Apologia R.P. Io. Bapt. Ricciolii ... pro argvmento physicomathematico contra systema copernicanvm : adiecto contra illud nouo argumento ex reflexo motu grauium decidentium
A 1669 Venetian Latin treatise by the Jesuit astronomer Giovanni Battista Riccioli, written as a polemic against Copernican cosmology and aimed at scholars and fellow astronomers. Its pictures are geometric diagrams with lettered points, dashed and solid arcs, circles, and straight lines, set in running text on the page, showing the proofs of planetary and falling-body motion. A designer could draw on their precise, hand-engraved line work, the clean lettering, and the way intersecting curves build a structure from simple forms.
