their caps and bases, both of the north and south sides of the chapel, are of later character, those of the south side being similar to the corresponding features of the nave and those of the north side resembling the same features in the lower church, and having been, doubtless, renewed when the lower church was re-erected. The floor of this south-west chapel is 15 inches above the level of that of the lower church. The exterior base differs in design from that of the rest of the lower church, and indicates an earlier date. Mr. Honeyman is of opinion that when the south staircase to the lower church was erected this small chapel stood in the way, and prevented the stair from being carried out in the same manner as that on the north side, which was executed according to the architect’s design. The eastern wall of the chapel was afterwards cut through so as to provide access from the south stair to the lower church. The north staircase to the lower church was not impeded, as the south one was, by the above chapel, but was carried out according to the architect’s design, and possesses a handsome early pointed doorway, where it enters the lower church. Mr. Honeyman then goes on to show that the same base as existed on the outside of the ancient south-west chapel is continued round the nave, which fact supports his view that the nave was founded and the walls partly erected before the choir was built by Bishop Bondington. As pointed out by Mr. Honeyman, the bases of the vaulting shafts and part of the side walls of the nave aisles (more on the north side than the south side) were apparently executed at an earlier date than the choir. “The bases of the shafts on the bench-table of the aisles, with their delicate mouldings and square plinths, belong to an earlier period than anything to be seen in the choir.” But when Bishop Bondington came on the scene and resolved to reconstruct the whole choir, the work at the nave was stopped, not to be resumed for about a century.
