How great a man was the Irish monk Crimthan, called Colum, the Dove: Columcille, the Dove of the Church. One may read all that has been written of him since the sixth century, and not reach the depths of his nature. I doubt if any other than a Gael can understand him aright. More than any Celt of whom history tells, he is the epitome of the Celt. In war, Cuchullin himself was not more brave and resourceful. Finn, calling his champions to the pursuit of Grania, or Oìsin boasting of the Fianna before Patrick, was not more arrogant, yet his tenderness could be as his Master's was, and he could be as gentle as a young mother with her child, and had a child's simplicity. He knew the continual restlessness of his race. He was forty-two when he settled in Iona, and had led a life of frequent and severe vicissitude, often a wanderer, sometimes with blood against him and upon his head, once in extremity of danger, an outlaw, excommunicated. But even in his haven of Iona he was not content. He journeyed northward through the Pictish realms, a more dangerous and obscure adventure then than to cross Africa to-day. He sailed to "the Ethican island" as St. Adamnan calls Tiree, and made of it a sanctuary, where prayer might rise as a continual smoke from quiet homes. No fear of the savage clans of Skye--where a woman had once reigned with so great a fame in war that even the foremost champion of Ireland went to her in his youth to learn arms and battle-wisdom--restrained him from facing the island Picts. Long before Hakon the Dane fought the great seafight off Largs on the mainland, Colum had built a church there. In the far Perthshire wilds, before Macbeth slew Duncan the king, the strong abbot of Iona had founded a monastery in that thanedom. At remote Inbhir Nis, the Inverness of to-day, he overcame the King of the Picts and his sullen Druids, by his daring, the fierce magnetism of his will, his dauntless resource. Once, in a savage region, far north-eastward, towards the Scandinavian sea, he was told that there his Cross would not long protect either wattled church or monk's cell: on that spot he built the monastery of Deir, that stood for a thousand years, and whose priceless manuscript is now one of the treasures of Northumbria.
