After a somewhat lengthy journey the Prince and the wolf came to the kingdom ruled over by the Emperor who possessed the golden horse. One evening late they reached the capital, and the wolf advised the Prince to set to work at once, before their presence in the city had aroused the watchfulness of the guards. They slipped unnoticed into the Emperor’s stables and into the very place where there were the most guards, for there the wolf rightly surmised they would find the horse. When they came to a certain inner door the wolf told the Prince to remain outside, while he went in. In a short time he returned and said, ‘My dear Prince, the horse is most securely watched, but I have bewitched all the guards, and if you will only be careful not to touch the wall yourself, or let the horse touch it as you go out, there is no danger and the game is yours. The Prince, who had made up his mind to be more than cautious this time, went cheerfully to work. He found all the guards fast asleep, and, slipping into the horse’s stall, he seized it by the bridle and led it out; but, unfortunately, before they had got quite clear of the stables a gadfly stung the horse and caused it to switch its tail, whereby it touched the wall. In a moment all the guards awoke, seized the Prince and beat him mercilessly with their horse-whips, after which they bound him with chains, and flung him into a dungeon. Next morning they brought him before the Emperor, who treated him exactly as the King with the golden bird had done, and commanded him to be beheaded on the following day. When the wolf-magician saw that the Prince had failed this time too, he transformed himself again into a mighty king, and proceeded with an even more gorgeous retinue than the first time to the Court of the Emperor. He was courteously received and entertained, and once more after dinner he led the conversation on to the subject of slaves, and in the course of it again requested to be allowed to see the bold robber who had dared to break into the Emperor’s stable to steal his most valuable possession. The Emperor consented, and all happened exactly as it had done at the court of the Emperor with the golden bird; the prisoner’s life was to be spared only on condition that within three days he should obtain possession of the golden mermaid, whom hitherto no mortal had ever approached.
