In Roman times Caerleon was a see, which seems to have embraced the whole of Wales. Then there were five principalities, each of which had a bishop. These were Bangor, Llanelwy (St. Asaph's), St. David's, Llandaff and Llanbadarn, afterwards incorporated with St. David's. Judging from the number of the names of saints which occur in Welsh nomenclature, we may conclude that the Welsh Church was famous for its zeal and activity and for the holiness of its members. It sent preachers and missionaries to Ireland, to Brittany, and Cornwall and Devon. It founded colleges and schools, and the great Celtic Church assisted in the conversion of the Northern Saxons of England, and even sent missionaries to the Continent. By degrees the British Church became merged in the English, founded by Augustine, and with the appointment of Norman prelates in the time of the Conqueror, any lingering survivals of ancient customs and usages were lost, and the unity of the church fully established. The earliest bishop of the See of Llandaff whose name is recorded was St. Dubricius. He is reputed to have founded the see in 612 A.D., but his successor, St. Teilo, seems to have had the chief credit of accomplishing the work. Of course the mythical King Lucius is dragged in as the earliest founder, but we have always neglected the legends connected with him. Of the early Welsh bishops we have no sure information, though there is the famous _Book of Llandaff_, which does not afford much certain knowledge, and is full of inaccuracies. Bishop Urban was consecrated in 1107, conveyed here the relics of Dubricius, and began to rebuild his Cathedral, for which an indulgence was granted by the Archbishop of Canterbury to all who should assist him in the work. Possibly it was finished in his time, but we have no certain information, and the stones of the church can alone tell the story of its building. During the thirteenth century the western part of the nave was erected, and also the chapter-house, which is of Early English design. During the Decorated period the Lady Chapel was added and the presbytery rebuilt, and the walls of the aisles also renewed. The north-west tower was erected in the Perpendicular period by the Earl of Pembroke, uncle of Henry VII. Thus the church was completed. It was not a very beautiful structure, and time has dealt hardly with it. The spoilers at the Reformation plundered it; decay and desolation reigned in the deserted "long-drawn aisle." Some bishops seem to have attempted to do something, but the whole condition of the church was deplorable. Then the troubles of the Civil War period fell upon this Job-like structure, and in spite of some attempts to improve its condition at the Restoration, and at subsequent periods, it still remained in a ruinous state. Then in 1723, when the taste for Italian models was rampant, the authorities erected an Italian temple-like building at the east end. This happily has been entirely removed
