The presbytery was damaged on two occasions by the fall of the tower, and these accidents obliged subsequent repairs and alterations, which were constructed in the style then in use. Hence we have blended with the old Norman work the Decorated clerestory of Bishop Percy (1355-1369), and the Perpendicular roof of Bishop Goldwell, erected a century later. The lower arches were altered by the same bishop into the Perpendicular style, and his name is preserved in the canting rebus--gold and a well. The old Norman triforium remains. The vaulting of the roof is curious. Between each pair of clerestory windows is a niche, and from the heads of these spring the ribs, which form a beautiful example of lierne vaulting. The eastern termination is the original Norman apse, built by Bishop Herbert. The old bishop's throne is particularly interesting, chiefly from its position in the centre of the apse, with the presbyters' seats on each side. This idea was probably derived from Rome, where this position was not uncommon, though unusual in this country. The bishop's throne at Torcelli is a well-known example of this use. The present altar is modern, and also the present floor, designed by Sir Arthur Blomfield. [Illustration Ancient Bishop's Throne] The following are the principal _Monuments_:-- A slab marks the resting place of Bishop Herbert, the founder; Goldwell's Chantry and tomb; Bishop Wakering's tomb (d. 1425); Bishop Overall (d. 1619); Sir W. Boleyn (d. 1505). The _North Transept_, built by Herbert, has good Norman arcading, and a vault erected by Nykke. The clerestory resembles the nave. There was at the east an apsidal chapel dedicated to St. Anne, but it is now closed and used for baser purposes. A processional path runs round the presbytery. On the north side is a curious bridge, which was connected with the Reliquary Chapel, now destroyed, situated on the exterior of the church. This bridge was an ante-chapel to that in which the relics were stored, and is adorned with mural paintings. Probably relics were exhibited here for the worship of the pilgrims, who went in procession along the path below. [Illustration Bridge North Aisle of Presbytery.]
