Solid Objects is a mysterious 16th-century watercolor manuscript of geometric and perspective drawings, housed in the Herzog August Bibliothek. With no known author, title page, or commentary, the manuscript offers a visually striking sequence of increasingly complex shapes — from pyramids and cubes to compound polyhedra and surreal arrangements. While its origins remain unclear, its style links it to the work of Jamnitzer, Dürer, and other Renaissance figures captivated by geometry and the divine order it was believed to reveal.

The drawings exhibit an internal logic, building from simple solids to intricate constructions that blend mathematical rigor with artistic elegance. As the figures grow more elaborate, they gain realistic staging: a grooved sphere rests on a jade-like barrel; a pastel pyramid evokes an ancient city; even a realistic lute floats above a lily pad. The final images merge sacred and secular — culminating in an open red book displaying a cross — and suggest that geometry, even in its purest forms, holds both spiritual and artistic power.
