The interior of the church has been much modernized, but still enough remains to render the whole scheme intelligible. The arcades between the nave and aisles are all perfect; they are very plain, but spring from carved capitals of large size. The capitals of the nave arcades have their abaci planned with re-entering angles, so as exactly to fit the plan of the two square orders of the archivolt. Some of the caps are of foliage only, others are _historiés_; one I remember having all round it the Adoration of the Magi, who are represented as large figures on horseback, and produce a most strange effect in such a place. The cross arches under the lantern are old, as also are those across the aisles, but the roof of the nave is now all under-drawn with plaster, and there are no means of telling precisely how it was originally covered; but, on the whole, I incline to the belief that it must have had a cylindrical vault, with quadrant vaults in the aisles, though it is possible, of course, that it had a flat wooden ceiling. The square piers in the nave favour this alternative, inasmuch as they seem to rise higher than they would have done had the roof been a stone vault. The pilasters against the aisle walls also run up to the level of the plate inside, and this (though it is modern) is higher than the springing of the nave arcades, and seems to prove that there have never been cross arches in the aisles. The external walls of the aisles above the cloister roofs are arcaded with plain arches between the pilasters, by which it is divided into bays, and the aisle windows are set within these arches. The lantern is modernized, but there still remain coupled cross ribs on its under side, and these, though they are plastered, being similar to those under the central vault of the Templars’ Church, are probably original. I wish much that I could put my hands on some documentary evidence which would fix the exact date of this very fine and interesting church, for, from its importance, it may be considered to be a leading example; and there is no doubt that it very largely influenced the other churches of this important city. It is possible, however, from the character of some of the detail, that part of it is older than the Templars’ Church, consecrated, as we have seen, in A.D. 1208; though other parts of the detail--as, for instance, that of the external cornices--cannot be earlier than A.D. 1250-1270. Before the last of these dates, therefore, I have no doubt the church was erected, though, as the arches are all, or nearly all, semi-circular, the greater part of the work was probably finished early in the century, if not in the twelfth century, and the decorations may have been completed afterwards.[193]
