It is a pity that the annalists, who tell us so many things we neither care to hear nor much believe in, should have left us no record of any assault of the Northmen against one of these redoubtable towers. Even at the present day they would, without ammunition, be remarkably difficult nuts to crack; indeed, it is hard to see how their assault could have been successfully attempted, save by the slow process of starvation, or possibly by fires kindled immediately below the entrance, and so by degrees smoking out their inmates.
If any one ever succeeded in getting into them, we
may be sure the Land Leapers did! Before long they appear to have gathered nearly the whole spoil of the country into the towns, which they built and fortified for themselves at intervals along the coast. Cork, Waterford, Limerick, Wexford, and Dublin, all owe their origin in the first instance to the Northmen; indeed it is a curious fact that Dublin can never be said, save for very short periods to have belonged to the Irish at all. It was first the capital of their northern invaders, and afterwards that, of course, of the English Government.
Three whole centuries the Danish power lasted, and internecine war raged, a war during which almost every trace of earlier civilizing influences, all those milder habits and ways of thought, which Christianity had brought in and fostered, perished well-nigh utterly. The ferocity of the invaders communicated itself to the invaded, and the whole history is one confused and continual chronicle of horrors and barbarities.
An important distinction must be made at this point between the effects of the Northern invasion in England and in Ireland. In the former the invaders and natives became after a while more or less assimilated, and, under Canute, an orderly government, composed of both nationalities, was, we know, established. In Ireland this was never the case. The reason, doubtless, is to be found in the far closer similarity of race in the former case than the latter. In Ireland the "Danes," as they are popularly called, were always strangers, heathen tyrants, hated and despised oppressors, who retorted this scorn and hatred in the fullest possible measure upon their antagonists. From the moment of their appearance down to the last we hear of them--as long, in fact, as the Danes of the seaport towns retained any traces of their northern origin--so long they continued to be the deadly foes of the rest of the island.
Even where the Northmen accepted Christianity, it does not appear to have had any strikingly ameliorating effect Thus we read that Godfrid, son of Sitric, embraced Christianity in 948, and in the very next year we discover that he plundered and burnt all the churches in East Meath, killing over a hundred people who had taken refuge in them, and carrying off a quantity of captives. Land-leaping, too, continued in full force. "The godless hosts of pagans swarming o'er the Northern Sea," continued to arrive in fresh and fresh numbers from their inexhaustible Scandinavian breeding grounds--from Norway, from Sweden, from Denmark, even, it is said, from Iceland. The eighth, ninth, and tenth centuries are, in fact, the great period all over Europe for the incursions of the Northmen--high noon, so to speak, for those fierce and roving sons of plunder,--"People," says an old historian quaintly, "desperate in attempting the conquest of other Realmes, being very sure to finde warmer dwellings anywhere than in their own homes."
