Suddenly a voice cried, "Open the door, ye princes!"

Up spoke the Emperor's eldest son, "Do not open!" And the second said, "On no account open!" But the youngest said, "Then I will open the door myself."

He sprang up and drew the bolts. Hardly was the door opened when a fearful Being rushed in, the outline of whose form was hidden in encircling flames.

"I am come," he exclaimed, "to take your eldest sister for my wife, and that at once. So give a short answer—yes or no; I insist upon it!"

Said the eldest brother, "I will not give her to you. Why should I, when I know neither who nor whence you are? You come here by night, demand my sister's hand upon the instant, and I do not even hear which way I am to turn when I wish to visit her."

Said the second brother, "Nor do I permit you to take away my sister thus in the dead of night."

But the youngest interposed, "Then I will give her away if you two refuse. Have you already forgotten our father's command?" And taking his sister by the hand he gave her to the stranger, saying, "May she live happily with you and be ever faithful!"

As the sister crossed the threshold every one in the building fell to the ground in fear and horror. It lightened, it thundered, it crashed, it quaked, the whole fortress swayed heavily, as if heaven and earth were falling together. Gradually the uproar died away, and the rosy eastern light announced the coming morning.

As soon as day had broken the brothers searched for the traces which they supposed would have been left by their tremendous nocturnal visitor; but not a trace, not a footprint had he left behind. All was swept away.
