The Lady Chapel and the ambulatory or vestibule were evidently twice prepared for vaulting before Bishop Vaughan actually completed the scheme, but during the Civil War it was denuded of lead, which eventuated in its collapse about 1775 and in the erection of the extraordinary modern buttresses which prop up the inner walls of the chapel and its aisles. This brief general description may help the visitor to realise the many changes which produced these peculiar eastern adjuncts, and we will now discuss each more in detail. =Bishop Vaughan’s, or The Trinity, Chapel.=--This chapel is a peculiarly subtle example of Perpendicular, and retains both its internal and external roofs. Freeman, who does not usually pay high tribute to any phase of Perpendicular, says,[61] “Bishop Vaughan’s Chapel is an extremely fine specimen of late Perpendicular, and that of the best kind, and is the more conspicuous, as being the only portion of the cathedral of any merit or importance belonging to that style. It exhibits the same chasteness of design and delicacy of execution which distinguishes King’s College Chapel, opposed alike to the meagreness of Bath Abbey and the corrupt form and overdone ornament of Henry the Seventh’s Chapel. The arches, one on each side, which divide the chapel from the aisles, command admiration for the justness of their proportions and the purity of their detail, being well moulded, and having shafts with good capitals and bases; the stone screens also with which they are fitted up increase the effect of elegant richness. It is much to be regretted that they should remain exposed to the effect of the weather, even comparatively sheltered as they are by the main body of the cathedral.
