He rowed all round the shores, beating the sedges with his oar, in pursuit of the swan; but all in vain; he could not catch a glimpse of her white plumage anywhere. Day after day he rowed about the lake in search of her, and every evening he lay outside the hut watching the waters. At long last, one night, when the full moon, rising above the mountains, flooded the whole lake with light, he saw the swan coming swiftly towards him, shining brighter than the moonbeams. The swan came on until it was almost within a boat's length of the hut; and what should Enda hear but the swan speaking to him in his own language:
"Get into your curragh, Enda, and follow me," said she, and, saying this, she turned round and sailed away.
Enda jumped into the curragh, and soon the water, dripping from his oar, was flashing like diamonds in the moonlight. And he rowed after the swan, who glided on before him, until she came to where the shadows of the mountains lay deepest on the lake. Then the swan rested, and when Enda came up to her:
"Enda," said she, "I have brought you where none may hear what I wish to say to you. I am Mave, the daughter of the king of Erin. By the magic arts of my cruel stepmother I was changed into a trout, and cast into this lake a year and a day before the evening when you restored me to the waters the second time. If you had not done so the first night the otter brought me to you I should have been changed into a hooting owl; if you had not done so the second night, I should have been changed into a croaking raven. But, thanks to you, Enda, I am now a snow-white swan, and for one hour on the first night of every full moon the power of speech is and will be given to me as long as I remain a swan. And a swan I must always remain, unless you are willing to break the spell of enchantment that is over me; and you alone can break it."
"I'll do anything I can for you, O princess!" said Enda. "But how can I break the spell?"
"You can do so," said the swan, "only by pouring upon my plumage the perfumed water that fills the golden bowl that is in the inmost room of the palace of the fairy queen, beneath the lake."
"And how can I get that?" said Enda.
"Well," said the swan, "you must dive beneath the lake, and walk along its bed, until you come to where the lake dragon guards the entrance of the fairy queen's dominions."
"I can dive like a fish," said Enda; "but how can I walk beneath the waters?"
"You can do it easily enough," said the swan, "if you get the water-dress of Brian, one of the three sons of Turenn, and his helmet of transparent crystal, by the aid of which he was able to walk under the green salt sea."[3]
