king, and over-against the king the imperial banner. In keeping with this, the ascendency of the nobility in the Parthian empire goes hand in hand with the privileged position of the clergy. The priests of this religion, the Magians, appear already in the documents of the Achaemenids and in the narratives of Herodotus, and have, probably with right, always been regarded by the Occidentals as a national Persian institution. The priesthood was hereditary, and at least in Media, presumably also in other provinces, the collective body of the priests was accounted, somewhat like the Levites in the later Israel, as a separate portion of the people. Even under the rule of the Greeks the old religion of the state and the national priesthood maintained their place. When the first Seleucus wished to found the new capital of his empire, the already mentioned Seleucia, he caused the Magians to fix day and hour for it, and it was only after those Persians, not very willingly, had cast the desired horoscope, that the king and his army, in accordance with their indication, accomplished the solemn laying of the foundation-stone of the new Greek city. Thus by his side stood the priests of Ahura Mazda as counsellors, and they, not those of the Hellenic Olympus, were interrogated in public affairs, so far as these concerned divine things. As a matter of course this was all the more the case with the Arsacids. We have already observed that in the election of king, along with the council of the nobility, that of the priests took part. King Tiridates of Armenia, of the house of the Arsacids, came to Rome attended by a train of Magians, and travelled and took food according to their directions, even in company with the emperor Nero, who gladly allowed the foreign wise men to preach their doctrine and to conjure spirits for him. From this certainly it does not follow that the priestly order as such exercised an essentially determining influence on the management of the state; but the Mazda-faith was by no means re-established only by the Sassanids; on the contrary, amidst all change of dynasties, and amidst all its own development, the religion of the land of Iran remained in its outline the same.
