Johann Daniel Preißlers, ehemaligen Direktors der Maler- und Zeichen-Akademie zu Nürnberg, Theoretisch-Praktischer Unterricht im Zeichnen
Johann Daniel Preissler's 1807 drawing instruction manual, issued by a former director of the Nuremberg painting and drawing academy, teaches students to copy figures by squaring grids across paired plates. The pictures are stacked engraved studies of nude male figures in landscape settings, each pair showing a pose at two stages of proportion, which a designer could use as a reference for figure construction and gridded layout.
