Die durch Theorie erfundene Practic, oder Gründlich-verfasste Reguln, derer man sich als einer Anleitung zu berühmter Künstlere Zeichen-Wercken bestens bedienen kan
An 18th-century German drawing manual edited by the Preißler family and published in 1763, issued from Nuremberg for students learning figure drawing from established artists' works. The plates are etched outline studies of seated and reclining nude male figures set in panels with faint landscape and tree backgrounds, with construction lines and grid guides visible; a designer could take from them the squared-off method of building poses and the economical contour line.
