These things happened in the province of the Bernicians; but in that of the Deiri also, where he was wont often to be with the king, he baptized in the river Swale, which runs by the village of Cataract;(241) for as yet oratories, or baptisteries, could not be built in the early infancy of the Church in those parts. But in Campodonum,(242) where there was then a royal township, he built a church which the pagans, by whom King Edwin was slain, afterwards burnt, together with all the place. Instead of this royal seat the later kings built themselves a township in the country called Loidis.(243) But the altar, being of stone, escaped the fire and is still preserved in the monastery of the most reverend abbot and priest, Thrydwulf, which is in the forest of Elmet.(244) Chap. XV. How the province of the East Angles received the faith of Christ. [627-628 A.D.] Edwin was so zealous for the true worship, that he likewise persuaded Earpwald, king of the East Angles, and son of Redwald, to abandon his idolatrous superstitions, and with his whole province to receive the faith and mysteries of Christ. And indeed his father Redwald had long before been initiated into the mysteries of the Christian faith in Kent, but in vain; for on his return home, he was seduced by his wife and certain perverse teachers, and turned aside from the sincerity of the faith; and thus his latter state was worse than the former; so that, like the Samaritans of old, he seemed at the same time to serve Christ and the gods whom he served before; and in the same temple he had an altar for the Christian Sacrifice, and another small one at which to offer victims to devils. Aldwulf,(245) king of that same province, who lived in our time, testifies that this temple had stood until his time, and that he had seen it when he was a boy. The aforesaid King Redwald was noble by birth, though ignoble in his actions, being the son of Tytilus, whose father was Uuffa, from whom the kings of the East Angles are called Uuffings.(246)
