Although the roofs of the aisles at Canterbury had been vaulted, the choir itself had a flat boarded ceiling, painted like that still remaining at Peterborough. The vault of the choir of the cathedral of Sens, from whence came William, the architect of the choir of Canterbury, is also an addition of later date. The same change was made in many other churches of that period. The builders of the early Norman period did not venture to erect a vault over so large a space; we do not find any early vault over a space above twenty feet wide, and few of so wide a span. Many of our Norman cathedrals still have timber roofs over the large spaces, and the aisles vaulted. In Normandy vaults were more frequently used than in England, even at this early period; and this was still more the case in subsequent times, for the fine open timber roofs for which some parts of England are distinguished are unknown in Normandy, where almost every village church is vaulted over.

Here it may be well to mention, that down to the early Norman period the eastern limb of a cruciform church, or the chancel of a plain oblong plan, was always short, rarely more than a single square, or at the utmost two squares, in length, and was frequently terminated by a round east end called an apse. Immediately after this period the custom of lengthening the eastern limb of the church became so general, that the original dimensions have been almost lost sight of. The history of nearly every one of our cathedrals gives the same result: first, the choir was lengthened by the addition of a presbytery, and afterwards still further by adding a lady-chapel, which did not come into fashion until quite the end of the twelfth century.

Gervase and William of Malmesbury have furnished us, as we have seen, with a clue by which to distinguish the work of the early Norman period from that of a later age, namely, wide-jointed masonry, and shallow sculpture executed chiefly with the axe instead of the chisel. The best and safest test is the wide-jointed masonry, where it is found; but in some cases the joints can hardly be said to be either wide or fine; they are of a moderate width, and not of marked character either way.

The arch is generally at first not recessed at all, afterwards only once recessed, and the edges are either square, or have a plain round molding cut upon them; the zigzag ornament is used, but not so abundantly as at a later period; the dripstone is frequently ornamented with what is called the hatched molding; the billet is also used, but sparingly, and perhaps not before 1100; it is found in the early parts of Peterborough, but not in the later parts. The head of the door is generally square with a round arch over it, and the intermediate space under the arch, called the tympanum, is either left plain, or ornamented with shallow sculpture of rude character, sometimes preserved from an earlier building.

Rich Doorways form one of the most important features of late Norman work. The examples given from Cuddesdon and Middleton Stoney are good ordinary specimens, such as may be found in scores of parish churches. They are generally round-headed, very deeply recessed, and frequently have shafts in the jambs. The tympanum is frequently filled with rich sculpture, which becomes deeper and better executed as the style advances. The moldings are numerous, but not of much variety in section,
