Die durch Theorie erfundene Practic, oder Gründlich-verfasste Reguln, deren man sich als einer Anleitung zu berühmter Künstlere Zeichen-Wercken bestens bedienen kan
A drawing manual by Johann Daniel Preißler, published in 1789 and held by Heidelberg University Library, meant to teach students to draw by following the rules of famous artists' works. The four engravings show nude male and female figures in classical and devotional poses, drawn with fine hatched lines against plain backgrounds. A designer could take from them a study of the human figure in contrapposto, drapery, and the anatomy of arms and legs in outline engraving.
