The first authentic Irish immigration into Scotland seems to have taken place about the year of our Lord 258. The pioneers crossed over from Antrim to Argyle, where the strait is less than twenty-five miles wide. Other adventurers followed at intervals, but it is a fact to be deplored, that no passages in our own, and in all other histories, have been so carelessly kept as the records of emigration. The movements of rude masses of men, the first founders of states and cities, are generally lost in obscurity, or misrepresented by patriotic zeal. Several successive settlements of the Irish in Caledonia can be faintly traced from the middle of the third till the beginning of the sixth century. About the year 503, they had succeeded in establishing a flourishing principality among the cliffs and glens of Argyle. The limits of their first territory cannot be exactly laid down; but it soon spread north into Rosshire, and east into the present county of Perth. It was a land of stormy friths and fissured headlands, of deep defiles and snowy summits. "'Tis a far cry to Lough Awe," is still a lowland proverb, and Lough Awe was in the very heart of that old Irish settlement. The earliest emigrants to Argyle were Pagans, while the latter were Christians, and were accompanied by priests, and a bishop, Kieran, the son of the carpenter, whom, from his youthful piety and holy life, as well as from the occupation followed by his father, is sometimes fancifully compared to our Lord and Saviour himself. Parishes in Cantyre, in Islay, and in Carrick, still bear the name of St. Kieran as patron. But no systematic attempt—none at least of historic memory—was made to convert the remoter Gael and the other races then inhabiting Alba—the Picts, Britons, and Scandinavians, until the year of our era, 565, Columba or COLUMBKILL, a Bishop of the royal race of Nial, undertook that task, on a scale commensurate with its magnitude. This celebrated man has always ranked with Saint Patrick and Saint Bridget as the most glorious triad of the Irish Calendar. He was, at the time he left Ireland, in the prime of life—his 44th year. Twelve companions, the apostolic number, accompanied him on his voyage. For thirty-four years he was the legislator and captain of Christianity in those northern regions. The King of the Picts received baptism at his hands; the Kings of the Scottish colony, his kinsmen, received the crown from him on their accession. The islet of I., or Iona, as presented to him by one of these princes. Here he and his companions built with their own hands their parent-house, and from this Hebridean rock in after times was shaped the destinies, spiritual and temporal, of many tribes and kingdoms.
