We saw above that in the Avesta, Manuschithra and Airyu are connected with Thraetaona, and that the group of the Paradhatas comes to an end with these names. Hence Firdusi also represents the crown as being brought to the first ruler of the new group, Kai Kobad, _i.e._ the Kava Kavata of the Avesta, from the sky by two falcons; he also represents him as being fetched from Elburz, _i.e._ from the holy mountain of the old legend, in order to overcome Zohak, just as Thraetaona descended from the same mountain. Kai Kaus, the Kava Uça of the Avesta, who succeeded Kai Kobad, betrays his divine nature in Firdusi by his march against the demons, by the castles which these demons build for him on Elburz, and by his attempt to fly into heaven. In the Avesta Kava Uça offers sacrifice, in order to obtain the dominion over men and Daevas, and this favour is granted to him. That the march against the demons is made in the direction of Mazanderan is due no doubt to the frequent mention of the Mazanian Devs in the Avesta. Siavaksh, the son of Kai Kaus, who honourably gives himself up to the Turanians, is the Çyavarshana of the Avesta--from which we merely learn that he was spotless, and that after Kava Uça the royal majesty united with the beautiful body of Çyavarshana, and that he died by a violent death (p. 37). The destructive Turanian Franghraçyana, who is now called Afrasiab, is known to the Avesta. "Thrice," we are told, "he sought after the royal majesty which belongs to the Arian lands, but he found it not."[440] Kai Chosru, _i.e._ Kava Huçrava, is in the Avesta also the son of Çyavarshana; he offers sacrifice, in order that it may be granted to him "to put an end to the long period of dimness," "to bind the Franghraçyana filled with abundance;" he is said to be "without sickness and death." Firdusi's poem neglects none of these traits. After the triple war which, kindled by Afrasiab, has lasted for a long time, Firdusi represents Chosru as invoking the fire Guçasp, that Afrasiab may not escape him. In the Avesta the god Haoma is said himself to bind Franghraçyana, and to carry him away as a captive of king Huçrava, in order that the latter may slay him beyond the lake Chaechaçta (p. 37). In Firdusi the pious Hom discovers the hiding-place of Afrasiab; he binds him and carries him away a prisoner. Afrasiab escapes; but Hom captures him once more in lake Kanyesht. As Huçrava is "without sickness and death," Firdusi represents him as vanishing on a pilgrimage to heaven.
