Perspective practical, or, A plain and easie method of true and lively representing all things to the eye at a distance, by the exact rules of art ...
A 1698 London perspective manual by Jean Dubreuil, issued by publisher Robert Pricke, offering plain practical rules for drawing objects convincingly at a distance to anyone learning the art. The pictures are precise line diagrams of receding floor grids, horizon lines, vanishing points and projected plans, showing how orthogonals converge and how shapes are constructed in space, a useful reference for designers working on grids, depth and geometric layout.
