An 1881 German technical dictionary of building and engineering, the Illustrirtes Bau-Lexikon, compiled by Oskar Mothes and published in Leipzig and Berlin by O. Spamer for architects, engineers and builders. Its pictures are numbered cross-sections and elevations of arches, bridges, furnaces and kilns, drawn in clean black line with scale bars and lettered reference points. A designer might draw on their precise, diagrammatic clarity for vintage technical diagram treatments, measured linework and labelled schematic layouts.
