Les principes du dessein, ou, Methode courte et facile pour aprendre cet art en peu de tems
Les principes du dessein is a 1746 French drawing manual by the Dutch painter Gérard de Lairesse (1640-1711), published in Amsterdam and Leipzig to teach drawing as a short, practical method for students. Its pictures are faint, pale plates on blank facing pages, with one crisp pen-and-ink study of a seated male nude that shows the figure's musculature and drapery, a useful model for a designer studying anatomy and contour.
