Cosmographiae introductio cum quibusdam geometriae ac astronomiae principiis ad eam rem necessariis
Peter Apian's introductory textbook on cosmography, printed in Venice in 1541 by Giovanni Antonio Nicolini da Sabbio for students needing the geometry and astronomy behind map-making. Small woodcut diagrams sit in the text: armillary spheres, horizon circles, zodiac signs, graduated arcs and stars, offering compact circular motifs and astronomical symbols usable at badge or ornament scale.
