There was great feasting and rejoicing when, later, their nuptials were solemnized, and after the wedding the prince remained within the palace and lived in peace.
Now one day the queen went for a walk in the palace grounds accompanied by an attendant, the prince remaining in the palace. Before starting the queen gave her spouse the keys of twelve cellars, saying: "You may go into the cellars, all but one; do not on any account go into the twelfth; you must not even open the door!"
The prince soon began to speculate upon what there could possibly be in the twelfth cellar; and having opened one cellar after the other, he stood hesitatingly at the door of the twelfth. He who hesitates is lost, and so the prince finally inserted the key in the lock and the next moment had passed into the forbidden place. In the middle of the floor was a huge cask bound tightly round with three strong iron hoops. The bung-hole was open and from within the cask came a muffled voice which said: "I pray thee, brother, give me a drink of water, else I shall die of thirst!" The prince took a glass of water and poured it through the bung-hole; immediately one hoop burst. Then the voice spake again: "O brother give me more water lest I should die of thirst!" The good-hearted prince emptied a second glass into the cask, and a second hoop instantly came asunder. Again the voice implored: "O brother, give me yet a third glass! I am still consumed by thirst!" The prince made haste to gratify the unseen speaker, and as he poured in the water the third hoop burst, the cask fell in pieces, and a great dragon struggled out from the wreck, rushed through the door and flew into the open. Very soon he fell in with the queen, who was on her way back to the palace, and carried her off. Her attendant, affrighted, rushed to the prince with the intelligence, and the news came as a thunderbolt.
For a time the prince was as one distraught, but then he became more calm and he resolved to set out again in search of his beloved queen. In his wanderings he came to a river, and, walking along its bank, he noticed in a little hole a small fish leaping and struggling. When the fish saw the prince it began to beseech him piteously: "Be my brother-in-God! Throw me back into the stream; some day I may, perhaps, be useful to you! But be sure to take a scale from me, and when you are in need of help rub it gently." The prince picked up the fish, took a scale from it, and threw the poor creature into the water; then he carefully wrapped the scale in his handkerchief.
