Le nuoue teoriche de i pianeti
A 1566 Venetian astronomy treatise on planetary theory, the Italian edition of Georg von Peurbach's work with additions by Peter Apian, printed by the Sessa firm for scholars and students of the heavens. Its pictures are plain line diagrams of concentric circles, epicycles and eccentrics with lettered points, set in the text block, so a designer might borrow their geometric clarity and orbit-like rings for schematic or mechanical layouts.
