the aisles of later "Decorated" traceried windows in place of the original Norman ones, and of the superimposition, before referred to, at triforium level of a whole range of "Perpendicular" windows over the old Norman work, which were blocked up at this period. The pristine aspect, then, of this elevation of the nave would have shown a sloping roof over the aisles where now the later addition occurs. The battlementing, too, over the clerestory to the nave is later work, to correspond with battlementing over the triforium windows. It will be noticed that the two bays next the transept in the triforium are higher than the others, in order to throw additional light into the choir. Also on this same south side, in the seventh and eighth bays from the west end, two very late windows occur, inserted in the Norman arcading under the original triforium windows; these were inserted by Bishop Nykke to light the chapel he built in two bays of the south aisle of the nave. The curious raking of the lead rolls to the nave roof is noticeable; the mediaeval builders did this with a view of counteracting the "crawl" of the lead. Lead, under the variations of temperature of the atmosphere, expands and contracts considerably; and from its own weight, and the steepness of the roofs, the contraction takes place in a downward direction, and starts the joints, letting in the weather. This raking of the vertical rolls was a device whereby the old builders in some measure got over their difficulty by inducing a fixed expansion and contraction. [Illustration: The Clerestory and Triforium of Choir (South Side).] #The South Transept# projects boldly forward from under the tower; without aisles, its ridge and parapet correspond in height to those of the nave; this narrowness, with the tower and spire showing over behind, gives it an appearance of height, as approached from the lower close. This effect of height is emphasised by the partition of the design in its w -------------- next part -------------- $B%F%-%9%H7A<00J30$NE:IU%U%!%$%k$rJ]4I$7$^$7$?(B... $B%U%!%$%kL>(B: gauged.jpg $B7?(B: application/octet-stream $B%5%$%:(B: 11208 $B%P%$%H(B $B @ bL@(B: $BL5$7(B Download
