The Formorians were a civilized race; they had "a fleet of sixty ships and a strong army." The next invader of their dominions was Neimhidh; he captured one of their fortifications, but it was retaken by the Formorians under "Morc." Neimhidh was driven out of the country, and the Atlanteans continued in undisturbed possession of the island for four hundred years more. Then came the Fir-Bolgs. They conquered the whole island, and divided it into five provinces. They held possession of the country for only thirty-seven years, when they were overthrown by the Tuatha-de-Dananns, a people more advanced in civilization; so much so that when their king, Nuadha, lost his hand in battle, "Creidne, the artificer," we are told, "put a silver hand upon him, the fingers of which were capable of motion." This great race ruled the country for one hundred and ninety-seven years: they were overthrown by an immigration from Spain, probably of Basques, or Iberians, or Atlanteans, "the sons of Milidh," or Milesius, who "possessed a large fleet and a strong army." This last invasion took place about the year 1700 B.C.; so that the invasion of Neimhidh must have occurred about the year 2334 B.C.; while we will have to assign a still earlier date for the coming of Partholan's people, and an earlier still for the occupation of the country by the Formorians from the West. In the Irish historic tales called "Catha; or Battles," as given by the learned O'Curry, a record is preserved of a real battle which was fought between the Tuatha-de-Dananns and the Fir Bolgs, from which it appears that these two races spoke the same language, and that they were intimately connected with the Formorians. As the armies drew near together the Fir-Bolgs sent out Breas, one of their great chiefs, to reconnoitre the camp of the strangers; the Tuatha-de-Dananns appointed one of their champions, named Sreng, to meet the emissary of the enemy; the two warriors met and talked to one another over the tops of their shields, and each was delighted to find that the other spoke the same language. A battle followed, in which Nunda, king of the Fir-Bolgs, was slain; Breas succeeded him; he encountered the hostility of the bards, and was compelled to resign the crown. He went to the court of his father-in-law, Elathe, a Formorian sea-king or pirate; not being well received, he repaired to the camp of Balor of the Evil Eye, a Formorian chief. The Formorian head-quarters seem to have been in the Hebrides. Breas and Balor collected a vast army and navy and invaded Ireland, but were defeated in a great battle by the Tuatha-de-Dananns. These particulars would show the race-identity of the Fir-Bolg and Tuatha-de-Dananns; and also their intimate connection, if not identity with, the Formorians.
