La prospettiva pratica : delineata in tavole a norma della seconda regola
A practical perspective manual issued in Bologna in 1744 by Lelio dalla Volpe, presenting Vignola's second rule in engraved plates drawn by Gio. Lodovico Quadri for architects, painters and students of drawing. The plates are line-only geometric constructions: polygons inscribed in grids, cubes and cylinders projected from vanishing points, dotted projection rays, lettered reference points, and stacked column bases built from circles.
