ABC of Gothic architecture
An 1882 London handbook by architect John Henry Parker, part of his ABC series, teaching students and general readers the features of Gothic architecture through plain engraved diagrams. The four plates show tracery-filled windows, a traceried opening set within an arched recess, and clustered vaulting shafts fanning out from their bases. A designer could take from them the repeating geometry of Gothic pointed arches, lancets, and foil-shaped tracery as ready-made structural ornament.
