Crossing the north aisle to the presbytery, at the fourth bay eastward past the tower, marked F on plan, there occurs a curious bridge chapel spanning the aisle, access thereto being gained by a newel staircase on the north side. In our notes on the Presbytery, we have referred to the uses assigned to this structure and its connection with the Easter sepulchre. It formed the ante-chapel to the reliquary chapel projecting northward from the outer wall of the cathedral; it probably was built as a bridge so that relics and symbols might be exhibited thereon to processions passing along underneath. It is decorated in character, and the vault is constructed of chalk. The chapel above is decorated with frescoes, the subjects of which are as follow:--In the western quarter of the four-part vault, The Blessed Virgin between SS. Margaret and Catherine; in the eastern, SS. Andrew, Peter, and Paul; in the northern, SS. Martin, Nicholas, Richard; in the southern, SS. Edmund, Lawrence, and a bishop; a figure of Christ occurs centrally. Copies of these frescoes have been made in facsimile, and hang in the aisle and consistory court. Passing through the small door in the north wall of the north aisle before mentioned to the outside, the lines of the reliquary chapel can be plainly seen, and also of another to the west; the position of both these chapels is shown by dotted lines on the plan. [Illustration: Detail of the Clerestory, North Transept.] A coped coffin lid of Purbeck marble, now in the aisle of presbytery, should be noticed; an inscribed brass once occupied the bevelled edge. [Illustration: The South Aisle of Presbytery, looking East.] #The Chapels.#--In the Norman cathedral, grouped round the east end of the presbytery, was a trefoil of chapels; the one on the north, the Jesus Chapel, yet remains, and as well its fellow on the south. The Lady Chapel, or easternmost of the three (shown on plan by dotted lines) was succeeded by an Early English building, which, in its turn, was destroyed; the entrance arches, of beautiful proportion, alone remaining. [Illustration: Norman Work in the Lantern of Tower.] #The Jesus Chapel# formerly belonged to the bishop. On plan its shape is that of segments of circles joined, the altar placed in the smaller part. A simple wall arcade runs round the lower half, the whole being covered by a plain quadri-partite vault. The windows are insertions of Perpendicular work, varied in character from the Norman work of the chapel itself. The mural colouring is a restoration; it may be something like the original, but the general effect is somewhat garish. [Illustration: The Ante-Reliquary Bridge Chapel.] The altar consists of a slab of grey Barnack-stone, with Purbeck inlaid, the whole being supported on shafts. The tomb of Sir Thomas Wyndham, now in the north of nave, at one time stood here, as also the pelican lectern now in the choir.
