Zeichenbuch für Künstler und Liebhaber der freyen Handzeichnung, insbesondere als ein nöthiger Theil der Erziehung höherer Bestimmung behandelt
Zeichenbuch für Künstler und Liebhaber der freyen Handzeichnung is a German drawing manual of 1803, edited by Johann Quirin Jahn and Johann Heinrich Balzer, held by Heidelberg University Library and aimed at artists, amateurs, and students in higher education. Its plates show engraved studies of isolated legs, feet, torsos and hips in pencil-like hatching, with measurement grids and Roman plate numbers. A designer could take from them a clear method for drawing anatomy in line, with linear contour and cross-hatched shadow.
