property of the malevolents to disturb and thicken
the air with offensive vapours, as it is the disposition of the fortunes to
disperse then and clear the air thereof, resisting the quality of the malevolents.
Now you must know that although Venus is one of the fortunes, yet she
disposes the air and weather to moisture by reason of her moist nature,
especially if she is in any configuration with the Sun in moist signs and
Mansions or has any commixture or participation with the malevolents; but yet
she seldom sends noisome or unseasonably wet weather unless, when she
participates with the infortunes, she is then also very weak and afflicted. For
then, she is not able to lessen their malicious influence.
If the Sun is in the south part of heaven and Venus under his beams and the
Moon is then in conjunction with either of them, especially Venus, or applying
unto her by aspect, you shall assuredly judge when that configuration is, i.e.
that very day and hour, there shall be rain and showers; and if Mercury also is
in the same part of heaven applying to the Moon by conjunction or aspect, it
shall denote rain, especially if the Moon is in Scorpio; so also, if Mars and
Venus are in conjunction, especially also in Scorpio. When the Sun is in
Aquarius and the Moon applying by opposition to him, and Venus is also
placed as aforesaid, you shall judge rain at that very hour. When Mars
