A set of engraved plates on the weaver (Tisserand) from Diderot and d'Alembert's Encyclopédie, prepared as Part III of a series of weaving plates. The plates show a French plain-cloth (linen) loom in perspective, plan, front and side elevation, with numbered figures of the frame, beams, heddles, reed, treadles, shuttles, temples and joints. The pages carry only plate titles and figure numbers, with no explanatory text.
