Traité Élémentaire De La Peinture: Avec 58 figures d'aprés les dessins originaux de le Poussin, dont 34 en taille-douce
A 1803 French treatise on painting, compiled from Leonardo da Vinci's writings and illustrated with copper-engraved diagrams after drawings attributed to Nicolas Poussin, for art students and painters. The pictures are geometric and optical diagrams: lettered rectangles, circles, and sun-ray and light-path sketches, with plain linework that suits designers wanting technical schematic motifs.
