It seems likely that the logical sequence of seals on the right hand side of the Plan was carefully considered by Blomefield, for the next example also shows his guiding expertise. This is the personal seal of Sir John Clifton of Buckenham (Fig. 13.21), who was appointed as governor of the Norwich during the forfeiture of its liberties between 1443 and 1447 following Gladman’s Revolt, when the validity of the seals made by Couper was suspended. By including Clifton’s seal in this context, Blomefield was able knowingly to refer to an episode in the city’s history and to the career of a notable local benefactor and ‘peacemaker’ who, inter alia, helped the priory of Wymondham gain independent abbey status and contributed to building its new nave clerestory and roof and founded its great west tower.⁴⁰
