The instant the ladies round Cuchulain heard it they also shouted, and the musicians struck up—but in vain; Cuchulain had caught the sound. They succeeded, however, in calming his mind, and in inducing him to pay no heed to the false witcheries of the clan Calatin. These continued for a long time waiting and filling the air with their unreal battle tumult, but Cuchulain did not appear. Then they understood that the druids had been more powerful than they. Mad with impotent fury one of them enters the glen, and pushes her way right into the very fortress where Cuchulain was feasting. Once there she changes herself into the form of the beautiful Niamh [Nee-av], Cuchulain's love and sweetheart. First she stood at the door in the likeness of an attendant damsel, and beckoned to the lady to come to her outside. Niamh, thinking she has something to communicate, follows her through the door and out into the valley, and the other ladies follow Niamh. Instantly she raises an enchanted fog between them and the dún, so that they wander astray, and their minds are troubled. But she, assuming the form of the lady Niamh herself, slips back into the fortress, comes to Cuchulain, and cries to him: "Up, O Cuchulain, and meet the men of Erin, or thy fame shall be lost for ever, and the province shall be destroyed." At this speech Cuchulain is astounded, for Niamh had bound him by an oath that he would not go forth or take arms until she herself should give him leave, and this leave he never thought to receive of her until the fatal time was over. "I shall go," said Cuchulain, "and that is a pity, O Niamh," said he, "and after that it is difficult to trust to woman, for I had thought thou hadst not given me that leave for the gold of the world, but since it is thou who dost let me go to face the men of Erin, I shall go." After that he rose and left the dún. "I have no reason for preserving my life longer," said Cuchulain, "for the end of my time is come, and all my geasa (tabus) are lost, and Niamh has let me go to face the men of Erin; and since she has let me, I shall go."

Afterwards the real Niamh overtakes him at the entrance to the glen, and assured him with torrents of tears, and wild sobs, that it was not she who had given him leave, but the vile enchantress who had assumed her form, and she conjured him with prayers and piteous entreaties to remain with her. But Cuchulain would not believe her, and urged Laeg to catch his steeds and yoke them, for he thought that he beheld—

"The great battle-battalions ranged upon the green of Emania, and the whole plain filled up and crowded with broad bands of hundreds of men, with champions, and steeds, and arms, and armour, and he thought he heard the awful shoutings, and [saw] the burnings extending, widely-let-loose through the buildings of Conor's city, and him-seemed that there was nor hill nor rising ground about Emania that was not full of spoils, and it appeared to him that Emer's sunny-house was overthrown and had fallen out over the ramparts of Emania, and that the House of the Red Branch was in one blaze, and that all Emania was one meeting-place of fire, and of black, dark, spacious, brown-red smoke."[9]

Then Cuchulain's brooch fell from his hand and pierced his foot, another omen of ill. Nor would his noble grey war-horse allow himself to be caught. It was only when Cuchulain addressed him with persuasive words of verse that he consented to let himself be harnessed to the chariot, and even then "he lets fall upon his fore feet, from his eyes, two large tears of blood." In vain did the ladies of Emania try to bar his passage, in vain did fifty queens uncover their bosoms before him in supplication. "He is the first," says the saga, "of whom it is recounted that women uncovered before him their bosoms."[10]

Thereafter another evil omen overtook him, for as he pursued the high road leading to the south,

"and had passed the plain of Mogna, he perceived something, three hags of the half-blind race,[11] who were on the track before him cooking a poisoned dog's flesh upon spits of holly. Now it was a geis (tabu) to Cuchulain to pass a cooking-fire without visiting it and accepting food. It was another geis to eat of his own name" [i.e., a hound, he is Cu-Chulain or Culan's hound], "so he pauses not, but passes the three hags. Then one of them cries to him—

"'Come, visit us, Cuchulain.'

"'I shall not visit you,' said Cuchulain.

"'There is something to eat here,' replied the hag; 'we have a dog to offer thee. If our cooking-place were great,' said she, 'thou wouldst come, but because it is small thou comest not; a great man who despises the small, deserves no honour.'

"Cuchulain then moved over to the hag, and she with her left hand offered him half the dog. Cuchulain ate, and it was with his left hand he took the piece, and he placed part of it under his left thigh, and his left hand and his left thigh were cursed, and the curse reached all his left side, which from his head to his feet lost a great part of its power."

At last Cuchulain meets the enemy on his ancestral patrimony of Moy Muirtheimhne, drawn up in battle array, with shield to shield as though it were one solid plank that was around them. Cuchulain displays his feats from his chariot, especially "his three thunder-feats—the thunder of an hundred, the thunder of three hundred, the thunder of thrice nine men."

"He played equally with spear, shield, and sword, he performed all the feats of a warrior. As many as there are of grains of sand in the sea, of stars in the heaven, of dewdrops in May, of snowflakes in winter, of hailstones in a storm, of leaves in a forest, of ears of corn in the plains of Bregia, of sods beneath the feet of the steeds of Erin on a summer's day, so many halves of heads, and halves of shields, and halves of hands and halves of feet, so many red bones were scattered by him throughout the plain of Muirtheimhne, it became grey with the brains of his enemies, so fierce and furious was Cuchulain's onslaught."

The plan which Erc, son of the late High-king Cairbré Niafer had adopted was to place two men pretending to fight with one another upon each flank of the army and a druid standing near who should first make Cuchulain separate the combatants, and should then demand from him his spear, since there ran a prophecy to the effect that Cuchulain's spear should kill a king, but if they could get the spear from him they at least would be safe from the prophecy; it would not be one of them who should be slain by it.
