Dictionarium polygraphicum, or, The whole body of arts regularly digested ... : illustrated with fifty-six copper plates
An English encyclopaedia of the arts and trades compiled by mathematics teacher John Barrow and printed in London in 1758 for craftsmen, painters and students, with fifty-six copper plates engraved by W. H. Toms after John Devoto. The plates are perspective demonstrations: lettered points, dotted projection rays, horizon lines and hatched planes and solids receding to vanishing points.
