1. The Egyptians were the first to discover astronomy. And the
Chaldeans first taught astrology and the observance of nativity.
Moreover, Josephus asserts that Abraham taught astrology to the
Egyptians. The Greeks, however, say that this art was first
elaborated by Atlas, and therefore it was said that he held the
heavens up.
2. Whoever was the discoverer, it was the movement of the heavens
and his rational faculty that stirred him, and in the light of the
succession of seasons, the observed and established courses of the
stars, and the regularity of the intervals, he considered carefully
certain dimensions and numbers, and getting a definite and distinct
idea of them he wove them into order and discovered astrology.
