Bede’s account is more consistent. He says that in course of time, Britain, after the Britons and Picts, received a third nation, that of the Scots, into that part of the country occupied by the Picts who came from Ireland under their leader Reuda, and either by friendly arrangement or by the sword acquired those seats among the Picts which they still possess, and that from their leader Reuda they were termed ‘Dalreudini.’ He adds, that ‘Hibernia’ or Ireland was the native country of these Scots, and that their new settlement was on the north side of that arm of the sea which formerly divided the Britons from the Picts, and where the Britons still have their chief fastness, the city called ‘Alcluith.’[135] There is no doubt that Alcluith is the rock in the Clyde on which Dumbarton Castle is situated; the Firth of Clyde, the arm of the sea in question; and that Bede correctly describes the position of the Scottish settlement in his own day, as well as its name of Dalriada, from which he deduces his Reuda as their ‘Eponymus.’ The notices of the Scots by the Roman writers are quite in harmony with these traditionary accounts. They make their first appearance in 360, when they joined the Picts and the Saxons in assailing the Roman province. It is true that an expression of the Roman historian may be held to imply that they had first appeared on the scene seventeen years earlier, in the year 343; but that part of Ammianus’s work is lost, and we have no distinct account of what took place when Constans visited Britain in that year. When Theodosius drove back the invading tribes after their eight years’ occupation of the province, we are clearly told by Claudian that the Scots were driven back to ‘Ierne’ or Ireland; and throughout all the subsequent incursions in which the Scots took part, he implies that it was from thence they were made.
