remembered, the eastern arm was, not in those days, as afterwards became customary, the choir, but rather the sanctuary, or, more correctly, the sanctuary and presbytery conjoined. The choir,--that is to say, the stalls for the monks or canons who sat in choir,--was under the central tower, and often ran a little into what we call the nave. It resulted from this that, in cases where funds did not permit the completion at first of the entire building, it was customary to build from the east end up to the second or third pillar of the nave, so as to provide for the actual requirements, and also to give an abutment to the central tower. [Illustration: Fig. 259.--Plan, Ely Cathedral.] Abbot Symeon’s plan was formed on the largest scale (Fig. 259). His transepts had each four bays in length, and, like those of his brother’s church at Winchester, were aisled on both sides. He also built the gallery across the transept, as at Canterbury and at Winchester. His eastern arm was of four full bays, added to which was a smaller bay and an unaisled apse. The aisles of the eastern arm were square-ended. The pillars of the transept were generally round, though in some cases clustered, and their capitals were totally different from those used by his brother, being a quaint reminiscence of the Corinthian. The proportions of the interior, in point of height, differ from those of Winchester; and it would seem, that the height being divided into three, one was here given to the gallery or triforium, the remainder being divided between the great arcade and the clerestory, with proportions of four to three; so that the main arcade retaining the same proportion as at Winchester, there is more triforium and less clerestory, differences which were increased in building the nave. The galleries, originally built across the ends of the transepts, were removed during later, though still Norman, times; and an arcade of slight projection substituted. The clerestory differs from Winchester in the arches of the three openings springing at equal height, and the plans of the piers differ considerably. Those in the transepts (as before said) are round and clustered, the latter consisting of the customary group of three shafts on its lateral faces, with a single shaft at back and front, for the vaulting and the roof, making together a perfectly uniform group of four larger and four smaller shafts (Fig. 260). The round columns have a shafted pilaster attached to them on the side facing the aisle (Fig. 261). [Illustration: Fig. 260. Fig. 261. Transept Piers, Ely Cathedral.]
