The significance of astrology in history is underestimated because of how we regard it today but in times past its importance was right up there
Many religions came directly from asyrology..think of a time when the Sun was viewed as god and you get clever humans claiming a link..and take on attributes of the Sun....the Sun (the God or usually son of god) having 12 followers, birth on 25th December/ death / resurrection mid winter (Sun appearing to stop, die, and move again after three days) and on the cross (Sun on the Southern cross apparently?) ...and there were many "human gods" around the Mediterranean all with the attributes taken from astrology..they are there but no one cares to look.
One author, Martin Sweatman, who talks a lot about Gobeki Tepie, offers plausible evidence to support his contention that the zodiac can be seen with cave art...and he makes a most compelling case...sounds a very scientific approach in any event.
I find it interesting but dont believe there is anything to predicting future etc...but its history is well worth study.
