La perspectiue d'Euclide
A 1662 French edition of Euclid's optics, Latin-to-French translated by Roland Fréart de Chambray and printed at Le Mans by Jacques Ysambart for readers of perspective and optics. The pictures are plain geometric diagrams of circles, chords, tangents and dotted sight lines labelled with capital letters, drawn in fine black line on uncoloured paper. A designer could borrow their clean construction logic for minimal line diagrams, grids and technical schematics.
