Josse.
Vous êtes orfèvre, Monsieur Josse (You are a jeweller, Mr. Josse). Nothing like leather; great is Diana of the Ephesians; your advice is not disinterested. In Molières comedy of LAmour Médecin, a silversmith, by the name of Josse, being asked the best way of curing a lady pining from love, recommends a handsome present of jewellery. The father replies, You advise me like a jeweller, Mr. Josse.
