The west end of the nave has six windows grouped in it above the porch. The two upper ones are small and close up under the gable coping. This latter is simply chamfered and capped with a modern cross. The windows are arched in two orders. The inner order has a plain, straight chamfered moulding; and the outer, a hollow chamfered one. The label-mould and the capitals of the attached shafts in the jambs are a little later in design than the windows themselves. A moulded string-course separates the point of the large west window from those above it; and from the level of this string-course up to the coping of the gable the whole surface of the wall is covered with a diagonal pattern of incised diapers. The West Window is entirely modern, but copied from fourteenth-century examples with some success. It has five divisions between the jambs and mullions. The central one is larger than those on either side. The upper part is filled with geometrical tracery. Below the west window are three other windows grouped together. They are at the triforium level, where they were probably inserted before the middle of the thirteenth century; but they have been restored at various times since then. The #West Porch# is a comparatively simple structure. It rises from the ground with a deep weathered base. At the top of the walls is a plain weathered coping, which overhangs about one inch. The simple, but extremely well designed, buttresses at the north and south angles add much interest to it as a composition artistically and as a study in structure. The small, straight buttresses on the west are only weathered once, and this at the top; but those on the north and south sides are different. There is a broad central buttress weathered twice from the base to its top, and in the angle on either side of it are what appear to be two lower, smaller buttresses, with one weathering slope. The probability is that there was only a small buttress here at first, and that the larger one on either side was added by being built over the shallower, broader, and shorter one. [Illustration: WALL-ARCADE IN THE WEST PORCH. _S.B. Bolas & Co., photo_.] These buttresses have been placed here in order to counteract the thrust of the large, deeply-set covering arch over the entrance to the porch. This arch is of interest, as it has but a slight label; and then the outside angle of the soffit only is moulded, the rest being recessed both at the jambs and in the arch for about two feet, with no mouldings at all. Then comes a delicately moulded arch in two orders, immediately beneath which are the coupled arches which give entrance to the interior, vaulted apartment. These two arches, the central and side shafts on which they rest, as well as the tympanum between them, are restorations.
