Internally, the church is divided from west to east, in ancient monastic fashion, into (1) nave, (2) choir, (3) sanctuary, (4) Saints’ chapel, (5) retro-choir or ante-chapel, (6) Lady chapel. (1) The ritual nave occupies the ten western bays only of the architectural nave, and terminates at the Holy Rood screen. (2) The ritual choir is not placed in the eastern limb; but, following a far more ancient precedent, in the three eastern bays of the architectural nave, and in the crossing (that part of the transept which is beneath the central tower). This was the place of the choir in the primitive basilicas, and in the early monastic churches. The “Coro” of the Spanish cathedrals is still placed in the nave. The same arrangement survives in this country in Westminster Abbey and Norwich, and has lately been restored at Peterborough. (3) The sanctuary extends from the tower to the great reredos, and provided a free and unencumbered space in front of the high altar, which “dwelt apart.” (4) The Saint’s chapel was occupied, like the feretory at Winchester, by magnificent shrines which towered behind and above the high altar, visible far down the nave, at least before the great reredos was erected. (5) The retro-choir or ante-chapel provided a processional path, or ambulatory, or eastern choir aisle at the back of the shrines. Romsey and Hereford possess the earliest of these processional paths, Winchester the largest. (6) The Lady chapel occupies its normal position, to the extreme east. But where there was no room for farther eastward extension of the cathedral, the Lady chapel may be found on the north or south side of the choir, as at Bristol and Oxford. Here, as at Salisbury and Winchester, the high roofs do not extend over retro-choir and Lady chapel, which are only one story high; at York and Lincoln and Ely, the church retains its full height uninterruptedly to the extreme east end; the ritualistic divisions of the church being marked by screens only. [Illustration: LADY-CHAPEL LOOKING EAST.] In Norman times the church did not extend so far eastward. The sanctuary ended in three semicircular apses, of which those of the aisles were semicircular inside but square outside, as at Romsey. And, in lieu of eastern aisles, the transepts had each a pair of little semicircular chapels, the arches leading into which may still be seen in their eastern walls.
