Prospectus de l'Etablissement des Piranesi : développement et détail des articles sous le no. 1163 du livre de l'Exposition publique des produits de l'industrie française, au Palais du Louvre
A prospectus issued in Paris in 1819 by the Etablissement des Piranesi, a printing firm showing its reproductions at the French national industry exhibition in the Louvre, aimed at potential buyers and exhibition visitors. The four plates are etched views of Roman ruins and churches, with a medallion portrait and a seated figure beside a bust, rendered in fine hatched line that shows how tonal depth can be built from parallel strokes alone.
