Section III – Chapter XIV
[Note]
Note that every planet has its own peculiar property; for the superiors are as
spirits and the inferiors as bodies of which all the corruption and generation in
the world participates by their configurations and commixtures one with
another according to the preordination and will of God.
Moreover, the radix from which you are to judge of the alteration of the air is
the Ascendant of the conjunction of prevention of the luminaries before the
ingress of the Sun into every sign. And consider the Lord also of the Ascendant
and the Lord of the place of the conjunction or prevention, for if these places
and their lords are in moist signs and Mansions then it signifies wet weather
shall follow, as also if the significator in chief is occidental, retrograde or slow
in motion it signifies rain; and so also if he is combust unless Mars hinder it, for
when he is combust he hinders and prohibits rain. Also, note that if the chief
significator is descending in latitude or in his epicycle then he signifies rain and
so contrary if he is ascending. Moreover note, that when rain is occasioned by
the signification of the infortunes, it is still hurtful; if it is Saturn, he causes
eruptions and floods of water; if Mars, he causes for the most part extraordinary
heat.
[When rain is to be expected]
Now if you would know when it is most probable and likely to rain, according
to Haly consider the chief significator of rain. For if he is in an angle from the
Ascendant or entering therein, then judge rain at that time; as also the Sun’s
ingress into the twentieth degree and one minute of Scorpio; and see what
planets signifying rain that year are received of him, and especially of the Moon
and which he is in conjunction, square or opposition with. For upon those days
wherein these configurations happen, rain is to be expected; but if these aspects
are without reception then the rain will not be of long continuance nor very
much.
[Of the state of the weather for the whole year]
Moreover, if the significator is in an angle, as has been said, and in conjunction
with the Moon then it signifies rain, thunder, lightning, earthquakes, and such
like. But if you would know what rain is to be expected for all the year, then
consider Venus, Mercury and the Moon, and if you find them all in conjunction
