The Sphere of the World (1482) - Page 5

A horizontal view shows the closed book's fore-edge—the side of the page block opposite the spine. The gathered pages appear as a solid, slightly textured surface in shades of tan and yellowish-brown, a coloration typical of paper that has aged over centuries. Along the top and bottom of this page block, the edges of the front and back covers are visible, showcasing a marbled paper pattern composed of swirling ochre, forest green, and terracotta pigments. The volume is resting on a dark, non-reflective surface.
