But Soudabeh, when she had so far accomplished her longing that she had gotten him within the house, desired that he should speak with her alone. But Siawosh resisted her wish. And three times did Soudabeh entice him behind the curtains of the house, and three times was Siawosh cold unto her yearning. Then Soudabeh was wroth, and she made complaint unto the King, and she slandered the fair fame of Siawosh, and she spread evil reports of him throughout the land, and she inflamed the heart of Kay-Kavous against his son. Now the King was angered beyond measure, and it availed nought unto Siawosh to defend himself, for Kay-Kavous was filled with the love of Soudabeh, and he listened only unto her voice. And he remembered how she had borne his captivity in Hamavaran, and he knew not of her evil deceits. And when she said that Siawosh had done her great wrong, Kay-Kavous was troubled in his spirit, and he resolved how he should act, for his heart went out also unto his son, and he feared that guile lurked in these things. And he could not decide between them. 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 King 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.
If Siawosh is the hero then Soudabeh can be considered the villain since her lies led him to go through a lot of pain. She is illustrated as a woman who harbors intimate feeling for her step son and spreads ill things about him when he did not comply with her feelings. Since Kay-Kavous liked her dearly, he could not go against her. However, he never made an effort to ask his son and clear all the misunderstandings there and then. Or it could be that men were supposed to prove their innocence through illogical tests and strengths rather than simply answering the questions honestly. Likewise, had he failed and died during the process, would an innocent person be branded as a criminal? And why was Soudabeh not questioned? How can words enough to prove that she was innocent yet his son was not?
