La pratica di prospettiva
La pratica di prospettiva is a 1625 Venetian treatise on perspective by Lorenzo Sirigatti, published by Pietro Miloco for practising draughtsmen and architects. Its plates show geometric solids drawn in perspective, with spheres built from pyramids and polyhedral shells rendered in fine engraved hatching. A designer might borrow the faceted, spiked sphere forms and the cross-hatched shading as a model for dimensional patterns and geometric ornament.
