La pratica della perspettiva is a 1568 Venetian treatise on perspective by Daniel Barbaro, published by the Borgominieri brothers for painters, sculptors and architects. Its pictures are geometric diagrams of squares, circles and polyhedra drawn in fine black line with lettered points, the kind of construction a designer could reuse for grid layouts, proportional systems and perspective setups.
