"Thou shalt have horses of the fairy breed,
Thou shalt have hounds that can outrun the wind;
A hundred chiefs shall follow thee in war,
A hundred maidens sing thee to thy sleep.
"A crown of sovranty thy brow shall wear,
And by thy side a magic blade shall hang.
Thou shalt be lord of all the Land of Youth,
And lord of Niam of the Head of Gold."
As the magic song ended, the Fians beheld Oisín mount the fairy steed and hold the maiden in his arms, and ere they could stir or speak she turned her horse's head and shook the ringing bridle and down the forest glade they fled, as a beam of light flies over the land when clouds drive across the sun; and never did the Fianna behold Oisín, son of Finn, on earth again.
Yet what befell him afterwards is known. As his birth was strange so was his end, for he saw the wonders of the Land of Youth with mortal eyes and lived to tell them with mortal lips.
When the white horse with its riders reached the sea it ran lightly over the waves and soon the green woods and headlands of Erinn faded out of sight. And now the sun shone fiercely down, and the riders passed into a golden haze in which Oisín lost all knowledge of where he was or if sea or dry land were beneath his horse's hoofs. But strange sights sometimes appeared to them in the mist, for towers and palace gateways loomed up and disappeared, and once a hornless doe bounded by them chased by a white hound with one red ear, and again they saw a young maid ride by on a brown steed, bearing a golden apple in her hand, and close behind her followed a young horseman on a white steed, a purple cloak floating at his back and a gold-hilted sword in his hand. And Oisín would have asked the princess who and what these apparitions were, but Niam bade him ask nothing nor seem to notice any phantom they might see until they were come to the Land of Youth.
At last the sky gloomed above them, and Niam urged their steed faster. The wind lashed them with pelting rain, thunder roared across the sea and lightning blazed, but they held on their way till at length they came once more into a region of calm and sunshine. And now Oisín saw before him a shore of yellow sand, lapped by the ripples of a summer sea. Inland, there rose before his eye wooded hills amid which he could discern the roofs and towers of a noble city. The white horse bore them swiftly to the shore and Oisín and the maiden lighted down. And Oisín marvelled at everything around him, for never was water so blue or trees so stately as those he saw, and the forest was alive with the hum of bees and the song of birds, and the creatures that are wild in other lands, the deer and the red squirrel and the wood-dove, came, without fear, to be caressed. Soon, as they went forward, the walls of a city came in sight, and folk began to meet them on the road, some riding, some afoot, all of whom were either youths or maidens, all looking as joyous as if the morning of happy life had just begun for them, and no old or feeble person was to be seen. Niam led her companion through a towered gateway built of white and red marble, and there they were met by a glittering company of a hundred riders on black steeds and a hundred on white, and Oisín mounted a black horse and Niam her white, and they rode up to a stately palace where the King of the Land of Youth had his dwelling. And there he received them, saying in a loud voice that all the folk could hear, "Welcome, Oisín, son of Finn. Thou art come to the Land of Youth, where sorrow and weariness and death shall never touch thee. This thou hast won by thy faithfulness and valour and by the songs that thou hast made for the men of Erinn, whereof the fame is come to us, for we have here indeed all things that are delightful and joyous, but poesy alone we had not. But now we have the chief poet of the race of men to live with us, immortal among immortals, and the fair and cloudless life that we lead here shall be praised in verses as fair; even as thou, Oisín, did'st praise and adorn the short and toilsome and chequered life that men live in the world thou hast left forever. And Niam my daughter shall be thy bride, and thou shalt be in all things even as myself in the Land of Youth."
Then the heart of Oisín was filled with glory and joy, and he turned to Niam and saw her eyes burn with love as she gazed upon him. And they were wedded the same day, and the joy they had in each other grew sweeter and deeper with every day that passed. All that Niam had promised in her magic song in the wild wood when first they met, seemed faint beside the splendour and beauty of the life in the Land of Youth. In the great palace they trod on silken carpets and ate off plates of gold; the marble walls and doorways were wrought with carved work, or hung with tapestries, where forest glades, and still lakes, and flying deer were done in colours of unfading glow. Sunshine bathed that palace always, and cool winds wandered through its dim corridors, and in its courts there played fountains of bright water set about with flowers. When Oisín wished to ride, a steed of fiery but gentle temper bore him wherever he would through the pleasant land; when he longed to hear music, there came upon his thought, as though borne on the wind, crystal notes such as no hand ever struck from the strings of any harp on earth.
But Oisín's hand now never touched the harp, and the desire of singing and of making poetry never waked in him, for no one thing seemed so much better than the rest, where all perfection bloomed and glowed around him, as to make him long to praise it and to set it apart.
