This evidence from the West confirms the existence of sacred writings in Iran after the time of Alexander, and also indicates that they existed previously to that date; it contradicts the story of their destruction by the Macedonians. The books must have been in existence when Hermippus could speak of their extent, and quote rules from them; and writings of the kind must have been known when, in the days of Pausanias, the Magians could sing their invocations from a book. From other sources we are sufficiently informed that Alexander's efforts were not directed towards destroying the national character and traditional religion of the Persians. Arrian tells us that Magians no less than Greek soothsayers took part in their festivals.[90] Nor were the Seleucids more desirous than Alexander to effect the destruction of the Iranian nationality; just as the Ptolemies never attempted to set aside the Egyptian religion and life. Even if they had cherished such views, they were far from being strong enough to carry them out, for the Greek empire over Iran lasted in its integrity only eighty years. The Arsacids also, who recovered Iran from the Seleucids, were not averse to the Greek nation. They called themselves friends of the Hellenes, and not only was Greek spoken, but even the tragedies of Euripides were acted at their courts. The scanty remains of the monuments present us with echoes of Greek;[91] their coins, with few exceptions, bear Greek legends like those of the Bactrian princes whom they overcame. But though the influence of the Hellenic character continued under the Arsacids, and at the same time the Aramæan language and manners obtained even greater recognition than Hellenism during their dominion, the reign of the Arsacids was a restoration and revivification of the Iranian nationality. According to the evidence of western writers the Magians together with the members of the royal race formed the council of the Arsacids.[92] Pliny has already told us that these princes obeyed the rules of the Magians, and we also find that they invoked Mithra as the Achæmenids had done, and "saluted the sun."[93] Like the Achæmenids, too, they would not permit their armies to fight by night, and we are told that in their time the greatest weight was given to the love of truth and fidelity, _i.e._ to the virtues which, according to Herodotus, the Persians of his time considered the most important, and on which the Avesta insists above all others.[94] We also learn from western writers that the founder of the kingdom (Arsaces I.) was a descendant of Phriapites (Friyapaiti), and with his brother Tiridates and five others he slew the satrap of Antiochus Theos, and drove out the Macedonians;[95] just as Darius with the six Persian princes overthrew the dominion of Gaumata; and the Arabs relate that the Arsacids trace back their stock to Çyavarshana, the son of Kava Uça, a story which cannot have been invented in Arabia.[96] In the list of the Arsacids we also find the name Chosru (108-130 A.D.), the Kava Huçrava of the old legend (p. 37); on the coins we find a Vologeses and a Phraates before the fire-altar, the characteristic symbol of the ancient worship of Iran. Just as the old Arian character appears beside the Greek on the coins of the Greek princes of Bactria, the Greek character on the coins of the Arsacids gradually degenerates until at length it gives way to a new Iranian character and language. The tradition sketched in the Dinkart, as we have seen, represents the Arsacid Vologeses (which of the four princes of the name is meant is not clear)[97] as collecting what fragments remained of the holy scriptures in the memory of the priests. The burning of the scriptures by Alexander, as related in the books of the Parsees on their exodus and the Arda Viraf, is merely a transference to him of the conduct of the Moslems on their conquest of Iran. Of the continuance of the ancient religion of Iran under the Arsacids there can be no doubt, though it is true that along with it, in the Greek cities which Alexander and the Seleucids founded, and which were independent within their walls even under the Parthians, Hellenic rites were practised. In these cities Syrian modes of worship were also permitted, and the Aramaic language and culture found entrance into Iran.[98]
