{23} In some cases, _e.g._, at Westminster, in many Cistercian churches, and in Spanish cathedrals, the stalls were not placed under the central tower, but still more to the west, wholly in the nave. In Gothic days, however, in English plans--Westminster is French in plan--the tendency was more and more to place the choir of the monastic and collegiate churches in the eastern limb, just as in a parish church. In the cathedrals the precedent was first set at Canterbury, where in 1096 Prior Ernulph set out a new eastern limb consisting of an eastern apse preceded by no less than nine bays. Sometimes there was a special reason for the removal of the choir from the crossing and the nave. In several cases--in pious recollection of the burial of many a martyr in Early Christian days down in the catacombs of Rome--the Italian practice of constructing a crypt beneath the eastern limb was followed. This had been so as early as St Wilfrid, 671-678, whose crypts at Ripon and Hexham still survive, and in the Anglo-Saxon cathedrals of Winchester, Worcester, Rochester, Gloucester, Canterbury, York, and Old St Paul's. And when these were remodelled by the Norman conquerors, in all cases the crypt was reproduced. Such crypts of course necessitate the building of the eastern limb at a higher level than crossing and nave; in some cases, _e.g._, at Canterbury, the difference in height is very considerable. The result must have been that where as at Canterbury the sanctuary was a long one, the High altar at its east end must have been invisible, or nearly so, to monks seated in the crossing and nave. Consequently, first at Canterbury _c._ 1100, in the thirteenth century at Rochester, Old St Paul's and Worcester, and in the fourteenth century at Winchester and York, the stalls were removed to the eastern limb, the western portion of which now became choir. The only exception among cathedrals with crypts is Gloucester, where the crypt is low and the eastern limb is short and where the stalls remain to this day beneath the central tower. The example set by cathedrals with crypts was soon followed by churches of every degree which had none; whether Benedictine, such as at Chester, Augustinian, as at Carlisle, or served by Secular Canons, as at Exeter. And so in the churches of monks, regular canons and secular canons alike, most of the ecclesiastical authorities reverted to what had been all along the normal plan of the English parish church, viz., an eastern limb containing choir as well as presbytery.[9] {24} [Illustration: Chester] {25}
