“Not one of us has crossed that bridge,” said Ferdia, “for there are two feats that Skatha teaches last, and one is the leap across the bridge, and the other the thrust of the Gae Bolg.(139) For if a man step upon one end of that bridge, the middle straightway rises up and flings him back, and if he leap upon it he may chance to miss his footing and fall into the gulf, where the sea-monsters are waiting for him.” But Cuchulain waited till evening, when he had recovered his strength from his long journey, and then essayed the crossing of the bridge. Three times he ran towards it from a distance, gathering all his powers together, and strove to leap upon the middle, but three times it rose against him and flung him back, while his companions jeered at him because he would not wait for the help of Skatha. But at the fourth leap he lit fairly on the centre of the bridge, and with one leap more he was across it, and stood before the strong fortress of Skatha; and she wondered at his courage and vigour, and admitted him to be her pupil. For a year and a day Cuchulain abode with Skatha, and all the feats she had to teach he learned easily, and last of all she taught him the use of the Gae Bolg, and gave him that dreadful weapon, which she had deemed no champion before him good enough to have. And the manner of using the Gae Bolg was that it was thrown with the foot, and if it entered an enemy’s body it filled every limb and crevice of him with its barbs. While Cuchulain dwelt with Skatha his friend above all friends and his rival in skill and valour was Ferdia, and ere they parted they vowed to love and help one another as long as they should live. *Cuchulain and Aifa* Now whilst Cuchulain was in the Land of the Shadows it chanced that Skatha made war on the people of the Princess Aifa, who was the fiercest and strongest of the woman-warriors of the world, so that even Skatha feared to meet her in arms. On going forth to the war, therefore, Skatha mixed with Cuchulain’s drink a sleepy herb so that he should not wake for four-and-twenty hours, by which time the host would be far on its way, for she feared lest evil should come to him ere he had got his full strength. But the potion that would have served another man for a day and a night only held Cuchulain for one hour; and when he waked up he seized his arms and followed the host by its chariot-tracks till he came up with them. Then it is said that Skatha uttered a sigh, for she knew that he would not be restrained from the war.
