But the keeper replied, "If thou be Rustem, mount him, and retrieve the sorrows of Iran. For his price is the land of Iran, and seated upon him thou wilt save the world."
And Rustem rejoiced in Rakush (whose name, being interpreted, meaneth the lightning), and Zal rejoiced with him, and they made them ready to stand against Afrasiyab.
Now it was in the time of roses, and the meadows smiled with verdure, when Zal led forth his hosts against the offspring of Tur. And the standard of Kawah streamed upon the breeze, and Mihrab marched on the left, and Gustahem marched on the right, and Zal went in the midst of the men, but Rustem went at the head of all. And there followed after him a number like to the sands of the sea, and the sounds of cymbals and bells made a noise throughout the land like unto the day of judgment, when the earth shall cry unto the dead, "Arise." And they marched in order even unto the shores of the river Rai, and the two armies were but some farsangs apart.
Albeit, when Afrasiyab heard that Rustem and Zal were come out against him, he was in nowise dismayed, for he said, "The son is but a boy, and the father is old; it will not, therefore, be hard for me to keep my power in Iran." And he made ready his warriors with gladness of heart.
But Zal, when he had drawn up his army in battle array, spake unto them, saying-"O men valiant in fight, we are great in number, but there is wanting to us a chief, for we are without the counsels of a Shah, and verily no labour succeedeth when the head is lacking. But rejoice, and be not downcast in your hearts, for a Mubid hath revealed unto me that there yet liveth one of the race of Feridoun to whom pertaineth the throne, and that he is a youth wise and brave."
And when he had thus spoken, he turned him to Rustem and said-"I charge thee, O my son, depart in haste for the Mount Alberz, neither tarry by the way. And wend thee unto Kai Kobad, and say unto him that his army awaiteth him, and that the throne of the Kaianides is empty."
And Rustem, when he had heard his father's command, touched with his eyelashes the ground before his feet, and straightway departed. In his hand he bare a mace of might, and under him was Rakush the swift of foot. And he rode till he came within sight of the Mount Alberz, whereon had stood the cradle of his father. Then he beheld at its foot a house beauteous like unto that of a king. And around it was spread a garden whence came the sounds of running waters, and trees of tall stature uprose therein, and under their shade, by a gurgling rill, there stood a throne, and a youth, fair like to the moon, was seated thereon. And round about him leaned knights girt with red sashes of power, and you would have said it was a paradise for perfume and beauty.
Now when those within the garden beheld the son of Zal ride by, they came out unto him and said-"O Pehliva, it behoveth us not to let thee go farther before thou hast permitted us to greet thee as our guest. We pray thee, therefore, descend from off thy horse and drink the cup of friendship in our house."
But Rustem said, "Not so, I thank you, but suffer that I may pass unto the mountain with an errand that brooketh no delay. For the borders of Iran are encircled by the enemy, and the throne is empty of a king.
Wherefore I may not stay to taste of wine."
Then they answered him, "If thou goest unto the mount, tell us, we pray thee, thy mission, for unto us is it given to guard its sides."
And Rustem replied, "I seek there a king of the seed of Feridoun, who cleansed the world of the abominations of Zohak, a youth who reareth high his head. I pray ye, therefore, if ye know aught of Kai Kobad, that ye give me tidings where I may find him."
Then the youth that sat upon the throne opened his mouth and said, "Kai Kobad is known unto me, and if thou wilt enter this garden and rejoice my soul with thy presence I will give thee tidings concerning him."
When Rustem heard these words he sprang from off his horse and came within the gates. And the youth took his hand and led him unto the steps of the throne. Then he mounted it yet again, and when he had filled a cup with wine, he pledged the guest within his gates. Then he gave a cup unto Rustem, and questioned him wherefore he sought for Kai Kobad, and at whose desire he was come forth to find him.
And Rustem told him of the Mubids, and how that his father had sent him with all speed to pray the young King that he would be their Shah, and lead the host against the enemies of Iran. Then the youth, when he had listened to an end, smiled and said-"O Pehliva, behold me, for verily I am Kai Kobad of the race of Feridoun!"
And Rustem, when he had heard these words, fell on the ground before his feet, and saluted him Shah. Then the King raised him, and commanded that the slaves should give him yet another cup of wine, and he bore it to his lips in honour of Rustem, the son of Zal, the son of Saum, the son of Neriman. And they gave a cup also unto Rustem, and he cried-"May the Shah live for ever!"
Then instruments of music rent the air, and joy spread over all the assembly. But when silence was fallen yet again, Kai Kobad opened his mouth and said-"Hearken, O my knights, unto the dream that I had dreamed, and ye will know wherefore I called upon you this day to stand in majesty about my throne. For in my sleep I beheld two falcons white of wing, and they came out unto me from Iran, and in their beaks they bare a sunny crown. And the crown they placed upon my head. And behold now is Rustem come out unto me like to a white bird, and his father, the nursling of a bird, hath sent him, and they have given unto me the crown of Iran."
And Rustem, when he had heard this dream, said, "Surely thy vision was given unto thee of God! But now, I pray thee, up and tarry no longer, for the land of Iran groaneth sore and awaiteth thee with much travail."
