Petri Apiani Cosmographia,
Petri Apiani Cosmographia is a 1539 cosmography textbook by Peter Apian, with additions by Gemma Frisius, printed in Antwerp for students and navigators learning the geography of the heavens and earth. Its woodcuts show astronomical diagrams, a globe-like sphere with a figure observing the sky, a circular emblem of the earth, and a shadow-measuring scene with a sundial-like instrument; a designer might borrow their crisp line work, radiating ray diagrams, and diagrammatic compass-and-circle layouts.
