And while his son Afrasiyab made ready the host to fulfil the desire of his father, there spread the news that Saum the Pehliva had been gathered unto the dust, and that Zal tarried in his house to build him a tomb. And the news gave courage unto Afrasiyab and his men, and they made haste to gain the frontier.
But the grandson of Feridoun had learned of their coming, and he prepared him to meet the foes of his land. Then he sent forth an army that overshadowed the earth in its progress. But the army of Afrasiyab was great also, and it covered the ground like unto ants and locusts.
And both hosts pitched their tents in the plains of Dehstan, and made them ready for the fight. And the horses neighed loud, and the pawing of their hoofs shook the deep places of the earth, and the dust of their trampling uprose even unto heaven. Then when they had put their men into array, they fell upon each other, and for two days did they rage in fierce combat, neither did the victory lean to either side.
And the clamour and confusion were mighty, and earth and sky seemed blended into one. And the carnage was great, and blood flowed like water, and heads fell from their trunks like unto autumn leaves that are withered. But on the third day it came about that the upper hand was given unto the men of Turan, and Nauder the King, and the flower of his army with him, fell into the hands of the foe.
Then Afrasiyab cut off the head of Nauder the Shah, and sat himself down upon the throne of light. And he proclaimed himself lord of Iran, and required of all men that they should do him homage, and pour gifts before his face. But the people would not listen unto his voice, and they sent messengers into Seistan, and craved counsel of the Pehliva in their distress. And Zal, when he heard their tidings, cast aside the sorrow for Saum his father, and girded his loins in enmity against the son of Tur. And he bade the Iranians choose out Zew, the son of Thamasp, of the blood of Feridoun, of wisdom in speech, that he should rule over them on the throne of the Kaianides. And the people did as Zal commanded.
Now the throne of Feridoun grew young again under the sway of Zew.
With power did he beat back the host of Turan, a covenant of peace did he wring from their hands. And it was written that the Jihun should divide the lands, and that the power of Zal the Pehliva should end where men take up their abode in tents. And Zew ruled rightly in the sight of Ormuzd, and God gave unto the land the key of abundance.
Yet few were the years that he commanded with equity, and Garshasp his son reigned in his stead. But neither to him was it given to reign long with glory, and bitter fruit sprouted yet again from the tree of misfortune. For the throne of the Kaianides was empty, and Afrasiyab, when he learned thereof, followed the counsels of Poshang his father, and hurried him unto the land of Iran, that he might place himself upon the seat of power. And all the men of Iran, when they learned thereof, were sore afraid, and they turned them once again unto the son of Saum. And they spake unto him hard words, and heaped reproaches upon him that he had not averted these dangers from their heads. And Zal in his heart smiled at their ingratitude and lipwisdom, but he also sorrowed with them and with his land. And he spake, saying-"I have ever done for you what was fitting and right, and all my life have I feared no enemy save only old age. But that enemy is now upon me, therefore I charge you that ye look unto Rustem to deliver you.
Howbeit he shall be backed by the counsels of his father."
Then he called before him his son, who was yet of tender age, and he said unto him-"O my son, thy lips still smell of milk, and thy heart should go out to pleasure. But the days are grave, and Iran looketh unto thee in its danger. I must send thee forth to cope with heroes."
And Rustem answered and said, "Thou knowest, O my father, that my desires are rather after war than pleasures. Give unto me, therefore, a steed of strength and the mace of Saum thy father, and suffer that I go out to meet the hosts of Ahriman."
Then Zal's heart laughed within him when he heard these words of manhood.
And he commanded that all the flocks of horses, both from Zaboulistan and Cabul, be brought before his son, that he might choose from their midst his steed of battle. And they were passed in order before Rustem, and he laid upon the backs of each his hand of might to test them if they could bear his weight of valour. And the horses shuddered as they bent beneath his grasp, and sank upon their haunches in weakness.
And thus did he do with them all in turn, until he came unto the flocks of Cabul. Then he perceived in their midst a mare mighty and strong, and there followed after her a colt like to its mother, with the chest and shoulders of a lion. And in strength it seemed like an elephant, and in colour it was as rose leaves that have been scattered upon a saffron ground. Now Rustem, when he had tested the colt with his eyes, made a running knot in his cord and threw it about the beast.
And he caught the colt in the snare, though the mare defended it mightily.
Then the keeper of the flock came before Rustem and said-"O youth puissant and tall, take not, I counsel thee, the horse of another."
And Rustem answered him and asked, "To whom then pertaineth this steed?
I see no mark upon its flanks."
And the keeper said, "We know not its master, but rumours are rife anent it throughout the land, and men name it the Rakush of Rustem.
And I warn thee, the mother will never permit thee to ride on it.
Three years has it been ready for the saddle, but none would she suffer to mount thereon."
Then Rustem, when he heard these words, swung himself upon the colt with a great bound. And the mare, when she saw it, ran at him and would have pulled him down, but when she had heard his voice she suffered it. And the rose-coloured steed bore Rustem along the plains like unto the wind. Then when he was returned, the son of Zal spake and said to the keeper-"I pray thee, tell unto me what is the price of this dragon?"
