Astrologers ruled the world. Now they clatter in the back pages of second-rate magazines.

…and those of the most widely read daily newspapers.

I think in ancient Greece Divine would best be described as perfect and incorruptible. With the exception of the planets the stars are permanent and fixed which makes them divine. This might explain why there’s no concept of variable stars in ancient Greece, even though something like Algol would be visibly variable to the naked eye. Gods also have this same attribute of having incorruptible bodies, which makes them divine. Then ideas of divinity in gods feedback in some ways to planets, though in the case of Greek astrology the gods remained anthropomorphic.

What the planets had was κοσμος, or order. For some Greeks justice was as much a natural force as gravity. Anaximander built a cosmology based justice being a force inherent in the universe. Many other Greeks preferred to see Justice as something given or enforced by the gods and it’s not something they have complete control over if you read things like the Iliad. The divinity of the planets placed them above earthly concerns and so they acted with complete order.

That’s not a complete overview and someone else could disagree quite strongly with it in places. Greek religion and ancient religion in general doesn’t map very neatly onto the modern concept of religion. Additionally the concept of Astrology differs greatly over the ancient period. The end of the late antique period is closer to modern times than the protohistorical period I tend to study and attitudes change. For instance in Augustan times Astrology was considered by some people to be nonsense, but then a society which spends a lot of time abusing astrologers must also be a society where there are astrologers with power and status to abuse.

That’s why I said the difference between divine planets and gods was hair-splitting. It doesn’t weaken your argument that Astrology was a product of its time and needs to be evaluated in its social context rather than as a science.
