Flemish art was not confined to the boundaries of modern Flanders and several leading artists came from or worked in areas in which langues d'oïl were spoken, from the region of modern Wallonia, e.g. Robert Campin, Rogier van der Weyden (Rogier de la Pasture) and Jacques Daret. Joachim Patinir Henri Blès are generally called mosan painters. Lambert Lombard (Liège, 1505 – 1566) was a Renaissance painter, architect and theorist for the Prince-Bishopric of Liège. Gérard de Lairesse, Bertholet Flemalle were also important painters in the Prince-Bishopric of Liège.
