The priests of the Zoroastrians, from a time not long subsequent to Darius Hystaspis, were the Magi. This tribe, or caste, originally perhaps external to Zoroastrianism, had come to be recognized as a true priestly order; and was intrusted by the Sassanian princes with the whole control and direction of the religion of the state. Its chief was a personage holding a rank but very little inferior to the king. He bore the title of Tenpet, “Head of the Religion,” or Movpetan Movpet, “Head of the Chief Magi.” In times of difficulty and danger he was sometimes called upon to conduct a revolution; and in the ordinary course of things he was always reckoned among the monarch’s chief counsellors. Next in rank to him were a number of Movpets, or “Chief Magi,” called also destoors or “rulers,” who scarcely perhaps constituted an order, but still held an exalted position. Under these were, finally, a large body of ordinary Magi, dispersed throughout the empire, but especially congregated in the chief towns.

This consisted of a tall peaked cap of felt or some similar material, having deep lappets at the side, which concealed the jaw and even the lips, and a long white robe, or cloak, descending to the ankles. They assembled often in large numbers, and marched in stately processions, impressing the multitude by a grand and striking ceremonial. Besides the offerings which were lavished upon them by the faithful, they possessed considerable endowments in land, which furnished them with an assured subsistence. They were allowed by Chosroes the First a certain administrative power in civil matters; the collection of the revenue was to take place under their supervision; they were empowered to interfere in cases of oppression, and protect the subject against the tax-gatherer.

A fire-temple was maintained in every important city throughout the empire; and in these a sacred flame, believed to have been lighted from heaven, was kept up perpetually, by the care of the priests, and was spoken of as “unextinguishable.” Fire-altars probably also existed, independently of temples; and an erection of this kind maintained from
