Then the saintly Dubricius, who for a long time had wanted to live as a hermit, resigned from his position as Archbishop. David, the King's uncle, whose way of life had afforded an example of unblemished virtue to those whom he had instructed in the faith, was consecrated in his place. At the same time Tebaus, the celebrated priest of Llandaff, was appointed in the place of the holy Sampson, Archbishop of Dol: this with the approval of Hoel, King of the Armorican Britons, to whom Tebaus' life and saintly habits had commended him. The bishopric of Silchester was given to Maugannius, that of Winchester to Diwanius and that of Alclud to Eledenius.[IX.15]

LLANDAFF appears only once in the Historia, when Arthur, at his plenary court in CAERLEON, makes various ecclesiastical appointments. There has been a Christian community in the area since the sixth century: see the history page of the Llandaff Cathedral site for more details.
