Adamnan’s first visit to Northumbria was made in the year 686; but we know nothing of it beyond the fact that the object of it was to redeem from Aldfrid the captives who had been carried off from Ireland by his predecessor, King Ecgfrid. Cudberct was at this time bishop of Lindisfarne, and it is extremely probable that they met. Adamnan’s second visit, however, was in 688, after Cudberct’s death, but while the whole kingdom was still full of his memory and the report of his sayings and doings; and these may have probably had their effect in bringing Adamnan over to the adoption of the Roman system, of which Cudberct had latterly been such a strenuous supporter. Bede tells us that, through his efforts, a great part of the Scots in Ireland, and some also of the Britons in Britain, conformed to the proper and ecclesiastical time of keeping Easter. By the latter expression, the Britons of Strathclyde, who had recently regained their freedom from the yoke of the Angles, are meant,[417] as the Britons of North Wales did not conform till the year 768, nor those of South Wales till the year 777. With the Britons of Strathclyde, too, we may connect at this time Sedulius as their bishop, who was present at a council held at Rome in the year 721, under Pope Gregory II., and subscribes its canons as Sedulius, a bishop of Britain of the nation of the Scots.[418] The Strathclyde Britons therefore, on regaining their independence, appear to have obtained a bishop from Ireland, probably from the southern Scots; and his presence at this council proves that he was of the Roman party.
