The junction between the earlier and the later presbytery is well seen from here--too well seen, in fact, for it is awkwardly managed. The later choir windows, with their crocketed ogee hood-moulds, are a good feature, and so are the flying buttresses; but the high-pitched roof of the earlier aisle is discontinued at the break in order to give room for these windows and buttresses; and the effect of this sudden termination of an aisle roof half-way along a building is not pleasant. In the earlier part, too, the later windows have been clumsily inserted some distance below the Early English dripstone, as if only the internal effect had been considered. The same may also be said of the window in the south transept gable: the gable, by the way, is a much plainer affair than that of the north transept. Here stood the two CLOISTER LADY CHAPELS, but unfortunately their sites were not marked on the grass after the excavations were finished three years ago. Thus nothing can be seen from here of the earlier chapel, and, of the later, only the doorway and the Perpendicular panelling against the cloister which marks its western end, and the commencement of the walls. A small quatrefoiled hagioscope may be noticed in the library above the cloister; it, no doubt, commanded a view of the high altar of the chapel. The earlier _Capella B.M.V. juxta claustrum_ is often referred to in the chapter documents, and was a favourite centre of devotion. It became a kind of family chapel for the numerous clan of Byttons, after the first bishop of that name was buried there; it was also sometimes used as a chapter-house. The Early English doorway which led to it can still be seen in the cloister wall, on the right of the present doorway; it is partly covered by an I.H.S. of later date, made with the instruments of the Passion. The excavations of 1894, when the foundations were laid bare under Mr Buckle's direction, showed that this chapel consisted originally of a plain oblong building, earlier even than the north porch in date (_i.e._ before 1185), which was afterwards (c. 1275) enlarged by the addition of an aisle on either side. The excavations showed that arches were used at this time to replace the western part of the older walls, and thus to throw the ancient chapel open to its new aisles. The original chapel, then, if it was not actually part of Bishop Gisa's buildings, spared when John de Villula destroyed Gisa's cloister, seems to have been built not long after Gisa's time, and at least on the site of Gisa's chapel. This would account for its orientation, which was in a more northerly direction than that of the cathedral, and probably was the same as that of the pre-Norman church. Excellent plans of the foundations both of this and the later chapel are to be found in the _Somerset Proceedings_ for 1894, where the whole matter is discussed in detail by Canon Church and Mr Edmund Buckle.
