She began to make the shirt and worked without stopping till it was finished. Then she went on her journey and never rested till she came to Erin in a ship. She went on shore and inquired where Fin and his men were to be found at that time of the year.
"You will find them at Knock an Ar," was the answer she got.
She went to Knock an Ar carrying the shirt with her. The first man she met was Conan Maol, and she said to him: "I have come to find the man this shirt will fit. From the time one man tries it all must try till I see the man it fits."
The shirt went from hand to hand till Cucúlin put it on. "Well," said she, "it fits as your own skin."
Now Gil an Og told Cucúlin all that had happened,—how her father had forced her sister to marry the king of Greece, how this king had made war on her father, enchanted her sister and herself, and carried off the rod of enchantment with the ring of youth, and how the old Druid said the man this shirt would fit was the only man in the world who could release them.
Now Gil an Og and Cucúlin went to the ship and sailed across the seas to her country and went to her castle.
"You'll have no one but a cat for company to-night," said Gil an Og. "I have the form of a cat inside this castle, but outside I have my own appearance. Your dinner is ready, go in."
After the dinner Cucúlin went to another room apart, and lay down to rest after the journey. The cat came to his pillow, sat there and purred till he fell asleep and slept soundly till morning.
When he rose up, a basin of water, and everything he needed was before him, and his breakfast ready. He walked out after breakfast; Gil an Og was on the green outside before him and said:
"If you are not willing to free my sister and myself, I shall not urge you; but if you do free us, I shall be glad and thankful. Many king's sons and champions before you have gone to recover the ring and the rod; but they have never come back."
"Well, whether I thrive or not, I'll venture," said Cucúlin.
