If the Paradhatas, Yima, Athwya, Thraetaona, Thrita, and Kereçaçpa in the original conception are spirits of the sky, if the monsters with which Thraetaona and Kereçaçpa struggle are not to be sought on earth but in the heavens, if in these dragons we find once more the cloud-serpents, against which Indra and his company have to contend--we do not at once set foot upon earth, when we come to the Kavanians. According to the later tradition of Iran, Kava Kavata was fetched from the divine mountain in order to reign over the country; two white falcons bring him a golden crown. The Rigveda mentions Kavya Uçanas, _i.e._ Uçanas, the son of Kavi, who brings the cows of the sky, _i.e._ the clouds, to the pasture.[74] In the Avesta, Kava Uça sacrifices not only to rule over the whole earth but also over the spirits. According to a later tradition this sovereign--now called Kai Kaus--causes beautiful castles to be built on the divine mountain by the demons, and is then carried by four eagles into heaven. Kava Huçrava, for whom in the Avesta the god Haoma contends, is without sickness and death (p. 37). In the later tradition, in which he is known as Kai Chosru, he begins a pilgrimage to heaven after conquering and slaying his opponent the Turanian Franghaçiana, like the sons of Pandu in the Mahabharata after their victory over the Kurus and their happy reign. Like them also, Kai Chosru climbs the mountains and disappears from his companions at a well. Against his command they seek him in the mountains, and are all buried in a great snow-storm. From the name Manuschithra (p. 37), _i.e._ scion of Manu, we may conclude that the twin brother of Yama, "father Manu," was not unknown to the Arians of Iran. But the genealogy in which the Avesta has preserved these names has no greater claims to historical value than the figures which have passed in review before us. Airyu is the son of Thraetaona; _i.e._ from the mightiest hero, the slayer of the great dragon, are sprung the sovereigns and the nation of the Airyas; the son of Airyu is Manuschithra; from whose son, Naotara, are derived the two last Kavas, Aurvataçpa and Vistaçpa.
