The choir transepts are now reached. That on the north side, with its inverted arch, contains, among others, the tomb of Bishop Jewel (died 1571) who despoiled the nave windows of their colour. He was the first post-Reformation Bishop of Salisbury. Just within the entrance is the interesting brass of Bishop Wyville, builder of the spire. It records the recovery, through trial by combat, of Sherborne Castle for the church. The slab of the Saint-Bishop Osmund's tomb (1099), one of those wantonly interfered with by Wyatt and a relic of the Cathedral of Old Sarum, has been brought from the nave to its present position near the end of the north choir aisle and not far from its former magnificent shrine. The chief beauty of the Lady Chapel consists in the slender shafts of Purbeck marble that support the roof. The tryptych altarpiece is modern, also the east window in memory of Dean Lear. Opinion will be divided as to the merit of the roof decoration, but time will lend its aid in the colour scheme. In this connexion may be mentioned the means taken here as elsewhere to remove the curious "bloom," that comes in the course of a generation or two, upon the Purbeck marble columns. They are oiled! Attention is again called to the sketch plan for the tombs hereabouts, and in the south choir aisle, where especial notice should be taken of the canopied tomb of Bishop Giles de Bridport. The muniment room, reached from the south-east transept, contains a contemporary copy of Magna Carta, besides many other interesting manuscripts and treasures. The Cathedral Library is above the cloisters. Its collection of manuscripts is magnificent, some dating as far back as the ninth century. The windows in the cloisters are of very fine design, and some fragments of old glass in the upper portions show that they were once glazed. The original shafts of Purbeck marble had so decayed by the middle of the last century that it was decided to replace them with a more durable stone. Very beautiful is the octagonal chapter house, entered from the east walk. The bas-reliefs below the windows and above the seats for the clergy are of great interest. The sculptures in the arch of the doorway should also be particularly noticed. From a door in the cloisters there is a charming view of the Bishop's Palace and the beautiful gardens that surround it.
