The old story about promiscuous marriages, which in Cæsar's time was told of the Britons, and later on, when Britain became better known to the Romans, was told of the islands of western Scotland, continued until the fifth century to be told of the Irish, who, like the Hebrideans, dwelt beyond the bounds of the Empire. St. Jerome writes that "the Scotti and Atecotti, in the manner of Plato's Republic, have wives promiscuously and children in common"; and again, "the nation of the Scotti do not marry wives of their own; as if they had read Plato's Republic and adopted the example of Cato, no wife among them belongs to a particular husband; but each according to his pleasure they live without restraint, as cattle live." There is no mention of these evil customs a half-century later when Saint Patrick tells how he won over the Scots and their children from Paganism, and the oldest traditions show that the pagan Irish followed the law of monogamy with as much fidelity as did the ancient Greeks and Romans. St. Jerome tells another story, this time on his own direct testimony: "In my early youth in Gaul I have myself seen the Scots, a Britannic nation, feeding on human flesh, and, when they might find herds of swine and cattle through the forests, [I have known them] to be wont to cut off the hips of shepherds and the breasts of women, and to regard these as the only delicacies of their food." Instead of Scotti, some texts of Saint Jerome have Atecotti in this place. It matters little, for all agree in adding the words _gentem Britannicam_ "a Britannic nation." We have seen that the Atecotti were associated with the Scotti in raiding Roman Britain, and we must come later to the question, who were the Atecotti. St. Jerome's testimony is valuable on the point that these invaders of Roman Britain, whether Scotti or Atecotti, also roved about Gaul. We may take it that there were bands of them in the woods, in which he tells us they might have found swine and cattle to provide them with food, had it not been for their barbarous preference for special cuts of shepherd and shepherdess. He states that he was a boy at the time (_adolescentulus_). He does not say that he saw the barbarians in the act of catching and killing a shepherd or a shepherdess, and we may be certain that he did not, otherwise he would not have stayed on to see the preparation and consumption of the tit-bits. It has been suggested that he was probably accompanied by a very wise elderly woman who told him, as a precaution, the sort of people these roving banditti were, and that his childish imagination confirmed the tale. He may have seen the wandering islanders feasting round their fire in the forest, but how did he contrive to identify the viands? Once more, let it be said that tradition is old enough and history reaches far enough back to assure us that cannibalism, like promiscuous polygamy, was no custom of the inhabitants of Ireland or
