Grondige onderrichtinge in de optica, ofte, Perspective konste
A Dutch treatise on perspective by Hendrik Hondius, published in Amsterdam in 1647 by Frederick de Wit, aimed at students learning the optics of drawing. The plates are geometric construction diagrams: vaulted and arched interiors built from converging orthogonals, horizon lines and vanishing points, plus a page of townhouses reduced to boxes with projection rays. A designer could take from them the underlying scaffolding of one-point perspective and how architectural forms are reduced to lines before rendering.
