Cosmographiae introdvctio : cum quibusdam geometriae ac astronomiae principijs ad eam rem necessarijs
Cosmographiae introdvctio is a 1533 Venetian cosmography and astronomy primer by Peter Apian, printed for Melchior Sessa and aimed at students learning geometry and the heavens. Its pictures are small woodcut diagrams of armillary spheres, celestial circles, and sighting instruments, drawn with bold outlines, clear labels, and simple shading that a designer could borrow for schematic or scientific graphics.
