§ 72. The aim of restorers and rebuilders from the middle of the fourteenth century onwards was to convert the church into a rectangle with aisles. As we have seen, the chancel was constantly, in late Gothic churches, an aisleless projection from the main fabric; but, where it was aisled, the old haphazard methods were often abandoned, and the aisles were made of approximately equal size. The old distinction between nave and chancel, marked by the chancel arch, and the arches between chapels and aisles, begin to vanish. Where the chancel arch was kept, as at Long Sutton in Lincolnshire, new chancel chapels were prolonged westward on each side of the nave, in place of the old nave aisles. Fairford church in Gloucestershire was rebuilt towards the end of the fifteenth century, to contain the splendid stained glass which had just been acquired for it. A central tower was built on strong piers, as a concession to the old plan; but the aisles of the nave were continued on either side of the tower and along the sides of the chancel till within a bay of the east end. But, in a great many churches, not merely the aisles, but the nave and chancel also became continuous, without a structural division. This feature, common in East Anglia and the south-west of England, was the result of the importance of carved and painted wood-work in late Gothic churches. The rood screen, stretching across nave and aisles, appeared to full advantage, when unbroken by the chancel arch. The splendid timber roofs of nave and aisles gained in effect, if they formed, as at Southwold, or in the churches of Norwich, an unbroken covering to the church from end to end. In Norfolk and Suffolk, where the work of rebuilding began in the fourteenth century, as at Cawston, Worstead, or Tunstead, the chancel arch was often kept. At Worstead and other Norfolk churches the method pursued by the builders was precisely opposite to that which we have seen employed by Gloucestershire masons at Cirencester and other places, and may see in most of the fifteenth century churches of Somerset. The arcades were rebuilt first, and the aisles followed. Many of these churches were doubtless enlarged from much smaller buildings. The south aisle at Ingham was probably the nave of the earlier church, to which the present nave, north aisle, chancel, and west tower, were added. The aisles in most cases continued at a uniform width eastward as chancel chapels. The north aisle at Worstead was continued by a two-storied sacristy to the level of the east wall of the chancel. The south aisle stops at a bay short of the east wall, leaving the end of the chancel projecting as an altar space. Whether the chancel arch was retained or not, the projection of this aisleless eastern bay became a very general feature of the larger churches of East Anglia, and, in churches like Trunch, Southwold, and Clare, its tall side windows flood the space with light The most striking example of this plan is at Long Melford in Suffolk, where there is no chancel arch, and the actual chancel projects beyond the aisles. Here, however, it is flanked on the north by the Clopton chapel, and on the south by the vestry, which forms a covered way to the detached lady chapel further east. The Long Melford plan, with a projecting altar space, and without a chancel arch, is nearly universal in Cornwall, and is common in south Devon, where, as at Totnes, the aisles of the chancel are usually little more than comparatively short chapels, and sometimes, as at West Alvington, near Kingsbridge, extend only a bay beyond the screen. Its great advantages, apart from the display of wood-work which it permits, are the gain of internal space permitted by the reduction of the solid portions of the building to a minimum, the additional light admitted by the same means, and the long uninterrupted clerestory which forms a wall of glass, with thin stone divisions, on each side of the upper part of the church.
