We must attempt to reach the goal by another path. I have already shown what was the condition of the sacred scriptures in Iran at the date of Alexander and the Seleucids (p. 55). Even before Hermippus of Smyrna, Aristotle had taught that the Magians considered that to be the best in the first instance which was first created, and maintained two principles, a good and evil deity, Oromazdes and Areimanius.155 Theopompus mentioned both these deities and the strife between them, and when he adds that there would one day be a time when the dead would rise again, and men would be immortal and able to withstand everything by their prayers – that after the victory of Oromazdes men would be happy and need no longer any sustenance, and would cast no shadow156– it will be seen below how definitely and exactly the doctrine of the Avesta is here reproduced. Hermodorus mentions a series of teachers, who succeeded the first teacher of the Magians, the "Persian Zoroaster," down to the campaign of Alexander of Macedon.157 With Eudoxus of Cnidus Zoroaster was the founder of the most beneficent wisdom; the pupils of Prodicus claimed to be acquainted with the writings of Zoroaster (p. 53). Plato calls him the son of Oromazdes, and adds that the heir to the throne was instructed in Magism as well as in the duty of being true during the whole of his life.158 The importance which the Avesta ascribes to truthfulness will become clear hereafter. If the Greeks of the fourth century could speak of Zoroaster as the teacher of the Persians, and put him in the closest relation with Auramazda, if they could reproduce correctly the names of the good and evil spirits and the main doctrines of the Avesta, it is an inevitable conclusion that the religion of Zarathrustra must have prevailed in the kingdom of the Achæmenids.
This result is confirmed by all the further information which we obtain from the Greeks. In Plutarch the last Darius calls on an eunuch, "to tell the truth in reverence for the great light of Mithra"; the eunuch replies that the king has no reason to accuse the evil spirit, and entreats "Lord Oromazdes," "that he may cause the light of the king to shine again."159 Artaxerxes II. was informed by his mother Parysatis that the Persians had received the law which distinguished good and evil from god. He swears "by Mithra," and Plutarch tells us how some related that when Darius, the eldest son of Artaxerxes, who sought his life, was slain, Artaxerxes went into the court of the palace and cried aloud to the Persians: "Rejoice, ye Persians, and tell it to others, that the great Oromazdes has executed judgment on those who imagined crime and wickedness."160 In Plutarch, Artaxerxes I. says to Themistocles: "May Areimanius ever implant such a disposition in my enemies that they may drive from themselves their best and bravest men."161 According to Deinon the Magians prophesied with branches in their hands, sacrificed under the open sky, and looked on fire and water as the only symbols of the divinity.162 Xenophon represents Cyrus as praising the gods and sacrificing to them every morning according to the instructions of the Magians.163 Though Herodotus does not mention either the name of Zarathrustra or of Auramazda, what he says of the rites of the Medes and Persians agrees exactly with the rules given in the Avesta. "Temples, images, and altars," he says, "are not erected by the Persians, because, as it seems to me, they do not believe like the Hellenes that the gods have the form and nature of men. They call the whole circle of heaven Zeus, and offer sacrifice to him after ascending the summits of mountains. Besides Zeus they have from ancient days sacrificed to the sun, the moon, the earth, water, winds, and fire, which among the Persians is a deity:164 the winds they also charm by songs. When offering sacrifice they build no altar and kindle no fire, nor pour libations, nor make any use of flutes, or cakes, or barley meal. If any one wishes to offer sacrifice he brings the victim to an open space, and calls on the god, after crowning his tiara with branches of myrtle. After cutting the animal in pieces, and cooking the flesh, he spreads out the most delicate grass, chiefly trefoil, and lays the flesh upon it. The Magian who stands by sings the theogony over it, for such, according to the Persians, is the nature of the prayer. After some time, the person who has made the sacrifice carries the flesh away and uses it for a feast. The Magians, in whose control is the worship by sacrifice, make it a great object to kill ants, serpents, and other creeping winged things: dogs and men only do they spare. No Persian may pollute a river, nor even wash in it, nor will they allow any one else to do so, for they have a great reverence for rivers. The bodies of the dead may not be burned; it is said indeed that the corpse of a Persian cannot be buried till it has been torn by a dog or a bird, and among the Magians this is an acknowledged practice. It is a meritorious act among the Persians to have many children, and he who can show the most receives gifts each year from the king. Each man celebrates the day on which he was born above all other days. What may not be done, may not be spoken of amongst the Persians: the most shameful action is lying, and the next to this is borrowing, for the reason that a man who has debts is generally compelled to lie. Any one afflicted by the itch or the leprosy may not come into the cities or mix with other Persians; and it is believed that such persons have sinned against the sun-god. Lepers from foreign lands are driven out of
