Once upon a time science, magick and religion were all viewed as being inextricably bound together. Astrology and astronomy were once considered part an parcel of the same pursuit.
In mediaeval times, one of the primary instruments for studies in this area was the astrolabe which allowed one to find constellations in the sky, determine when the sun would rise, etc. They include zodiacal designations as well. This device in turn wound up as the inspiration for the an instrument created by by Benedictine monk, John Westwyk which he described and explained the use of in Equatorie of the Planetis. The Cambridge University Library has posted the original text, a virtual working model of the device and a detailed discussion of both, Westwyk, etc. Have fun!
