CHAPTER XII

THE ANNUAL SEASONS

The year comprises four seasons; spring, summer, autumn, and winter; of

these, the spring partakes chiefly of moisture, for on the dissipation

of cold and recommencement of warmth, an expansion of the fluids takes

place: the summer is principally hot, owing to the Sun’s nearest

approach to the zenith: the autumn is principally dry, because the

recent heat has absorbed the moisture: and the winter is chiefly cold,

the Sun being then at his farthest distance from the zenith.

The beginning of the whole zodiacal circle (which in its nature as

a circle can have no other beginning, nor end, capable of being

determined), is therefore assumed to be the sign of Aries, which

commences at the vernal equinox:[42] since the moisture of spring forms

a primary beginning in the zodiac, analogous to the beginning of all

animal life; which, in its first age of existence, abounds principally

in moisture: the spring, too, like the first age of animal life, is

soft and tender; it is therefore suitably placed as the opening of the

year, and is followed by the other seasons in appropriate succession.

The summer comes second, and, in its vigour and heat, agrees with the

second age of animals; the prime of life, and the period most abounding

in heat. Again, the age when the prime of life has passed away, and in

which decay prepares to advance, is chiefly abundant in dryness, and

corresponds to the autumn. And the final period of old age, hastening

to dissolution, is principally cold, like the winter.

[42] This sentence shows the futility of the objection raised against

astrology (and mentioned in the Preface to this translation) that the

signs have changed and are changing places. It is clear from this

sentence that Ptolemy ascribes to the 30 degrees after the vernal

equinox, that influence which he has herein mentioned to belong to

Aries; to the next 30 degrees, the influence herein said to belong to

Taurus; and so of the rest of the zodiac. We should rather say that

the stars have changed places, than that the parts of heaven, in which

they were once situated, have done so. Ptolemy himself seems to have

foreseen this groundless objection of the moderns, and has written, in

the 25th chapter of this book, what ought completely to have prevented

it. It has certainly been one of the misfortunes of astrology to be

attacked by people entirely ignorant of its principles.
