We enter by the north porch. The _Nave_ covers the same ground as the original Norman Cathedral, and some remains of the old building are left. At the west end the door entering into the north aisle, at the north-east angle of the north aisle, and the great Norman shafts running up the centre of the second piers from the west, are pure Norman. The two _Western Bays_ are Transition Norman, and are an interesting study. We see here almost the earliest advance of Gothic art and the earliest traces of the Early English feeling which manifested itself for the first time in its developed form in the choir of Lincoln. It will be observed that the arches are pointed, but the capitals are Late Norman. The triforium is peculiar, and has a series of pointed arches over three round-headed openings, the centre one being much higher than the rest, and the ornaments are the zigzag, lozenge and curious knots of carved leafage. The clerestory consists of groups of three windows under round arches, the tracery at the back being Perpendicular insertions. The date of this portion is about 1160. The vault was fashioned by Bishop Wakefield (1375-1394). There are seven remaining bays. Those on the south are later than those on the north, and the earlier work is the richer and more beautiful. On the north the five eastern bays and the pier arches of the other two are Decorated (1317-1327), while the rest of these two bays and all the south side are Early Perpendicular. The great west window is modern, erected in 1865 in Early Decorated style. Sculptured figures of characters from the Old Testament appear in the tympana of the triforium. The _South Aisle_ has two west bays of Transition Norman work like the nave, quadripartite vaulting, Late Decorated windows, high in the wall on account of the cloister on the other side, and two doorways called the monks' and the prior's. The wall is original Norman. Here is a large modern font. The _North Aisle_ has also the two west bays of Transition Norman. The vaulting is Decorated, the work of Bishop Cobham (1317-1321), and the rest of the aisle belongs to the same period. The _Jesus Chapel_ opens from this aisle, separated by a modern screen in Perpendicular style. This chapel has been recently restored by the Hon. Percy Alsop, and the scheme of decoration is very elaborate and beautiful. The _Pulpit_ is a very handsome and elaborate structure made of marble and alabaster, with some excellent carving.
