Three years after this defeat, St. Columba came over from Ireland to Britain to con- vert the northern Picts. And we are now on historic ground, as his biographer Adomnan states that he appeared on his arrival, " coram Conallo rege, filio " Comgall." Bede and Walafred Strabo state that the island of lona was given to Columba by the Picts ; on the other hand, Tighernac states that it was given to him by Conall, king of Dalriada ; but if lona and the neighbouring islands formed a part of the territory which had been at first overrun by Scots, and from which they had been afterwards expelled by the Picts, it is intelligible enough that the British historians should have recorded the grant as having been made by the Picts, and that the Irish annalists should have equally confidently asserted that it had been made by the king of Dabiada.
