What renders it more surprising still is, that individually they had no aversion to a seafaring life; not only many of them subsisted by fishing, but their _curraghs_ covered the sea all along their extensive coasts. They could pass from island to island in their small craft. Thus the Celts of Erin frequently crossed over to Scotland, to the Hebrides, from rock to rock, and in Christian times they went as far as the Faroe group, even as far as Iceland, which some of them appear to have attempted to colonize long before the Norwegian outlaws went there; and some even say that from Erin came the first Europeans who landed on frozen Greenland years before the Icelandic Northmen planted establishments in that dreary country. The Celts, therefore, and those of Erin chiefly, were a seafaring race. But to construct a fleet, to provision and arm it, to fill it with the flower of their youth, and send them over the ocean to plunder and slay the inhabitants for the purpose of colonizing the countries they had previously devastated, such was never the character of the Celts. They never engaged extensively in trade, or what is often synonymous, piracy. Before becoming christianized, the Celts of Ireland crossed over the narrow channel which divided them from Britain, and frequently carried home slaves; they also passed occasionally to Armorica, and their annals speak of warlike expeditions to that country; but their efforts at navigation were always on an extremely limited scale, in spite of the many inducements offered by their geographical position. The fact is striking when we compare them in that particular with the Scandinavian free-rovers of the Northern Ocean. It is, therefore, very remarkable that, whenever they got on board a boat, it was always a single and open vessel. They did so in pagan times, when the largest portion of Western Europe was theirs; they continued to do so after they became Christians. The race has always appeared opposed to the operations of an extensive commerce, and to the spreading of their power by large fleets. The ancient annals of Ireland speak, indeed, of naval expeditions; but these expeditions were always undertaken by a few persons in one, two, or, at most, three boats, as that of the sons of Ua Corra; and such facts consequently strengthen our view. The only fact which seems contradictory is supposed to have occurred during the Danish wars, when Callaghan, King of Cashel, is said to have been caught in an ambush, and conveyed a captive by the Danes, first to Dublin, then to Armagh, and finally to Dundalk.
