The result is this: Before the time of Alexander of Macedon, at the latest in the first half of the fourth century B.C., the Greeks were aware that Zoroaster had founded the doctrine of the Magians; in the last centuries B.C. and onwards it was known that he belonged to Bactria and Eastern Iran; but it was not till the fourth century A.D. that he was known to have lived under king Hystaspes; at any rate we have no older evidence on this point.
Much more recent in date, and of far less value, is the information derived from the East, with the exception of the Avesta, on Zarathrustra. It does not go back beyond the period of the Arabian empire over Iran. The Bundehesh, written in this period (p. 65, _n._ 3), contains a genealogy, which carries Zarathrustra's origin beyond Pourushaçpa and Haechataçpa, from whom, according to the Avesta, he was sprung (p. 38), through twelve generations to Manuschithra (Minocher). In the Avesta, the soul of the pure Manuschithra, the son of Airyu, is invoked;[137] it has been observed above that the national genealogy in Iran placed Thraetaona, and not Manu, at the head; Airyu, the son of Thraetaona, was the proper progenitor of the Airyas. With the name Manuschithra, _i.e._ scion of Manu, who is now the son of Airyu, this table passed back into the old Arian conception of the father Manu (p. 44). In the Avesta, Zarathrustra is connected by his father, the fourth sacrificer of the Haoma, with the old sacrificers; and by deriving his family from Manuschithra the Bundehesh places him in the closest relation to the progenitors of the Airyas. For the rest this book has little to say about the life of Zoroaster. It informs us that the house of Pourushaçpa lay on a hill on the river Daraja, a river which we cannot identify;[138] the Bundehesh places it in Airyana Vaeja (Airanvij), in a district which we must place in the high region of the Hindu Kush, on the sources of the Oxus (p. 31, _n_. 2), though the Bundehesh informs us that "it lay by the side of Atropatene." According to another passage in the book, Airyana Vaeja lay near the garden of Yima and Cashmere. In a third passage the garden of Yima, which we are compelled by unmistakable indications in the Avesta, to seek on the divine mountain, lies in the centre of Iran, under Mount Damkan.[139] Atropatene, as a name for the Alpine land in the north-west of Iran (now Aderbeijan), came into use in the time of the Greek empire; at any rate we cannot trace it earlier.[140] _Athrapaiti_ means "lord of fire"; _athrapata_, "one protected by fire"; in the remote mountains of this district the old fire-worship was preserved with peculiar zeal under the Seleucids; from the time of Ardeshir the Sassanids venerated the fire-temple Adar Guçasp (near Takht-i-Soliman), which lay in this region, above all others, and this was the reason why in the time of the Arabs it was thought that Airyana Vaeja must be sought there.[141] In any case it is impossible, out of regard to the Bundehesh and even later statements of the Moslem period, to place Zarathrustra in the north-west of Iran in order to represent him as a foreigner, reforming the religion of the north-east, when the Avesta, which distinctly places him in the east and puts him among the sacrificers and heroes of the east and rulers of Bactria, together with the older and more important evidence of the West, is on the opposite side.
