Applied perspective, for architects and painters
A technical manual on perspective drawing by American architect William Pitt Preble Longfellow, published in Boston and New York by Houghton, Mifflin in 1901 for architects, painters, and drafting students. The plates are line diagrams in fine engraved strokes: horizon lines, vanishing points, station points, cones of projection, and lettered construction points, often several numbered figures crowded on one sheet, useful as geometric line art, grid backgrounds, or diagram motifs.
