Disqvisitiones mathematicae, de controversiis et novitatibvs astronomicis ;
A 1614 Latin astronomy treatise by Christoph Scheiner, printed at Ingolstadt, Bavaria, for scholars debating astronomical questions. The four pictures are letterpassed geometric diagrams, a circle-and-arc construction, a dense stippled ring above a printed line, and a grotesque mask ornament, all in plain black woodcut-style print on laid paper. A designer could take the crisp labelled diagrams as schematic line work and the carved mask cartouche as a decorative header or ornament.
