An illustrated French-language study of the Lyon silk weaver's (canut's) workshop in the 19th century, written for the Conservatoire des Vieux Métiers du Textile. It describes the Lyonnais hand loom part by part (frame, warp-tension 'bascules', beater, regulator), the weaver's tools such as shears, shuttles, and the brocheur, and Jacquard mechanisms, followed by a section on silk velvet weaving (plain, cut and ciselé velvet). It also contains a history of the Lyon silk industry from its origins through the Jacquard era, and a long dictionary of silk-weaving terms that mixes modern definitions with Encyclopédie-style entries. Many photographs of looms and tools from the Atelier du Chelu and technical line drawings illustrate it.
