Section III – Chapter XIV
Wherefore, if any planet is in an angle or succedent house from the Ascendant
of the preventional conjunction, make him your significator and then see what
commixture he has with Saturn and Mars or either of them alone; for if he is in
a square of Mars or opposition or conjunction, and Mars is in a fiery sign then
the heat in the summer shall be augmented, and in winter the cold abated. Also,
if the commixture with him is by a sextile or trine, and Mars is in a fiery sign he
denotes the same but not so effectually.
Also, if its commixture is with Saturn by conjunction, square or opposition, and
Saturn is in cold, watery or earthy signs then the cold in winter shall be
increased and the heat in summer diminished. If it is by
sextile or trine and Saturn is in any of the aforesaid signs then he shall signify
the same, but not so powerfully. If Saturn is in airy signs which are hot and
moist, and the commixture with the significator is by a conjunction, square or
opposition, then it signifies the air shall be temperate and good; and if by sextile
of trine it shall be better.
If Mars has a commixture with the significator and he is in earthy signs which
are cold and dry, or in watery which are cold and moist, and it is by
conjunction, square or opposition the air will be good and temperate; but if by
sextile or trine it will be much better and will more effectually produce the
fruits and seeds of the earth.
[How to take the Part of Air or Weather according to Haly]
See also in the aforesaid figure of the conjunction you have chief regard to the
Part of Air or Weather, 1
and make it participate in judgment with your
significator. And if you find Saturn or Mars after the same manner placed and
in aspect therewith then judge according as you have heard of the significator.
You are to take this Part from the place and degree wherein Mercury is, if he is
not in his own house, to the degree of the Lord of the house wherein he is and
to which you must yet add the degree ascending, and so project it from the

The Lot of Air (or Weather) is another of the Lots specifically used in mundane weather
considerations. Al Biruni wrote of these Lots, «This matter of the casting lots is a very long one, so
that one might think there is no end to it. For instance there are those which are cast at the turn of the
year (the entry of the Sun into Aries) on worldly matters and affairs of empire, and those which are
cast at the conjunctions and oppositions of the Moon to elicit prognostics as to the weather, as to
success of ventures and other horary questions.» Cf [477] – The Book of Instruction in the
Elements of the Art of Astrology – by Al Biruni, translated by Ramsay Wright (1934) and published
by Ascella. See also Appendix III for these additional Lots used in mundane weather forecasting.
