Christianity, following the Roman rule, completed the ruin of paganism in Britain, so far, at least, as its public manifestations were concerned. In the sixth century of our era, the monkish writer, Gildas, is able to refer complacently to the ancient British religion as a dead faith. “I shall not”, he says, “enumerate those diabolical idols of my country, which almost surpassed in number those of Egypt, and of which we still see some mouldering away within or without the deserted temples, with stiff and deformed features as was customary. Nor will I cry out upon the mountains, fountains, or hills, or upon the rivers, which now are subservient to the use of men, but once were an abomination and destruction to them, and to which the blind people paid divine honour.”[562] And with the idols fell the priests. The very word “druid” became obsolete, and is scarcely mentioned in the earliest British literature, though druids are prominent characters in the Irish writings of the same period. The secular arm had no power in Scotland and in Ireland, consequently the battle between Paganism and Christianity was fought upon more equal terms, and lasted longer. In the first country, Saint Columba, and in the second, Saint Patrick are the personages who, at any rate according to tradition, beat down the druids and their gods. Adamnan, Abbot of Iona, who wrote his _Vita Columbæ_ in the last decade of the seventh century, describes how, a century earlier, that saint had carried the Gospel to the Picts. Their king, Brude, received him contemptuously, and the royal druids left no heathen spell unuttered to thwart and annoy him. But, as the power of Moses was greater than the power of the magicians of Egypt, so Saint Columba’s prayers caused miracles more wonderful and more convincing than any wrought by his adversaries. Such stories belong to the atmosphere of myth which has always enveloped heroic men; the essential fact is that the Picts abandoned the old religion for the new. A similar legend sums up the life-work of Saint Patrick in Ireland. Before he came, Cromm Cruaich had received from time immemorial his yearly toll of human lives. But Saint Patrick faced the gruesome idol; as he raised his crozier, we are told, the demon fell shrieking from his image, which, deprived of its soul, bowed forward to the ground.
