The other infant was seized by Gwydion and brought up under his protection. Like other solar heroes, he grew very rapidly; when he was four he was as big as if he were eight, and the comeliest youth that ever was seen. One day Gwydion took him to visit his mother Arianrod. She hated the children who had exposed her false pretensions, and upbraided Gwydion for bringing the boy into her sight. “What is his name?” she asked. “Verily,” said Gwydion, “he has not yet a name.” “Then I lay this destiny upon him,” said Arianrod, “that he shall never have a name till one is given him by me.” On this Gwydion went forth in wrath, and remained in his castle of Caer Dathyl that night.
Though the fact does not appear in this tale, it must be remembered that Gwydion is, in the older mythology, the father of Arianrod’s children.
He was resolved to have a name for his son. Next day he went to the strand below Caer Arianrod, bringing the boy with him. Here he sat down by the beach, and in his character of a master of magic he made himself look like a shoemaker, and the boy like an apprentice, and he began to make shoes out of sedges and seaweed, to which he gave the semblance of Cordovan leather. Word was brought to Arianrod of the wonderful shoes that were being made by a strange cobbler, and she sent her measure for a pair. Gwydion made them too large. She sent it again, and he made them too small. Then she came herself to be fitted. While this was going on, a wren came and lit on the boat’s mast, and the boy, taking up a bow, shot an arrow that transfixed the leg between the sinew and the bone. Arianrod admired the brilliant shot. “Verily,” she said, “with a steady hand (_llaw gyffes_) did the lion (_llew_) hit it.” “No thanks to thee,” cried Gwydion, “now he has got a name. Llew Llaw Gyffes shall he be called henceforward.”
We have seen that the name really means the same thing as the Gaelic Lugh Lamfada, Lugh (Light) of the Long Arm; so that we have here an instance of a legend growing up round a misunderstood name inherited from a half-forgotten mythology.
The shoes went back immediately to sedges and seaweed again, and Arianrod, angry at being tricked, laid a new curse on the boy. “He shall never bear arms till I invest him with them.” But Gwydion, going to Caer Arianrod with the boy in the semblance of two bards, makes by magic art the illusion of a foray of armed men round the castle. Arianrod gives them weapons to help in the defence, and thus again finds herself tricked by the superior craft of Gwydion.
