It is sufficient for us to find the first men in Spain, remembering that “Spain” stood for the Celtic Hades, or Elysium. In this country Bregon, the father of two sons, Bilé and Ith, had built a watch-tower, from which, one winter’s evening, Ith saw, far off over the seas, a land he had never noticed before. “It is on winter evenings, when the air is pure, that man’s eyesight reaches farthest”, remarks the old tract called the “Book of Invasions”,[145] gravely accounting for the fact that Ith saw Ireland from Spain. Wishing to examine it nearer, he set sail with thrice thirty warriors, and landed without mishap at the mouth of the River Scêné.[146] The country seemed to him to be uninhabited, and he marched with his men towards the north. At last he reached Aileach, near the present town of Londonderry. Here he found the three reigning kings of the people of the goddess Danu, Mac Cuill, Mac Cecht, and Mac Greiné, the sons of Ogma, and grandsons of the Dagda. These had succeeded Nuada the Silver-handed, killed in the battle with the Fomors; and had met, after burying their predecessor in a tumulus called Grianan Aileach, which still stands on the base of the Inishowen Peninsula, between Lough Swilly and Lough Foyle, to divide his kingdom among them. Unable to arrive at any partition satisfactory to all, they appealed to the new-comer to arbitrate. The advice of Ith was moral rather than practical. “Act according to the laws of justice” was all that he would say to the claimants; and then he was indiscreet enough to burst into enthusiastic praises of Ireland for its temperate climate and its richness in fruit, honey, wheat, and fish. Such sentiments from a foreigner seemed to the Tuatha Dé Danann suggestive of a desire to take the country from them. They conspired together and treacherously killed Ith at a place since called “Ith’s Plain”. They, however, spared his followers, who returned to “Spain”, taking their dead leader’s body with them. The indignation there was great, and Milé, Bilé’s son and Ith’s nephew, determined to go to Ireland and get revenge. Milé therefore sailed with his eight sons and their wives. Thirty-six chiefs, each with his shipful of warriors, accompanied him. By the magic arts of their druid, Amergin of the Fair Knee, they discovered the exact place at which Ith had landed before them, and put in to shore there. Two alone failed to reach it alive. The wife of Amergin died during the voyage, and Aranon, a son of Milé, on approaching the land, climbed to the top of the mast to obtain a better view, and, falling off, was drowned. The rest disembarked safely upon the first of May.
