Dialogo della descrittione teorica et pratica de gli horologi solari
A 1565 Italian treatise on sundials and astronomical instruments, printed in Ferrara by Valente Panizza and written by Giovanni Battista Vimercato for readers of practical geometry and horology. Its pictures are plain woodcut diagrams of circles, radiating hour lines, quadrants and a ring dial with Roman numerals, drawn in fine black line on cream paper, offering a designer clean geometric schematics with crisp radial structure and dense typographic captions.
