L' architettura pratica : dettata nella scuola e cattedra dell'insigne Accademia di San Luca
L'architettura pratica, a practical building-construction textbook by the Roman architect Giuseppe Valadier, published in 1828 and taught at the Accademia di San Luca for students of architecture. Its engraved plates, drawn in outline with pale wash, show masonry arches, vaults, timber joinery, and lifting and measuring tools, with keyed lettering and figure numbers; a designer could take their clean diagrammatic linework and hand-coloured sectional views as a model for technical illustration.
