A 1534 Latin commentary printed at Tübingen by Hulderich Morhart, written by the mathematician Johann Stoeffler on Proclus's treatise on the celestial sphere, and aimed at students of astronomy and cosmography. The pictures are simple line diagrams of horizons, zenith lines, climate zones, and concentric earth and water spheres, drawn with compass-like precision and clear lettering that a designer could borrow for technical schematic motifs.
