The individualistic spirit led the Greek to make his gods take note of every action in his life, and his preordained fate might be read in the stars.--"A connecting link between the individual and the movements in the heavens was found in an element which they shared in common.

Both man and stars moved in obedience to forces from which there was no escape.

An inexorable law controlling the planets corresponded to an equally inexorable fate ordained for every individual from his birth.
Man was a part of nature and subject to its laws.

The thought could therefore arise that, if the conditions in the heavens were studied under which a man was born, that man's future could be determined in accord with the beliefs associated with the position of the planets rising or visible at the time of birth or, according to other views, at the time of conception.

These views take us back directly to the system of astrology developed by Babylonian baru priests.
