A view d'optique of Peterskirche (St. Peter's Church) in Vienna. Vues d’optique are hand-colored etchings and engravings intended to be viewed through a convex lens. The devices, known variously as zograscopes, optiques, optical machines and peepshows, were an optical entertainment of the late 18th and early 19th centuries. Vues d’optiques were rendered in high-key color and dramatic linear perspective, which enhanced the illusion of three-dimensionality when viewed through the lens.
