Diuk's eyes had gleamed as his mother spoke of the way in which his ancestors had won their wealth; and seeing this she tried another course. "Besides," she went on quickly, "there are three great barriers on the way to Kiev city. The first is the barrier of the moving mountains, which clash together and catch the unwary traveller in their strong grip. The second is the barrier of the ravenous birds, which will tear thee and thy good steed to a thousand pieces. The third barrier is the Mountain Dragon with twelve tails, each with a sting in it. He will devour you if indeed you have been fortunate enough to pass the clashing mountains and the ravenous birds." Each fresh terror which she described added to the young man's eagerness to set out upon the journey to Kiev town; and having done reverence to his weeping mother he went to the stable and combed the coat of his faithful steed with a fine comb of fishes' teeth, as well as the mane and tail, which brushed the bosom of moist Mother Earth as he passed on his flight and swept away all traces of his hoofs. Then he saddled his good horse and plaited bright jewels in his mane, standing off to admire his handiwork, speaking meanwhile to the animal in human speech; and in human speech the horse replied to him saying: "Tear not my sides with spurs, dear master; lash me not with your whip of silk; tighten not the bridle upon my faithful head; but when I speed cling to my mane and fear not when I leap from mountain-top to mountain-top, when I clear a great lake at a bound and a river at an easy jump. So shall I be your friend and helper as was Cloudfall to Ilya of Murom the Old Cossáck." Then Diuk prepared himself for the heroic journey and went to say farewell to his lady mother, who had wept till her eyes were bright again, and she was ready to give both leave and blessing to her bold and fearless son. She gave him also a warning. "My dear son," she said, "when you come to Kiev town and to the Court of Prince Vladimir and he makes a banquet in your honour, boast not of your wealth, or of me your mother." Then she kissed him upon his honey mouth and he rode away with happy heart. They saw him as he mounted Rough-Coat but they did not see him as he rode, so swift was his flight--it was only a wreath of smoke, a pillar of dust far off upon the boundless plain, and he was gone.
