Das Bild Von Atma, Oder Grundlinien Der Zeichenkunst: Mit 12 Steintafeln
Casper H. Tappe's 1824 German treatise on drawing, Das Bild Von Atma, was published with twelve lithographed plates, and these scanned pages from Heidelberg University Library show its geometric construction studies. The plates show abstract scroll, volute and leaf forms built from guide lines, along with a diagram of a lyre-shaped ornament and a perspective grid. A designer could draw on these as a vocabulary of hand-drawn curves and ornamental outlines.
