Cosmographiæ introductio cum quibusdam geometriæ ac astronomiæ principijs ad eam rem necessarijs
Cosmographiæ introductio is a 1535 Latin cosmography and astronomy primer by Peter Apian, printed in Venice by Giovanni Antonio de Nicolini da Sabbio at the request of Melchior Sessa for students of the subject. Its pictures are small, plain woodcut diagrams of the celestial axis, the horizon and meridian, a dial-like circle with labelled quadrants, and a graduated quadrant with a plumb line, drawn in a clear schematic style that a designer could borrow for minimal technical line work and labelled geometric figures.
