So he caused dromedaries to be sent forth...
So he caused dromedaries to be sent forth, even unto the borders of the land, and bring forth wood from the forests. And they did so, and there was reared a mighty heap of logs, so that the eye could behold it at a distance of two farsangs. And it was piled so that a path ran through its midst such as a mounted knight could traverse.
And the Shah commanded that naphtha be poured upon the wood; and when it was done he bade that it be lighted, and there were needed two hundred men to light the pyre, so great was its width and height. And the flames and smoke overspread the heavens, and men shouted for fear when they beheld the tongues of fire, and the heat thereof was felt in the far corners of the land.
Now when all was ready, Kai Kaous bade Saiawush his son ride into the midst of the burning mount, that he might prove his innocence. And Saiawush did as the King commanded, and he came before Kai Kaous, and saluted him, and made him ready for the ordeal. And when he came nigh unto the burning wood, he commended his soul unto God, and prayed that He would make him pure before his father. And when he had done so, he gave rein unto his horse, and entered into the flame.
And a great cry of sorrow arose from all men in the plains and in the city, for they held that no man could come forth alive from this furnace. And Sudaveh heard the cry, and came forth upon the roof of her house that she might behold the sight, and she prayed that ill might befall unto Saiawush, and she held her eyes fastened upon the pyre. But the nobles gazed on the face of Kai Kaous, and their mouths were filled with execrations, and their lips trembled with wrath at this deed.
And Saiawush rode on undaunted, and his white robes and ebon steed shone forth between the flames, and their anger was reflected upon his helmet of gold. And he rode until he was come unto the end of the pathway, and when he came forth there was not singed a hair of his head, neither had the smoke blackened his garments. Now when the people beheld that he was come forth alive, they rent the welkin with their shouting.
And the nobles came forth to greet him, and, save only Sudaveh, there was joy in all hearts. Now Saiawush rode till he came before the Shah, and then he got him off his horse, and did homage before his father. And when Kai Kaous beheld him, and saw that there were no signs of fire about him, he knew that he was innocent.
