Ancient observers of the stars and the heavens noted the correlation between the sun, the seasons, and the success of crops. The study of celestial events was an early step in the attempt to understand and control the uncertainties of life and became an important part of many early religions. The sun god, Ra, for example, was the most powerful of the Egyptian gods. Priests who could determine the start and end of the growing seasons, foretell the phases of the moon, and predict terrifying eclipses greatly enhanced their power in society. The power of astrologers increased when their subjects believed that the influence of the stars and planets on human affairs could be divined from celestial positions and aspects.
