A 1574 Latin treatise on gnomons and sundials by Venetian philosopher Giovanni Battista Benedetti, published at Turin for scholars and the general public. Its pages are dense with geometric diagrams of circles, chords, and sun-path construction lines, drawn with careful lettered points. A designer might take its clean radial layouts and labelled circle diagrams as models for compass-based, astronomical, or instructional graphics.
