A woodcut diagram illustrates cosmographical principles. On the left, a perspective diagram shows an eye at the base looking upward through a small terrestrial globe toward a larger celestial sphere. The celestial sphere contains various stars and zodiac symbols, including Pisces, Aquarius, and Aries. Lines of sight or projection connect the eye to the spheres. To the right is a large armillary-style globe representing the Earth with continents labeled: Europe, Asia, Africa, and America. This globe features a tilted axis and bands representing the equator and the ecliptic with zodiacal divisions.
