Arte gnomonica [manuscript]

Colomboni, Angelo Maria, 1608-1672, Burndy Library, donor. DSI · 1700 · 8 pictures

This manuscript treatise on gnomonics, or sundial construction, was written by Angelo Maria Colomboni (1608-1672) and copied out around 1700, with the handwritten text laid out in Italian beside hand-drawn geometric diagrams. The pages show ruled manuscript text with compass-and-ruler constructions of arcs, meridian lines and sun-ray paths, plus a decorated plate with a figure observing a dial. A designer could draw on the precise, lightly inked line work of these sun-path diagrams and the ornamental cartouche framing the dial plate.
