Paradossi per pratticare la prospettiva senza saperla, fiori, per facilitare l'intelligenza, frvtti, per non operare alla cieca : cognitioni necessarie a pittori, scultori, architetti, ed à qualunque si diletta di disegno
Giulio Troili's Paradossi per pratticare la prospettiva senza saperla, printed in Bologna in 1672 for painters, sculptors, architects and amateur draughtsmen learning perspective by rule rather than theory. Woodcut plates show vanishing-point constructions, gridded floors, sightlines and lens diagrams, each set inside a decorative border of flowers and fruit that can be lifted as a frame on its own.
