You could say Abraham was the end of Taurus, his grandfather was a bull like character. Nahor means snorter, like a bull or a horse snorting. But I don't think Biblical astrology is always that direct, it's the framework of the stories that is astrological.

Here's how I look at it: The OT books were based on older material, records kept by priests. the primary job of priests was to keep the calendar, essential for an agricultural society. From Mesopotamia, there's lots of tablets that are just record keeping of star location and celestial events. Within those records they also wrote down political events, and the results of haruspices, which were liver readings. They'd examine the liver of a sacrificed animal, to give omens about impending battles etc. Such records are the most likely source material for 1st & 2nd Kings, and 1st & 2nd Chronicles, 1st & 2nd Samuel, and even Judges. So, those books are all laced with astrology, because of their origin material.

Then, there's just the basic astrology of ancient story telling, it's a well studied aspect of The Epic of Gilgamesh. The events of the story can be traced through the stars, in the sequence of the Zodiac, through the year. That's not controversial, it's accepted by academia. The same is probably true for The Iliad, but I haven't made a study of it. It makes a lot of sense for oral traditions to use the stars, because it helps with memorization. I've identified the same astrological sequence in the story of Moses and Judges is a really obvious star story. And, the story of Jesus follows the same format.

I avoid talking about such things too much around here because it's likely to piss off some Christians. But it is very interesting and I don't think it takes anything away from Christianity.

BTW: Abram is the contraction of abba and ram, which means father thunder. He's Zeus, aka Baal. The Christian interpretation of being the spiritual children of Abram, rather than jews being his genetic offspring, makes perfect sense when you understand Abram was Zeus.
