Ascendant, and there shall your Part be where the number ends. But if Mercury
is in his own house then take only the sign, degree and minute wherein he is
and by adding the Ascendant and projecting it, you shall find it where your
number ends. But if God spare my life and opportunity, I shall for your benefit
and the good of posterity take some pains to deliver to you the manner and way
of taking any Part, either by night or day, belonging to any of the planets, or the
signification of any of the 12 houses, in a treatise by itself; as also the uses of
them, etc.
[How to take Pars Dierum or the Part of Days]
To be short, if you would judge of the alteration of the air for any quarter of the
year, erect your figures for the Sun’s ingress into Aries, Cancer, Libra and
Capricorn and according to the same method judge; if for any or every month,
then see when he 1 enters the first point of every sign; if for any day, consider
the Pars Dierum or Part of Days2 which is taken from the place of the Sun to
the place of Saturn, or more plainly subtract the place of Saturn from the place
of the Sun, and add the place of the Moon and see where your number of signs,
degrees and minutes ends, and there shall be your Pars Dierum; and this must
be taken at the punctual appearance of the Sun rising above our horizon.
Wherefore, if Mercury behold this Part or is corporally joined to it than that day
there shall be much wind, especially if the Moon is then also with him, and
Venus have also any aspect thereunto; for then the more assured will this
judgment be.
There is also another way to judge of the diurnal mutation of the air, which is to
observe exactly the time of the Moon’s entering into the first point of any sign.
And having erected the figure of the heavens for that moment, see what planet
aspects of is located within five degrees of the cusp thereof and make him
significator of the state of the weather during that time the Moon is in that sign
and according to his strength and configurations with the other planets judge as
you have heard according to discretion.
