Now it happened that their mother, the princess Briane, had been secretly married to Trebatius, emperor of Constantinople, who had courted her under the name of prince Theodoart. Soon after their marriage her husband, while riding through the forest, had been astonished at the sight of a magnificent chariot which dashed furiously along the road, and, as it passed, he felt sure that his wife, the princess Briane, was seated inside. Without losing a moment, he turned his horse instantly round, and followed the chariot, but, spur his steed as he might, it was impossible to overtake it. However, he rode on as fast as the thick creepers and fallen trees would let him in the direction in which the chariot had disappeared, and at last he left the forest behind him and entered a beautiful meadow.

Here the emperor paused in surprise, for in front of him stood the greatest and finest castle he had ever seen, which would have held thirty thousand men with ease. At each corner was a large tower, while a wide moat of clear water would have kept a large army at bay. Happily for the emperor’s curiosity, the drawbridge was at the moment let down, so he knocked at the door, which straightway opened to him, and boldly entered the castle.

He looked around the magnificent hall to see some traces of his wife, but, instead, a powerful odour stole gradually over his senses. At the same instant a golden curtain was drawn aside, and a lady whose beauty dazzled his eyes glided up to him and laid her hand on his shoulder.

‘You belong to me now,’ she said, as she led him away; and twenty years went by before the emperor again left the castle.

Meanwhile the little boys were carried away in the night by one of the mother’s ladies, whose name was Clandestrie, and taken to her sister’s house, where they lived freely and happily for some years till they were old enough to be brought to the convent where the princess Briane still remained, and taught the duties of pages. Rosiclair was always good and quiet, but his brother gave his teachers a great deal of trouble, though that did not prevent their loving him dearly. He was so tall and strong and high-spirited, that it was difficult to remember he was only a child after all, and the moment he was left alone he was always seeking some adventure.

One day, while Rosiclair was learning from his mother to play on the lute, the Knight of the Sun—for so they called him—had gone with his nurse to the banks of the broad river, and was amusing himself with scrambling in and out of a boat that lay moored to the side. There were no mirrors in the convent, and the boy jumped hastily back with dismay when he saw some one dressed like himself looking at him from out of the water.

He grew red with rage and struck out with his fist, and the arm in the water struck out too. Then the prince sprang forward, but, as he did so, he began to perceive that it was nothing but his own image that was looking at him and imitating his movements. ‘How could I be such a baby!’ he said to himself, and turned to leave the boat, when, to his dismay, he found that the rope had got loose and he was gently floating down the stream.

At this sight his courage began to fail him; he called loudly to his nurse, who had been talking to some friends and had not noticed the child’s danger. At his cries she rushed into the river a little lower down, hoping to catch the boat as it danced by, but the current swept her off her feet, and she would certainly have been drowned had not a wood-cutter, who had watched her from above, held out a long stick which she was able to reach.

Very soon the little boat was a mere speck in the distance, and, now that there was nothing to be done, the boy took heart again and thought of all he would have to tell Rosiclair when he came back—for come back he would some day, he was sure of that.

By-and-by the grass and the trees, and even the big mountains, vanished, and all around him was the blue sea, with not even a sail to look at. How long he remained in that boat he never knew, but one day, just before sunrise, when the air is clearest and you can see farthest, he was roused from his sleep by a shout. At first he took it for part of his dream and did not move; then the shout came again, and he jumped up and waved his hand, for sailing towards him was a large vessel. At the prow stood a man in a beautiful purple tunic edged with gold. This was Florian prince of Persia.
