This is a 1647 French treatise on drawing the human figure by Jean Cousin, a painter and geometer, issued for painters, sculptors and architects. Its plates break the head, face, hands and figure into measured parts shown in front, profile and three-quarter views, with marked proportions and grid lines. A designer can take from them a clear method for constructing figures, with curly-haired classical heads and hands shown from several angles as reference for proportion and foreshortening.
