Sphaera mundi
Sphaera mundi is a 1519 Venetian cosmography text by Johann Peurbach, printed by Jacobus Pentius de Leucho and held by the John Carter Brown Library, aimed at students of astronomy. Its pictures are simple woodcut diagrams of concentric spheres, horizon lines and labelled circles, with bold outlines and minimal shading, offering a designer clear, schematic geometry for diagrammatic or cosmic motifs.
