When they entered the town, Raksh neighed. His voice was as loud as thunder, and the King heard it, and in a moment understood all that had happened. “That is the voice of Raksh,” he said to the Persians that were with him; “our evil days are over. This was the way in which he neighed in King Kobad’s time, when he made war on the Scythians.”
The Persians said to themselves, “Our poor King has lost his senses, or he is dreaming. There is no help for us.” But they had hardly finished speaking when the hero appeared, and did homage to the King. Kaoues embraced him, and then said: “If you are to help me, you must go before the Genii know of your coming. So soon as the White Genius shall hear of the fall of Arzeng, he will assemble such an army of his fellows as shall make all your pains and labor lost. But you must know that you have great difficulties to overcome.

Aulad answered, “When the sun shall grow hot, the Genii will go to sleep. That will be your time to conquer them.”
Rustem waited till the sun was at its highest, and then went forth to battle. The Genii that were on guard fled at the sound of his voice, and he went on without finding any to resist him till he came to the great cavern of which the King had spoken. It was a terrible place to see, and he stood for a while with his sword in his hand, doubting what he should do. No one would choose such a spot for battle; and as for escaping from it, that was beyond all hope. Long he looked into the darkness, and at last he saw a monstrous shape, which seemed to reach across the whole breadth of the cave. It was the White Genius that was lying asleep. Rustem did not attempt to surprise him in his sleep, but
