Chapter IV

THE IRISH MYTHOLOGICAL CYCLE.

The Tuatha Dé Danann remained masters of Ireland until the coming of the Milesians, so named from an eponymous Mile, son of Bile. Ith, having been sent to reconnoitre, was slain, and the Milesians now invaded Ireland in force. In spite of a mist raised by the Druids, they landed, and, having met the three princes who slew Ith, demanded instant battle or surrender of the land. The princes agreed to abide by the decision of the Milesian poet Amairgen, who bade his friends re-embark and retire for the distance of nine waves. If they could then effect a landing, Ireland was theirs. A magic storm was raised, which wrecked many of their ships, but Amairgen recited verses, fragments, perhaps, of some old ritual, and overcame the dangers. After their defeat the survivors of the Tuatha Dé Danann retired into the hills to become a fairy folk, and the Milesians (the Goidels or Scots) became ancestors of the Irish.

The strife of Fomorians and Tuatha Dé Danann suggests the dualism of all nature religions. Demons or giants or monsters strive with gods in Hindu, Greek, and Teutonic mythology, and in Persia the primitive dualism of beneficent and hurtful powers of nature became an ethical dualism—the eternal opposition of good and evil. The sun is vanquished by cloud and storm, but shines forth again in vigour. Vegetation dies, but undergoes a yearly renewal. So in myth the immortal gods are wounded and slain in strife. But we must not push too far the analogy of the apparent strife of the elements and the wars of the gods. The one suggested the other, especially where the gods were elemental powers. But myth-making man easily developed the suggestion; gods were like men and "could never get eneuch o' fechtin'." The Celts knew of divine combats before their arrival in Ireland, and their own hostile powers were easily assimilated to the hostile gods of the aborigines.

After their conversion, the Celts, sons of Milesius, thought that the gods still existed in the hollow hills, their former dwellings and sanctuaries, or in far-off islands, still caring for their former worshippers. This tradition had its place with that which made them a race of men conquered by the Milesians—the victory of Christianity over paganism and its gods having been transmuted into a strife of races by the euhemerists. The new faith, not the people, conquered the old gods. The Tuatha Dé Danann became the Daoine-sidhe, a fairy folk, still occasionally called by their old name, just as individual fairy kings or queens bear the names of the ancient gods. The euhemerists gave the Fomorians a monstrous and demoniac character, which they did not always give to the Tuatha Dé Danann; in this continuing the old tradition that Fomorians were hostile and the Tuatha Dé Danann beneficent and mild.
