Partie graphique des cours d'architecture faits à l'École royale polytechnique depuis sa réorganisation; précédée d'un sommaire des leçons relatives à ce nouveau travail
Jean-Nicolas-Louis Durand's 1821 Paris volume of engraved plates accompanying his architecture lectures at the École royale polytechnique, issued for engineering students learning to compose buildings from standard parts on a grid. The plates are line-engraved plans, sections and elevations in black on cream, built from modular axes, dotted construction grids, hatched piers, colonnades, domes, apses and stair blocks, and yield reusable geometric patterns, repeating column dots and precise architectural linework.
