Précis des leçons d'architecture données à l'École polytechnique

The 77 engraved plates set plans, elevations and sections on ruled grids, reducing walls, piers and colonnades to black blocks and dots that combine into porticoes, basilicas, theatres and palace layouts; useful as modular pattern, diagram, and grid-based ornament.
