Théroie des machines mues par la force de la vapeur de l'eau
A late eighteenth-century French technical treatise on steam-powered machines, issued in 1784 by the Frères Gay press and held by the Eisenbibliothek Schlatt, aimed at engineers and mechanics. Its folding plates are dense engineering cross-sections and plans of boilers, pipes, chains and furnaces, drawn in crisp black line with grey washes, which a designer could borrow for diagrammatic linework, schematic labelling and industrial texture.
