De gli horologi solari
A 1638 Venetian treatise on sundials by Mutio Oddi, published by Ginammi, whose pages are geometric diagrams of circles, chords and construction lines printed in Italian for mathematicians and instrument makers. The four plates show lettered circles, intersecting lines and angled rays drawn with plain black linework on cream paper, a clear reference for anyone designing dials, radial grids or compass-like geometry.
