Matters reached a crisis when the poet Coirpné came to demand hospitality and was shown "into a little house, small, narrow, black, dark, where was neither fire nor furniture nor bed. He was given three little dry loaves on a little plate. When he rose in the morning he was not thankful." He gave vent then to the first satire ever uttered in Ireland, which is still preserved in eight lines which would be absolutely unintelligible except for the ancient glosses.
After this the people of the De Danann race demanded the abdication of Breas, which he had promised in case his reign did not please them. He acknowledged his obligation to them, but requested a delay of seven years, which they allowed him, on condition that he gave them guarantees to touch nothing belonging to them during that time, "neither our houses nor our lands, nor our gold, nor our silver, nor our cattle, nor anything eatable, we shall pay thee neither rent nor fine to the end of seven years." This was agreed to.
But the intention of Breas in demanding a delay of seven years was a treacherous one; he meant to approach his father's kindred the Fomorians, and move them to reinstate him at the point of the sword. He goes to his mother who tells him who his father is, for up to that time he had remained in ignorance of it; and she gives him a ring whereby his father Elatha, a king of the Fomorians, may recognise him. He departs to the Fomorians, discovers his father and appeals to him for succour. By his father he is sent to Balor, a king of the Fomorians of the Isles of Norway—a locality probably ascribed to the Fomorians after the invasions of the Northmen—and there gathered together an immense army to subdue the Tuatha De Danann and give the island to their relation Breas.
In the meantime Nuada, whose hand had been replaced by a silver one, reascends the throne and is joined by Lugh of the Long-hand, the "Ildana" or "man of various arts." This Lugh was a brother of the Dagda and of Ogma, and is perhaps the best-known figure among the De Danann personalities. Lugh and the Dagda and Ogma and Goibniu the smith and Diancécht the leech met secretly every day at a place in Meath for a whole year, and deliberated how best to shake off the yoke of the Fomorians. Then they held a general meeting of the Tuatha De and spoke with each one in secret.
"'How wilt thou show thy power?' said Lugh, to the sorcerer Mathgen.
"'By my art,' answered Mathgen, 'I shall throw down the mountains of Ireland upon the Fomorians, and they shall fall with their heads to the earth;' then told he to Lugh the names of the twelve principal mountains of Ireland which were ready to do the bidding of the goddess Dana[9] and to smite their enemies on every side.
"Lugh asked the cup-bearer: 'In what way wilt thou show thy power?'
"'I shall place,' answered the cup-bearer, 'the twelve principal lakes of Ireland under the eyes of the Fomorians, but they shall find no water in them, however great the thirst which they may feel;' and he enumerated the lakes, 'from the Fomorians the water shall hide itself, they shall not be able to take a drop of it; but the same lakes will furnish the Tuatha De Danann with water to drink during the whole war, though it should last seven years.'
"The Druid Figal, the son of Mamos, said, 'I shall make three rains of fire fall on the faces of the Fomorian warriors; I shall take from them two-thirds of their valour and courage, but so often as the warriors of the De Danann shall breathe out the air from their breasts, so often shall they feel their courage and valour and strength increase. Even though the war should last seven years it shall not fatigue them.'
"The Dagda answered, 'All the feats which you three, sorcerer, cup-bearer, druid, say you can do, I myself alone shall do them.'
"'It is you then are the Dagda,'[10] said those present, whence came the name of the Dagda which he afterwards bore."
Lugh then went in search of the three gods of Dana—Brian, Iuchar, and Iucharba (whom he afterwards put to death for slaying his father, as is recorded at length in the saga of the "Fate of the Children of Tuireann"[11]) and with these and his other allies he spent the next seven years in making preparations for the great struggle with the Fomorians.
This saga and the whole story of the Tuatha De Danann contending with the Fomorians, who are in one place in the saga actually called sidhe, or spirits, is all obviously mythological, and has usually been explained, by D'Arbois de Jubainville and others, as the struggle between the gods or good spirits and the evil deities.
The following episode also shows the wild mythological character of the whole.
"Dagda," says the saga, "had a habitation at Glenn-Etin in the north. He had arranged to meet a woman at Glenn-Etin on the day of Samhan [November day] just a year, day for day, before the battle of Moytura. The Unius, a river of Connacht, flows close beside Glenn-Etin, to the south. Dagda saw the woman bathe herself in the Unius at [Kesh] Coran. One of the woman's feet in the water touched Allod Eche, that is to say Echumech to the south, the other foot also in the water touched Lescuin in the north. Nine tresses floated loose around her head. Dagda approached and accosted her. From thenceforth the place has been named the Couple's Bed. The woman was the goddess Mór-rígu"—
