“The eastern arm, or presbytery, takes its history from the tower. Here, as in the nave, the original triforium windows are blocked up, and a range of Perpendicular work superimposed on the old. Above and beyond this, supported between each bay by flying-buttresses, comes the transitional Decorated to Perpendicular clerestory, higher than the original Norman clerestory remaining to the nave. At the base of each flying-buttress are figures of saints. The roof and Norman clerestory were damaged by the falling tower in 1361, but were rebuilt by Bishop Percy, 1355-69. This work is transitional Decorated to Perpendicular. The presbytery was then re-roofed with a framed timber construction, which was consumed by the falling of the burning spire, struck by lightning in 1463. The present stone vault was added in its place by Bishop Goldwell, 1472-99. This necessitated the addition as well of flying-buttresses to take the thrust of the vault. “The battlementing to the presbytery also was added at the same time as the flying-buttresses. “It will also be noted that here, as in the nave, an addition was made in the way of a range of later ‘Perpendicular’ windows superimposed over the original Norman triforium, which was blocked up.”--(C. H. B. Q.) The south transept projects under the central tower. Next follows the =Chapel of St. Mary the Less= (Fourteenth Century) projecting southward, then the circular =Chapel of St. Luke= (Norman), very peculiar in form, with two rows of arcading. The north side is well viewed from the =Bishop’s Gardens=. It differs little from the south side, except in the fact that it has been less restored. The chapel corresponding with the Chapel of St. Luke is the =Jesus Chapel=, and is also circular. Here we find Perpendicular windows inserted in the Norman work. “The nave on the south side can be seen well either from the upper or lower Close, and can be better examined in detail from the interior of the cloisters. Its elevation consists of fourteen bays divided by flat Norman buttresses. In height it is composed of what, at first sight, appears a bewildering confusion of arches, arcades and windows. Over the aisle windows, hidden by the north walk of cloisters, comes a Norman wall arcading; and over this the Norman triforium windows blocked up, and again, above the later Perpendicular triforium, superimposed on the old, and finished with a battlemented parapet. Behind this come the triforium roof, and then beyond the original Norman clerestory, each bay with a triple arch formation, the centre arch pierced for a window. And then above all, the lead roof over the nave vault.
