And so Oisin said to Niam, "Let me, for a short while, return to the land of Erinn, that I may see there my friends and kin and tell them of the glory and joy that are mine in the Land of Youth." But Niam wept and laid her white arms about his neck, entreating him to think no more of the sad world where all men live and move under a canopy of death, and where summer is slain by winter, and youth by old age, and where love itself, if it die not by falsehood and wrong, perishes many a time of too complete a joy.

But Oisin said, "The world of men compared with thy world is like this dreary waste compared with the city of thy father; yet in that city, Niam, none is better or worse than another, and I hunger to tell my tale to ignorant and feeble folk that my words can move, as words of mine have done of old, to wonder and delight.

Then I shall return to thee, Niam, and to thy fair and blissful land; and having brought over to mortal men a tale that never man has told before, I shall be happy and at peace for ever in the Land of Youth." So they fared back to the golden city, and next day Niam brought to Oisin the white steed that had borne them from Erinn, and bade him farewell.

"This our steed," she said, "will carry thee across the sea to the land where I found thee, and whithersoever thou wilt, and what folk are there thou shalt see, and what tale thou hast to tell can be told.

But never for even a moment must thou alight from his back, for if thy foot once touch again the soil of earth, thou shalt never win to me and to the Land of Youth again.
