Lohurasp reigned in wisdom upon the crystal throne, and Iran was as wax under his hands. And men were content under his sway, save only Gushtasp, his son, who was rebellious of spirit. And Gushtasp was angered because his father would not abandon unto him the sovereignty. Wherefore, when he beheld that his pleading was vain, he stole away from Iran and sought out the land of Roum, and the city that Silim his forefather had builded. And he did great deeds of prowess in the land, so that the King gave unto him his daughter to wife.

Now Lohurasp, when he learned of the mighty deeds done of his son, strove to win him back unto himself. So he sent forth messengers bearing words of greeting and entreated of Gushtasp that he would return unto the courts of his father. And he sware unto him that if he would listen unto his voice, he would abandon unto him the throne. So Gushtasp listened to the voice of his father, and he returned him unto Iran. And Lohurasp stepped down from off the throne of the Kaianides and gave place unto Gushtasp, his son. And one hundred and twenty years had he reigned in equity, and now that it was done he hid himself within the temples of Balkh, that he might live in the sight of God, and make him ready to meet his end. And Gushtasp, his son, ruled the land worthily, and he administered justice in such wise that sheep could drink at the same brook as the wolves.

Now when he had sat some while upon the throne, there appeared in the land Zerdusht, the prophet of the Most High. And he came before the Shah and taught him, and he went out in all the land and gave unto the people a new faith. And he purged Iran of the might of Ahriman. He reared throughout the realm a tree of goodly foliage, and men rested beneath its branches. And whosoever ate of the leaves thereof was learned in all that regardeth the life to come, but whosoever ate of the branches was perfect in wisdom and faith. And Zerdusht gave unto men the Zendavesta, and he bade them obey its precepts if they would attain everlasting life.

But tidings concerning Zerdusht were come even unto Arjasp, who sat upon the throne of Afrasiyab, and he said within himself, "This thing is vile." So he refused ear unto the faith, and he sent a writing unto Gushtasp, wherein he bade him return unto the creed of his fathers. And he said-

"If thou turn thee not, make thee ready for combat; for verily I say unto thee, that unless thou cast out Zerdusht, this man of guile, I will overthrow thy kingdom and seat me upon thy throne."

When Gushtasp heard the haughty words that Arjasp had spoken, he marvelled within himself. Then he called before him a scribe, and sent back answer unto Arjasp. And he said that he would deliver up unto the sword whosoever swerved from the paths of Zerdusht, and whosoever would not choose them, him also would he destroy. And he bade him, therefore, get ready to meet Iran in battle. Then when he had sent this writing, Gushtasp got together his hosts and mustered them, and he beheld that they outnumbered the grass upon the fields. And the dust that uprose from their feet darkened the sky, and the neighing of their horses and the clashing of their armour were heard above the music of the cymbals. And the banners pierced the clouds like to trees that grow upon a mountain. And Gushtasp gave the command of this host unto Isfendiyar, his son. And Isfendiyar was a hero of renown, and his tongue was a bright sword, and his heart was bounteous as the ocean, and his hands were like the clouds when rain falls to gladden the earth. And he took the lead of the army, and he led it forth into Turan.

Now when the men of Turan and of Iran met in conflict, a great battle was waged between them, and for the space of twice seven days they did not cease from combat, neither did any of the heroes close their eyes in slumber. And their rage was hot one against another, but in the end the might of Iran overcame, and Arjasp fled before the face of Isfendiyar.

Then Isfendiyar returned him unto Iran, and presented himself before his father, and demanded a blessing at his hands. But Gushtasp said-

"The time is not yet come when thou shouldest mount the throne."
So he sent him forth yet again that he might turn all the lands unto the faith of Zerdusht. And Isfendiyar did as Gushtasp commanded.

Now while he was gone forth there came before the Shah one Gurjam, who was of evil mind and foe unto Isfendiyar. And he spake ill of Isfendiyar unto his father, and he said unto Gushtasp that his son strove to wrest from him the sovereignty. And Gushtasp, when he learned it, was wroth, and he sent forth messengers that they should search out Isfendiyar, and bring him before the Shah in the assembly of the nobles. And when Isfendiyar was come, Gushtasp spake not unto him in greeting, but he turned him to his nobles, and he recounted unto them a parable. Then he told unto them of a son who sought to put to death his father, and he asked of them what punishment this father should mete out unto his child. And the nobles cried with one accord-

"This thing which thou relatest unto us, it is not right, and if there be a son so evil, let him be put into chains and cast in bondage."

Then Gushtasp said, "Let Isfendiyar be put into chains."
And Isfendiyar opened his mouth in vain before his father, for Gushtasp would not listen unto his voice. So they cast him out into a dungeon, and chains of weight were hung upon him, and the daylight came not nigh unto him, neither did joy enter into his heart. And he languished many years, and the heart of the Shah was not softened towards him.

Now when Arjasp learned that the might of Isfendiyar was fettered, and that Gushtasp was given over to pleasures, he gathered together an army to fall into Iran and avenge the defeat that was come upon his hosts. So he fell upon Balkh before any were aware of it and he put to death Lohurasp the Shah and he made captive the daughters of Gushtasp. And Arjasp threw fire into the temples of Zerdusht and did much destruction unto the city and it was some while ere Gushtasp learned that which he had done. But when he had news thereof he was dismayed, and he called together his army and put himself at their head. But the Turanians were mightier than he, and they routed him utterly, and Gushtasp fled before their face. Then the Shah called together his nobles, and consulted with them how he should act in these sore straits. And one among them who was wise above the rest said-

"I counsel thee that thou release Isfendiyar, thy son, and that thou give to him the command, for he alone can deliver the land."

And Gushtasp said, "I will do as thou sayest, and if Isfendiyar shall deliver us from this foe, I will abandon unto him the throne and the crown."

Then he sent messengers unto Isfendiyar that they should unbind his chains. But Isfendiyar, when they came before him, closed ear unto their voice. And he said-

"My father hath kept me in bondage until he hath need of me. Why therefore should I weary me in his cause? I will not go unto his aid."
