Modo di fare horologi portatili a sole, luna, e stelle : sopra colonelle, croci, medaglie, e scatolini, da seruirsene senza l'ago calamitato per diuerse eleuationi di polo
A 1682 Italian treatise on portable sundials, moon and star dials, published in Turin by the heirs of Carlo Gianelli and edited by Giuseppe Vernoni, written by Girolamo Cantone for instrument makers and navigators working at different latitudes. The pictures are small black-and-white woodcut diagrams of graduated quadrants and a rotating paper calendar wheel, plus repeated ornamental woodcut headpieces with masks and scrolls that a designer could borrow for decorative borders or type-led layouts.
