The sight of all these happy lovers only made the Prince grieve the more, and he wandered along the seashore spending his days; b ut one day he was sitting on a rock bewailing his fate, and the impossibility of leaving the island, when all in a moment the sea appeared to raise itself nearly to the skies, and the caves echoed with hideous screams. As he looked a woman rose from the depths of the sea, flying madly before a furious giant. The cries she uttered softened the heart of the Prince; he took the stone from his mouth, and drawing his sword he rushed after the giant, so as to give the lady time to escape. But hardly had he come within reach of the enemy, than the giant touched him with a ring that he held in his hand, and the Prince remained immovable where he stood. The giant then hastily rejoined his prey, and, seizing her in his arms, he plunged her into the sea. Then he sent some tritons to bind chains about the Prince of the Golden Isle, and he too felt himself borne to the depths of the ocean, and without the hope of ever again seeing the Princess.
Now the giant whom the invisible had so rashly attacked was the Lord of the Sea, and the third son of the Queen of the Elements, and he had touched the youth with a magic ring which enabled a mortal to live under water. So the Prince of the Golden Isle found, when bound in chains by the tritons, he was carried through the homes of strange monsters and past immense seaweed forests, till he reached a vast sandy space, surrounded by huge rocks. On the tallest of the rocks sat the giant as on a throne.
'Rash mortal,' said he, when the Prince was dragged before him, 'you have deserved death, but you shall live only to suffer more cruelly. Go, and add to the number of those whom it is my pleasure to torture.'
At these words the unhappy Prince found himself tied to a rock; but he was not alone in his misfortunes, for all round him were chained Princes and Princesses, whom the giant had led captive.
Indeed, it was his chief delight to create a storm, in order to add to the list of his prisoners.
As his hands were fastened, it was impossible for the Prince of the Golden Isle to make use of his magic stone, and he passed his nights and days dreaming of Rosalie. But at last the time came when the giant took it into his head to amuse himself by arranging fights between some of his captives. Lots were drawn, and one fell upon our Prince, whose chains were immediately loosened. The moment he was set free, he snatched up his stone, and became invisible.
The astonishment of the giant at the sudden disappearance of the Prince may well be imagined. He ordered all the passages to be watched, but it was too late, for the Prince had already glided between two rocks. He wandered for a long while through the forests, where he met nothing but fearful monsters; he climbed rock after rock, steered his way from tree to tree, till at length he arrived at the edge of the sea, at the foot of a mountain that he remembered to have seen in the cabinet of the present, where Rosalie was held captive.
Filled with joy, he made his way to the top of the mountain which pierced the clouds, and there he found a palace. He entered, and in the middle of a long gallery he discovered a crystal room, in the midst of which sat Rosalie, guarded night and day by genii.
There was no door anywhere, nor any window. At this sight the Prince became more puzzled than ever, for he did not know how he was to warn Rosalie of his return. Yet it broke his heart to see her weeping from dawn till dark.
One day, as Rosalie was walking up and down her room, she was surprised to see that the crystal which served for a wall had grown cloudy, as if some one had breathed on it, and, what was more, wherever she moved the brightness of the crystal always became clouded. This was enough to cause the Princess to suspect that her lover had returned. In order to set the Prince of the Air's mind at rest she began by being very gracious to him, so that when she begged that her captivity might be a little lightened she should not be refused. At first the only favour she asked was to be allowed to walk for one hour every day up and down the long gallery. This was granted, and the Invisible Prince speedily took the opportunity of handing her the stone, which she at once slipped into her mouth. No words can paint the fury of her captor at her disappearance. He ordered the spirits of the air to fly through all space, and to bring back Rosalie wherever she might be. They instantly flew off to obey his commands, and spread themselves over the whole earth.
Meantime Rosalie and the Invisible Prince had reached, hand in hand, a door of the gallery which led through a terrace into the gardens. In silence they glided along, and thought themselves already safe, when a furious monster dashed itself by accident against Rosalie and the Invisible Prince, and in her fright she let go his hand. No one can speak as long as he is invisible, and besides, they knew that the spirits were all around them, and at the slightest sound they would be recognised; so all they could do was to feel about in the hope that their hands might once more meet.
