Kai-káús and his warriors to sight. Rustem was not long in applying the
miraculous remedy, and the moment the blood touched their eyes, the
fearful blindness was perfectly cured.

The champion brought the Demon's heart,
And squeezed the blood from every part,
Which, dropped upon the injured sight,
Made all things visible and bright;
One moment broke that magic gloom,
Which seemed more dreadful than the tomb.

The monarch immediately ascended his throne surrounded by all his
warriors, and seven days were spent in mutual congratulations and
rejoicing. On the eighth day they all resumed the saddle, and proceeded
to complete the destruction of the enemy. They set fire to the city, and
burnt it to the ground, and committed such horrid carnage among the
remaining magicians that streams of loathsome blood crimsoned all the
place.

Káús afterwards sent Ferhád as an ambassador to the king of Mázinderán,
suggesting to him the expediency of submission, and representing to him
the terrible fall of Arzang, and of the White Demon with all his host,
as a warning against resistance to the valor of Rustem. But when the
king of Mázinderán heard from Ferhád the purpose of his embassy, he
expressed great astonishment, and replied that he himself was superior
in all respects to Káús; that his empire was more extensive, and his
warriors more numerous and brave. "Have I not," said he, "a hundred
war-elephants, and Káús not one? Wherever I move, conquest marks my way;
why then should I fear the sovereign of Persia? Why should I submit to
him?"
