A 1518 Venetian edition of Sacrobosco's Sphere, a Latin astronomy textbook with commentaries by Cecco d'Ascoli and Francesco Capuano, printed for scholars and university students of cosmography. Its pictures are plain line diagrams of circles, cones, and sectors with lettered points, showing how the heavens and the earth's shadow were geometrically modelled, which a designer might use as clean schematic geometry for abstract line work.
