Figure 7.3 – Vue Perspective de l'interieur de l'Eglise Paroissiale de S'. Roch de Paris,

This is a typical vue d'optique of a grand interior. We are looking straight into what art historian Erwin Panofsky calls a "space box." The image is a hybrid of conventional perspective and wide-angle perspective – what I term "hybrid projection" – which gives it exaggerated breadth and perspectival depth. Note how the title appears twice, once at the top in reverse. This way it can be read when viewed in a zograscope, whose mirror reverses the view, or in an optical box, where it appears as we see it here.
