I'd like to introduce you to LJS 57, a compendium of Astronomical text in Hebrew, written in Spain around 1391. It's an interesting combination of astronomy and astrology, and illustrates how the division between "science" and "not science" was not nearly so clear in the past as it is today. It has some fantastic illustrations of constellations!
