A great similarity to Herodotus’ version of the Kyros myth is found in the early history of the Iranese royal hero, Kaikhosrav, as related by _Firdusi_, in the Sâh-nâme. This myth is most extensively rendered by Spiegel (Eranische Altertumskunde, I, 581 et seq.). During the warfare of King Kaikaus of Baktria and Iran, against King Afrâsiâb of Turan, _Kaikaus fell out with his son, Siâvaksh_, who applied to Afrâsiâb for protection and assistance. He was kindly received by Afrâsiâb, who gave him his daughter Feringis to wife, on the persuasion of his Wesir, Pirân, _although he had received the prophecy that the son to be born of this union would bring great misfortune upon him_. Garsevaz, the king’s brother, and a near relative of Siâvaksh, calumniates the son-in-law, and Afrâsiâb leads an army against him. _Before the birth of his son, Siâvaksh is warned by a dream, which foretold destruction and death to himself, but royalty to his offspring._ He therefore flies from Afrâsiâb, but is taken prisoner and killed, on the command of the Sâh. His wife, who is pregnant, is saved by Pirân from the hands of the murderers. On condition of announcing at once the delivery of Feringis to the king, Pirân is granted permission to keep her in his house. The shade of the murdered Siâvaksh once comes to him in a dream, and tells him that an avenger has been born, and Pirân actually finds in the room of Feringis a newborn boy, whom he names Kaikhosrav. Afrâsiâb no longer insisted upon the killing of the boy, but he ordered Pirân _to surrender the child with a nurse to the herders, who were to raise him in ignorance of his origin_. But his royal descent is promptly revealed in his courage and his demeanor; and as Pirân takes the boy back into his home, Afrâsiâb becomes distrustful, and orders the boy to be led before him. Instructed by Pirân, Kaikhosvrav plays the fool,[50] and reassured as to his harmlessness, the Sâh dismisses him to his mother, Feringis. Finally, Kaikhosvrav is crowned as king by his grandfather, Kaikaus. After prolonged, complicated, and tedious combats, Afrâsiâb is at last taken prisoner, with divine assistance. Kaikhosvrav strikes his head off, and also causes Garsivaz to be decapitated.
