Jamásp appointed officers to ascertain the number of killed in the battle. Of Iránians there were thirty thousand, among whom were eight hundred chiefs; and the enemy's loss amounted to nine hundred thousand, and also eleven hundred and sixty-three chiefs. Gushtásp rejoiced at the glorious result, and ordered the drums to be sounded to celebrate the victory, and he increased his favor upon Zerdusht, who originated the war, and told him to call his triumphant son, Isfendiyár, near him.
The gallant youth the summons hears,
And midst the royal court appears,
Close by his father's side,
The mace, cow-headed, in his hand;
His air and glance express command,
And military pride.
Gushtásp beholds with heart elate.
The conqueror so young, so great,
And places round his brows the crown,
The promised crown, the high reward,
Proud token of a mighty king's regard,
Conferred upon his own.
After Gushtásp had crowned his son as his successor, he told him that he must not now waste his time in peace and private gratification, but proceed to the conquest of other countries. Zerdusht was also deeply interested in his further operations, and recommended him to subdue kingdoms for the purpose of diffusing everywhere the new religion, that the whole world might be enlightened and edified. Isfendiyár instantly complied, and the first kingdom he invaded was Rúm. The sovereign of that country having no power nor means to resist the incursions of the enemy, readily adopted the faith of Zerdusht, and accepted the sacred book named Zendavesta, as his spiritual instructor. Isfendiyár afterwards invaded Hindústán and Arabia, and several other countries, and successfully established the religion of the fire-worshippers in them all.
Where'er he went he was received
With welcome, all the world believed,
And all with grateful feelings took
The Holy Zendavesta-book,
Proud their new worship to declare,
The worship of Isfendiyár.
The young conqueror communicated by letters to his father the success with which he had disseminated the religion of Zerdusht, and requested to know what other enterprises required his aid. Gushtásp rejoiced exceedingly, and commanded a grand banquet to be prepared. It happened that Gurzam a warrior, was particularly befriended by the king, but retaining secretly in his heart a bitter enmity to Isfendiyár, now took an opportunity to gratify his malice, and privately told Gushtásp that he had heard something highly atrocious in the disposition of the prince. Gushtásp was anxious to know what it was; and he said, "Isfendiyár has subdued almost every country in the world: he is a dangerous person at the head of an immense army, and at this very moment meditates taking Balkh, and making even thee his prisoner!
"Thou know'st not that thy son Isfendiyár
Is hated by the army. It is said
Ambition fires his brain, and to secure
The empire to himself, his wicked aim
Is to rebel against his generous father.
This is the sum of my intelligence;
But thou'rt the king, I speak but what I hear."
These malicious accusations by Gurzam insidiously made, produced great vexation in the mind of Gushtásp. The banquet went on, and for three days he drank wine incessantly, without sleep or rest because his sorrow was extreme. On the fourth day he said to his minister: "Go with this letter to Isfendiyár, and accompany him hither to me." Jamásp, the minister, went accordingly on the mission, and when he arrived, the prince said to him, "I have dreamt that my father is angry with me."—"Then thy dream is true," replied Jamásp, "thy father is indeed angry with thee."—"What crime, what fault have I committed?
"Is it because I have with ceaseless toil
Spread wide the Zendavesta, and converted
Whole kingdoms to that faith? Is it because
For him I conquered those far-distant kingdoms,
With this good sword of mine? Why clouds his brow
Upon his son—some demon must have changed
His temper, once affectionate and kind,
Calling me to him thus in anger! Thou
Hast ever been my friend, my valued friend
Say, must I go? Thy counsel I require."
"The son does wrong who disobeys his father,
Despising his command," Jamásp replied.
