Andreae Alberti zwey Bücher, das erste von der ohne und durch die Arithmetica gefundenen Perspectiva, das andere von dem darzu gehörigen Schatten
A 1671 German treatise on linear perspective and shadow by Andreas Albrecht, printed by Fürst and issued for draughtsmen and students of perspective. Its folding plates show geometric construction diagrams of vanishing points and orthogonals beside finished interior views of rooms with shadowed furniture and objects, which a designer could use as a reference for one-point perspective and cast-shadow study.
