Galileo Galilei's Systema cosmicum, printed at Leiden by Hugo's press in 1641, is a Latin dialogue weighing the Ptolemaic and Copernican models of the universe, written for scholars and natural philosophers. Its diagrams are plain geometric constructions: circles with radii and chords, arcs with lettered points, and a rolling-ball figure on a curved ramp, offering a designer clean, schematic line motifs.
