How did celestial divinities contribute to the development of astrology?

Celestial divinities were fundamental to the development of astrology, as ancient cultures perceived the Sun, Moon, and planets as powerful, knowledgeable deities. In early Mesopotamia, these celestial bodies were believed to send signs or omens to warn kings and kingdoms of impending events, such as harvests, epidemics, or war.1234

Because the Sun and Moon were seen as having the power of gods, it was a natural progression for ancient observers to attribute similar divine influence to the other "wanderers" (the planets) moving through the zodiac. This belief system evolved from state-level omen-taking into personal astrology, where the positions of these planetary deities at the time of an individual's birth were thought to indicate their fate.24

In various traditions, such as those of the Hindus or the Harranians, planets were explicitly regarded as potent deities whose decrees could be influenced through puja or other forms of supplication. Thus, the transition from observing celestial objects as divine entities to interpreting their movements as a system of influence was a primary driver in the history of astrological practice.512
