A 1534 Nuremberg printing of Peter Apian's edition of Ptolemy, Gherardo da Cremona and Geber's astronomy treatises, issued for scholars and students of mathematical astronomy. Its pages are dense with geometric diagrams of circles, chords, arcs and lettered points, with Latin text set in blocks beside them, so a designer could draw on their clean compass-and-straightedge linework and fine lettering.
