one of the buildings of the Roman station of Corstopitum, as the arch at Escomb was probably removed from the not far distant station of Vinovium. Sec. 14. The date to which these four northern churches may be assigned is the half century of the activity of St Wilfrid in England (664-709 A.D.). Bede's account of the architectural work of Wilfrid's friend, Benedict Biscop, shows that he procured, for the building of the church at Monkwearmouth, stonemasons and glaziers from Gaul, who were acquainted with "the manner of the Romans." The account which another contemporary, Eddius, gives of Wilfrid's church at Hexham, is clear proof that this important building was a reproduction, in plan and elevation, of the aisled basilicas of the continent--a fact in keeping with Wilfrid's life-long aim of bringing English Christianity into closer touch with the main current of historic Christianity in Rome and Gaul. The foundations of the outer walls of most of Wilfrid's church were uncovered when, lately, the new nave of Hexham priory church was begun; but one of its features has been long known, and is of the highest interest. The crypt for relics below the apse and high altar consists of an oblong chamber, with a western vestibule, approached by a straight stairway from the nave. In addition to the western stair, there are two stairs which communicated with the apse. That on the south side remains perfect, and ends in a passage and vestibule, through which the relic-chamber is entered. The northern stairway leads through a passage to the western vestibule, at the foot of the stair from the nave. The crypt of Wilfrid's contemporary basilica at Ripon also remains: here the arrangement is less complicated; but the arrangement of the main relic-chamber is equally the chief feature of the plan.
