Nuouo, e facil modo di fare horologi solari, orizontali, e verticali, a tutte l' eleuationi di polo : come anche portatili a sole, luna, e stelle per diuerse eleuationi di polo : in varie figure
Nuouo, e facil modo di fare horologi solari is a 1688 Italian treatise on sundial construction, written by Girolamo Cantone and printed in Turin by the heirs of Colonna for Giovanni Battista Vernoni. Its pictures are geometric line diagrams with lettered points, circles, and radiating rays, showing how to lay out hour lines; a designer might take from them the clean construction logic of radial grids and arcs as a basis for dial or radiating pattern work.
