We now enter the Cathedral. Though the nave is less lofty than many, it is most beautiful, and the richness of the architectural details abundantly atones for the lack of height, which is 70 feet. The roof springs from slender vaulting shafts and is studded with beautifully-carved bosses, representing foliage, animals, strange figures and heraldic shields. The murder of Thomas à Becket occurs in one of these bosses. Clustered pillars of Purbeck marble support the roof and separate the nave from the aisles. Notice the sculptured corbels between the arches, which are peculiar, and the exquisite carving of the leaves and figures. In the triforium on the north side is the _Minstrels' Gallery_, the most perfect in England, where the musicians played on high festivals, or on the occasion of some Royal visitor. The figures are represented as playing on various instruments--cittern, bagpipes, flageolet, violin, harp, trumpet, organ, guitar, some unknown wind instrument, tambour and cymbals. The heads of Edward III. and his queen, Philippa, support two niches. This gallery is a very beautiful example of mediæval art. Instead of the usual triforium we have a blind arcade, the height of which is much less than in most cathedrals, but above this there is a very lofty clerestory. The windows of the nave are Decorated, and have a great variety of most beautiful and elaborate tracery. They are arranged in pairs, one window corresponding to its opposite. The glass of the west window, erected in 1766, is a great eyesore, and spoils the beauty of the stone tracery. [Illustration Detail of Minstrels' Gallery] We have abundant evidence that this noble nave was constructed almost entirely in Norman times, and subsequently transformed into the Decorated style, just as Winchester was changed from Norman to Perpendicular work. Disturbances of masonry in both north and south walls indicate the position of Norman pilasters, and outside flat buttresses of Norman type are observed which correspond to the position of these. We gather that the nave was finished in Norman times by Bishop Marshall, and that Stapledon (1308-1326) began the transformation, which was carried on and completed by Grandisson (1327-1369). Nor must the work of our modern men be disregarded. The nave was in a very dilapidated state. The Purbeck marble columns were fallen into decay, and hideous high pews disfigured the view. Sir Gilbert Scott in recent times most judiciously restored the Cathedral, and made it again one of the finest in the land.
