     Diuturna observatione deprehenderunt astronomi, caelos inferiores non moveri ab occasu in ortum super polos mundi, et per circulum aequinoctialem, sed super polos distinctos, nempe super zodiaci, et per circulum zodiacum.

     By long observation, astronomers have discovered that the lower heavens do not move from west into the east upon the world's poles and through the circle of the equinox, but upon different poles, specifically the poles of the zodiac, and through the zodiac circle.
