The whole incongruous covering of the east end of the choir shown on p. 77 was then removed, and the change effected was most striking. It was evident that long before the introduction of the Grecian screen in 1717, the original arrangement had been disturbed by the insertion of a Perpendicular window, to support which the low circular arch in the centre had been constructed; on either side of this window were now to be seen the mouldings and featherings of the original early decorated lights, on a level with the lateral clerestory range; below these the Norman arcade, based upon a string course of nebule ornaments. "But below," says Dean Merewether, "the beauty of beauties was to be traced,—the thickness of that part of the wall is 8 feet; on either side of the arch, 24 feet in span, were portions of shafts, corresponding with the pair of Norman shafts exposed to view seven years ago. The bases of these (standing on a sort of plinth, which was continued through those already referred to), as well as the capitals, of most curious detail, were perfect, and upon them were visible as far as the level of the window above, the remaining stones which formed the architecture of the exterior arch, from which it was evident that its crown must have risen to the height of 30 feet. By cautious examination of the parts walled up, it was discovered that the capitals were all perfect, and that this exquisite and grand construction, the mutilation and concealment of which it is utterly impossible to account for, was, in fact, made up of five arches, the interior and smallest supported by the two semi-columns already described, and each of the others increasing in span as it approached the front upon square and circular shafts alternately, the faces of each arch being beautifully decorated with the choicest Norman ornaments. Of the four lateral arches, the two first had been not only hidden by the oak panelling of the screen, but were also, like the two others, closed up with lath and plaster, as the central arch; and when these incumbrances and desecrations were taken away, it is impossible to describe adequately the glorious effect produced, rendered more solemn and impressive by the appearance of the ancient monuments of Bishops Reynelm, Mayew, Stanbury, and Benet, whose ashes rest beneath these massive arches, of which, together with the noble triforium above, before the Conquest, Athelstan had probably been the founder, and the former of those just mentioned, the completer and restorer after that era."
