crossing, the _pulpitum_ was between the eastern piers, the rood-screen between the western. At Canterbury the eastern processional doorway was in the west wall of the transept next the cloister. At Durham it is in the usual position, but covered by a vestibule formed by placing the screen at the end of the south aisle one bay west of the rood-screen. The rood-screens at Croyland and at Tynemouth priory still remain among the ruins. At St Albans the _pulpitum_ is gone, but the stone rood-screen remains; while at Blyth priory the place of the rood-screen was taken by a wall the whole height of the nave. § 36. Lay-folk were permitted to enter the naves of monastic churches; and, even in Cistercian churches, where the whole building was strictly devoted to the uses of the monastery, doorways are sometimes found, as at Kirkstall, which may have been made for this purpose. In a large number of Benedictine and Augustinian churches, though by no means in the majority, an altar in the nave was appropriated to parochial services, and was served by a secular vicar or a curate appointed by the convent. The lay-folk entered the church by a doorway in the aisle opposite the cloister: the great western doorway was used only on special occasions, as in the procession on Palm Sunday or at an episcopal visitation. Sometimes, as at Blyth and Leominster, a special addition of an aisle or a second nave and aisle was made to the original nave, for the sake of parochial services. Such services, however, frequently interfered with the monastic offices, especially if the convent was singing one thing and the parishioners another. At Wymondham in Norfolk a dispute about the use of the bells by the parish led to a serious quarrel in the fifteenth century. The parishioners fastened up the rood-screen doors and appropriated the nave, and the dispute was healed only by the building of a separate bell-tower for the parish at the west end of the church. The monks of Rochester and the canons of Holy Trinity, Aldgate, built churches within their outer precincts for the parishioners whose services interfered with their own. This arrangement, like that by which the pairs of parish churches at Coventry, Evesham and Bury St Edmunds were distinct from the monastery churches hard by, put an end to such constant wrangling as occurred between monks and lay-folk over the use of the south transept at Chester.
