CLAUDIUS PTOLEMY:

TETRABIBLOS

OR THE QUADRIPARTITE MATHEMATICAL TREATISE

8. Of the Power of the Aspects to the Sun.

Now, mark you, likewise, according to their aspects to the sun, the moon and three of the planets experience increase and decrease in their own powers. For in its waxing from new moon to first quarter the moon is more productive of moisture; in its passage from first quarter to full, of heat; from full to last quarter; of dryness, and from last quarter to occultation, of cold. The planets, in oriental aspects only, are more productive of moisture from rising to their first station, of heat from first station to evening rising, of dryness from evening rising to the second station, of cold from second station to setting; and it is clear that when they are associated with One another they produce very many variations of quality in our ambient, the proper force of each One for the most part persisting, but being changed in quantity by the force of the stars that share the configuration.
