This fifth and final colony called themselves alternately, or at different periods of their history, _Gael_, from one of their remote ancestors; _Milesians_, from the immediate projector of their emigration; or _Scoti_, from Scota, the mother of Milesius. They came from Spain under the leadership of the sons of Milesius, whom they had lost during their temporary sojourn in that country. In vain the skilful _Tuatha_ surrounded themselves and their coveted island with magic-made tempest and terrors; in vain they reduced it in size so as to be almost invisible from sea; Amergin, one of the sons of Milesius, was a Druid skilled in all the arts of the east, and led by his wise counsels, his brothers countermined the magicians, and beat them at their own weapons. This Amergin was, according to universal usage in ancient times, at once Poet, Priest, and Prophet; yet when his warlike brethren divided the island between them, they left the Poet out of reckoning. He was finally drowned in the waters of the river Avoca, which is probably the reason why that river has been so suggestive of melody and song ever since. Such are the stories told of the _five_ successive hordes of adventurers who first attempted to colonize our wooded Island. Whatever moiety of truth may be mixed up with so many fictions, two things are certain, that long before the time when our Lord and Saviour came upon earth, the coasts and harbours of Erin were known to the merchants of the Mediterranean, and that from the first to the fifth Christian century, the warriors of the wooded Isle made inroads on the Roman power in Britain and even in Gaul. Agricola, the Roman governor of Britain in the reign of Domitian—the first century—retained an Irish chieftain about his person, and we are told by his biographer that an invasion of Ireland was talked of at Rome. But it never took place; the Roman eagles, although supreme for four centuries in Britain, never crossed the Irish Sea; and we are thus deprived of those Latin helps to our early history, which are so valuable in the first period of the histories of every western country, with which the Romans had anything to do. CHAPTER II. THE FIRST AGES. Since we have no Roman accounts of the form of government or state of society in ancient Erin, we must only depend on the Bards and Story-tellers, so far as their statements are credible and agree with each other. On certain main points they do agree, and these are the points which it seems reasonable for us to take on their authority.
