Ex astrologia autem cognoscitur oriens, occidens, meridies, septentrio, etiam caeli ratio, aequinoctium, solstitium, astrorum cursus; quorum notitiam si quis non habuerit, horologiorum rationem omnino scire non poterit.
By astronomy we learn the east, the west, the south and the north; also the order of the heavens, the equinox, the solstice, the course of the planets. For if anyone is unfamiliar with these, he will fail to understand the construction of clocks.
