Die durch Theorie erfundene Practic, oder Gründlich-verfasste Reguln, deren man sich als einer Anleitung zu berühmter Künstlere Zeichen-Wercken bestens bedienen kan
Johann Daniel Preißler's 1722 German drawing manual, issued from Nuremberg for art students, teaches proportion and figure construction through paired sketches. The pages show seated and reclining nude male figures drawn over faint construction grids, with the upper and lower panels reworking the same pose. A designer can take from them the method of blocking a figure with guidelines before finishing the contours, and the way a pose is revised across panels.
