Cosmographicus liber Petri Apiani mathematici,
A 1533 Antwerp cosmography by mathematician Peter Apian, with Gemma Frisius's treatise on describing places, printed for scholars and navigators. The pictures are rows of hand-printed circular diagrams of the moon in its phases and eclipses, each labelled with a date, hours and minutes, and month names in Latin; a designer might draw on their tidy grid of dark and pale disks and their classic woodcut texture.
