Passing on to the east we notice the beautiful lofty choir. The main part of the walls are Norman, and we notice the unusual polygonal radiating chapels, which are part of the original Norman plan. The windows are Decorated and Perpendicular, inserted in Norman openings. The great east window is the largest and finest in England. The _Lady Chapel_ was originally Early English work, built in 1225, but it was rebuilt in 1457-1499, during the rule of Abbots Hanley and Farley. It has four bays, each bay being filled with a lofty Perpendicular window. There is a passage beneath the chapel, which was necessary in order to reach the northern side. The chapel is one of the most beautiful in England. The central _Tower_ is remarkable for its grace and grandeur. The present one is the work of Abbot Seabrooke (1450-1457), and belongs to the Perpendicular period. The bells are ancient, and happily were saved, when the monastery was dissolved, from the greedy hands of the commissioners of Henry VIII. The monastic buildings are on the north side, which we shall examine later. There is a fine view of the Cathedral from the north-west. On the north-west is the Deanery, formerly the prior's lodging, a very interesting house; and between it and the north aisle is a passage, the old Norman slype communicating between the cloisters and the close. THE INTERIOR [Illustration NAVE PILLARS FROM THE WEST] Entering by the south porch we note its Norman character. The old Norman wooden roof has been replaced by a stone vault, and Decorated windows of the time of the second Edward have been inserted, but otherwise there has been little change. The west end, with two bays of the nave, is Abbot Morwent's work (1420-1437). He destroyed two western towers or turrets, which were built in 1222-1243 in place of two similar Norman structures. The height of the Norman piers is unusual, leaving a small space for the triforium and clerestory. The zigzag and double cable moulding appear on the main arches. Abbot Serlo was the builder of the original nave. The stone vault was erected by the monks in the thirteenth century (1242), when the clerestory was altered in the Early English style by Abbot Foliot (1228-1243). Morwent inserted Perpendicular tracery in these windows. The remains of coloured decoration were discovered during the restoration. We have mentioned the numerous fires which wrought havoc here. Traces of the fire may still be seen in the reddened surface of the piers. The contrast between the Norman piers and the Perpendicular piers at the west end is noticeable, also the disappearance of the triforium in the last bay and the lierne vault. The west window contains some modern glass inserted in memory of Bishop Monk (1856). There is a curious series of grotesque heads on the arches of the nave showing the mummeries of gleemen. The story of the _North Aisle_ is similar to that of the nave. We have the same Norman work and the
