Among the tribes of the Persians Herodotus mentions no tribe of Magi. It would be a mistake to conclude from this that there were originally no priests among the Persians, and to put faith in Xenophon's statement that Cyrus was the first to give the Magians the care of the sacred fire, "because he preferred to go on board with the pious rather than the impious."[320] No one will maintain that the Persians in ancient times were without worship and religious rites, or that when they accepted the doctrine of Zarathrustra, which did not permit sacrifice without Magians, they used the services of none but alien priests. Such a proceeding would be absurd. The proper conclusion from the fact that Herodotus does not mention a tribe of Magians among the Persians is that the priestly families there were less numerous; they had not broken away from the tribal connections to which they originally belonged, and formed themselves into a separate community. Further, from the fact that the priestly families of the Persians in old times had not formed themselves into a separate community, we may conclude--and indeed the conclusion follows from the position of Media and the notice in the Avesta about Ragha, and the observation about the ancient teachers of the Medes, who are said to have been followers of Zarathrustra--that the reform of the faith first came from Bactria to the Medes, that it was adopted and more strongly represented among them, and so passed on to the Persians. We cannot doubt that there were Persians belonging to the order of Magians. If Plato and his pupils call Zoroaster the "teacher of the Magians," and at the same time "a Persian," they must assume that there were Magians among the Persians; if, according to Plato's statement, the four teachers of the heirs to the Persian throne, of which one had to teach the Magism of Zoroaster, were selected out of "all the Persians;"--if at the time of Xerxes there were Persians who wrote on the doctrine of Zoroaster, they must have been initiated in the wisdom and knowledge of the Magians, and have known their invocations and customs; the contents of the holy scriptures and the scriptures themselves can hardly have been hidden from them. In order to prove that the Magians, _i.e._ the priests, belonged exclusively to the Medes, the fact has been brought forward that the Persians, after Darius had dethroned the Pseudo-Smerdis, celebrated each year the feast of the slaughter of the Magians, at which no Magian allowed himself to be seen, but all were obliged to remain at home.[321] The Magophonia was not the celebration of a victory over the Magi generally, but over the removal of a usurper, and the restoration of the dominion to the Achæmenids, which had been taken from them by one who happened to be a Magian. Herodotus at any rate calls this Magian a Mede.[322] Darius contents himself with calling him the "Magian." Hence there is no ground to doubt
