Set of engraved plates from Diderot and d'Alembert's Encyclopédie illustrating the Marly (Marli) loom, a draw loom used for weaving gauze-like fabric. The plates show perspective views, a lateral elevation and front elevation with a scale bar, and detailed drawings of the individual loom parts, numbered by figure. The cover page credits Philippe Demoule for preparing the set; the only text is the plate captions in French.
