Traicté de perspective
A 1660 treatise on perspective published in Paris by Jollain, written by Jacques Le Bicheur, a geometric instruction book for artists and draughtsmen. The single picture is a dark, grainy print of intersecting lines and a rectangular frame, which suggests how orthogonal lines converge toward a vanishing point; a designer could take from it a sense of rigid structure built from receding diagonals and a heavy textured field.
