Article on a mise en cartes (working pattern for the weaver) by the Lyons silk designer Philippe de Lasalle, recently acquired by the Metropolitan Museum of Art with a group of eighteenth-century brocades bought in Lyons. It sketches Lasalle's life (1723 to 1804), the rococo and naturalistic floral styles of Lyons silks, and Jean Revel's 'point rentré' technique for rendering half-tones. It quotes a tribute by M. Cox of the Musée Historique des Tissus, Lyons, on Lasalle's style and his ruin in the Revolution. Illustrated with portraits, paintings showing brocade gowns, and two reproductions of silks designed by Lasalle.
