Della fabrica & vso di vn novo stromento, fatto in quattro maniere per fare gli horologi solari ad ogni latitvdine : con tutte le sorti di hore, che si vsano, ilquale si può vsare per horologio ancora : nouo trattato diuiso in due parti
A 1590 Venetian treatise by Giovanni Paolo Gallucci, printed in Venice by Gratioso Perchacino, explaining the construction and use of a novel instrument for making sundials at any latitude and for telling hours. The pictures are plain woodcut diagrams of geometric dials, scaled arcs with numbered degrees, and a portable hand-held instrument with a stand, drawn in clean black line with dense hatching, useful to a designer for technical line work, scale markings, and mechanical instrument forms.
