The _South Transept_ is the earliest part of the present Cathedral (1230-1241). The finest view is obtained on entering by the south door. The extraordinary magnitude of the transepts, the five lancets with their old glass, and the beauty of the Early English architecture, are most striking. The triforium is not dwarfed as in the nave, but assumes large proportions, whereas the clerestory is small. The former consists of semi-circular moulded arches, with dog-tooth ornament, each enclosing two pointed arches, and sub-divided into two similar arches. Five pointed arches in each bay constitute the clerestory, with sculptured heads. Clustered shafts of stone and Purbeck marble form the piers. The vaulting is of wood of the fifteenth century, and the bosses are curious. A mermaid and merman, a monk and a nun, look down upon us; an arcade of pointed arches lines the walls. Chantry chapels were formerly in the east aisle. On the south was Ludham's Chantry, archbishop (1258-1265). It contains the large modern monument of Dean Duncombe. Next we see the Chapel of St. Michael with the tomb of its founder, Archbishop Grey (1216-1255), the builder of this transept, and near it the monument of Archbishop Sewal de Bovill (1256-1258). The _North Transept_ resembles the south, but differs in details. Especially noticeable is the profusion of dog-tooth ornament, the magnificent lancet windows, called the "Five Sisters," with the five smaller ones over it. These are the largest ancient lancets in England.[16] Curious grotesques are seen in the triforium moulding. The monuments here are:--(1) a brass to the memory of soldiers slain in India; (2) Archbishop Harcourt's tomb (1808-1843); (3) a skeleton memorial of Thomas Huxby, treasurer (1418-1424); (4) Archbishop Greenfield's tomb (d. 1315), which lies before the place where the altar of St. Nicholas stood; (5) effigy of Dr. Beckwith (d. 1847). In 1829 a disastrous fire occurred in the Cathedral, caused by a lunatic incendiary named Martin. He hid himself on the night of the fire behind the tomb of Archbishop Greenfield. There is a curious doorway leading to the vestibule of the chapter-house of Decorated style. Entering the _Vestibule_ we notice the exact place where the Early English builders finished their work, and the Decorated style begins. The difference between the styles in the chapter-house and vestibule shows that the former was erected first. It has a wall arcade, and above are windows of curious tracery, filled with beautiful old glass. The shafts of the arcade support trefoiled arches, with a cinquefoil ornamented with a sculptured boss. Each boss and capital is beautifully carved with foliage, amidst which the heads of men and dragons appear. The glass is Early Decorated, and contains representations of Royal personages.
