This sight only increased the misery of the Prince, for he did not know where the castle was, nor how to set about finding it. However, he resolved to seek the whole world through till he came to the right place. He began by setting sail in a favourable wind, but his bad luck followed him even on the sea. He had scarcely lost sight of the land when a violent storm arose, and after several hours of beating about, the vessel was driven on to some rocks, on which it dashed itself to bits. The Prince was fortunate enough to be able to lay hold of a floating spar, and contrived to keep himself afloat; and, after a long struggle with the winds and waves, he was cast upon a strange island. But what was his surprise, on reaching the shore, to hear sounds of the most heartrending distress, mingled with the sweetest songs which had ever charmed him! His curiosity was instantly roused, and he advanced cautiously till he saw two huge dragons guarding the gate of a wood. They were terrible indeed to look upon. Their bodies were covered with glittering scales; their curly tails extended far over the land; flames darted from their mouths and noses, and their eyes would have made the bravest shudder; but as the Prince was invisible and they did not see him, he slipped past them into the wood. He found himself at once in a labyrinth, and wandered about for a long time without meeting anyone; in fact, the only sight he saw was a circle of human hands, sticking out of the ground above the wrist, each with a bracelet of gold, on which a name was written. The farther he advanced in the labyrinth the more curious he became, till he was stopped by two corpses lying in the midst of a cypress alley, each with a scarlet cord round his neck and a bracelet on his arm on which were engraved their own names, and those of two Princesses.
The invisible Prince recognised these dead men as Kings of two large islands near his own home, but the names of the Princesses were unknown to him. He grieved for their unhappy fate, and at once proceeded to bury them; but no sooner had he laid them in their graves, than their hands started up through the earth and remained sticking up like those of their fellows.
The Prince went on his way, thinking about this strange adventure, when suddenly at the turn of the walk he perceived a tall man whose face was the picture of misery, holding in his hands a silken cord of the exact colour of those round the necks of the dead men. A few steps further this man came up with another as miserable to the full as he himself; they silently embraced, and then without a word passed the cords round their throats, and fell dead side by side. In vain the Prince rushed to their assistance and strove to undo the cord. He could not loosen it; so he buried them like the others and continued his path.
He felt, however, that great prudence was necessary, or he himself might become the victim of some enchantment; and he was thankful to slip past the dragons, and enter a beautiful park, with clear streams and sweet flowers, and a crowd of men and maidens. But he could not forget the terrible things he had seen, and hoped eagerly for a clue to the mystery. Noticing two young people talking together, he drew near thinking that he might get some explanation of what puzzled him. And so he did.
'You swear,' said the Prince, 'that you will love me till you die, but I fear your faithless heart, and I feel that I shall soon have to seek the Fairy Despair, ruler of half this island. She carries off the lovers who have been cast away by their mistresses, and wish to have done with life. She places them in a labyrinth where they are condemned to walk for ever, with a bracelet on their arms and a cord round their necks, unless they meet another as miserable as themselves. Then the cord is pulled and they lie where they fall, till they are buried by the first passer-by. Terrible as this death would be,' added the Prince, 'it would be sweeter than life if I had lost your love.'
The sight of all these happy lovers only made the Prince grieve the more, and he wandered along the seashore spending his days; but 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.
