Twelve years had now elapsed since Columba first set foot on the island of Iona, and he had already to a great extent accomplished the task he had set before him. He had founded his monastery in the island, as the central point of his mission; and the exhibition of the Christian life, as alone it was possible to present it in the state of society which prevailed among these pagan tribes, as a colony of tonsured monks following a monastic rule, had its usual effect in influencing the population of the adjacent districts. He had converted and baptized the most powerful monarch that ever occupied the Pictish throne, and secured his friendship and support; and this was soon followed by the whole nation ostensibly professing the Christian faith. He had succeeded in re-establishing the Irish colony of Dalriada in the full possession of its territories, and obtained from the _Ardri_, or supreme king of Ireland, the recognition of its independence. He now found himself occupying a position of great influence and authority both in Ireland and Scotland—as the founder of numerous monasteries in the former, and as the acknowledged head of the Christian Church in the latter. Adamnan tells us that he had founded monasteries within the territories both of the Picts and of the Scots of Britain, who are separated from each other by the great mountain range of Drumalban.[252] These monasteries, as well as those which he had founded in Ireland, regarded the insular monastery of Iona as the mother church, and as having, as such, a claim to their obedience; and became subject to her jurisdiction, while their inmates constituted the great monastic fraternity which was termed the _Muintir Iae_, or family of Iona, in the extended sense of the term. Adamnan mentions only a few of these monasteries, and gives no details which might enable us to fix the exact date of their foundation; though we can gather from his narrative that some of them existed during the earlier years of his mission, and all must, of course, have been founded at some period during the thirty-four years of his life in Iona.
