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 Johann Daniel and Johann Justin Preißler, published in 1762 and drawn from the Heidelberg University Library, intended as a practical guide for students learning to draw from established artists' models. The plates are engraved studies of the human figure, with torsos seen from front, back and three-quarter views, legs, and reclining poses, each set out on a light ruled grid. A designer could take from them the clear, systematic method of anatomical figure construction, with its fine contour hatching and faint guide lines.
