L' Art De Dessiner
L'Art de Dessiner is a 1788 French drawing manual by Jehan Cousin, held by Heidelberg University Library, written to teach students how to draw the human figure. Its plates are tightly ruled woodcut-style diagrams of heads, faces and eyes, with grid lines, numbered proportions and turned-head views that show how features sit on the skull and how the eye is built up in stages.
