Cosmographiæ introductio : cum quibusdam geometriæ ac astronomiæ principijs ad eam rem necessarijs
Cosmographiæ introductio is a 1533 Latin cosmography textbook by the German mathematician Peter Apian, printed in Venice by Giovanni Antonio and brothers de Sabio for the bookseller Melchior Sessa, teaching geometry and astronomy as foundations of cosmography. Its woodcut diagrams are plain line drawings of spheres, circles, zodiac bands and sightlines, with letter labels and printed captions, offering a designer clean geometric schematics of early astronomical instruments and celestial models.
