If the coincidence of the forms from Yima to Kava Huçrava with the Veda is a proof of the antiquity and genuineness of the tradition of the Avesta, the gain for history becomes less instead of greater. No one would take mythical persons for historical. Yet the style and form in which we find these traditional statements in the fragments of the Avesta supply certain guides for the lost history of Eastern Iran. The splendour of the royal majesty is so often and so distinctly brought into prominence, that the conclusion forces itself upon us, that the regions in which the Avesta arose, _i.e._ the north-east of Iran, must have been acquainted with a powerful and highly-respected monarchy. The ancient spirits of the sky are changed in the Avesta into mighty warriors and far-ruling kings, a circumstance in favour of the supposition that an empire once existed here, the image of which is reflected on prehistoric times. It is in Epic poems that the spirits of the first sky become heroes, and Epic poetry only arises in and follows on periods of war and conflict. The fact that the forms of the spirits thus changed into heroes by Epic song are turned into the forefathers of the kings and progenitors of the nation, further establishes the conclusion that a military monarchy must have been in existence here; only warlike princes could appear as the heirs of heroes. Moreover, the Avesta extols the high banner of Bakhdhi and speaks of the neighbouring regions as favoured; the later tradition of Iran marks out Bactria very clearly as the abode of Aurvataçpa and Vistaçpa; in the third century B.C. Bactria supplied its princes with means not merely to achieve their own independence, but to maintain it against the great kingdom of the Seleucids and to subjugate the land of the Indus (p. 25 ff.); and if, in addition to these facts, we bear in mind the conceptions found in the Median poems of the great power of the kings of the Bactrians, their treasures in gold and silver, their fortified city, the conquest of which was the greatest achievement of Ninus--we may venture to assume that before the days of the Medes, _i.e._ before the year 650 B.C., there must have existed an important monarchy in the north-east of Iran.
