A book of the Parsees of India, which tells the story of their flight from their ancient home, relates that Iskander (Alexander of Macedon) burned the revealed scriptures, and the faithful were persecuted for 300 years. When Ardeshir (the first Sassanid) ascended the throne, the true faith was restored, under the superintendence of Arda Viraf. After this the true religion was again suspended till king Shapur (Shapur II.) rose and once more made the faith famous, and Aderbat Mahresfant girded his loins in the good cause. The same account is given in the Book of Arda Viraf, also a book of the Parsees of India. From this we learn that the religion received by the pious Zarathrustra lasted for 300 years in purity. Then the evil one stirred up Iskander Rumi, so that he spread war and devastation over Iran, and slew the rulers of the land. The Avesta which was preserved at Stakhar Papakan (Persepolis), written on cow-skins with golden ink, he burned, and put to death many priests and judges, pillars of the faith, and spread hatred, strife, and confusion among the people of Iran. They had now no lord, guide, and high priest, who knew their religion; they were full of doubts and had different modes of belief and worship of various kinds, and different laws prevailed in the world till the time when Ardeshir came to the throne and listened to the words of the holy Arda Viraf and believed him. But after Ardeshir's death a schism broke out, and more than 40,000 souls fell away from the true faith, till the day when the holy Aderbat Mahresfant arose.[77] An older writing of the Parsees, the Dinkart (composed under the Sassanids), tells us, apparently on the ground of a proclamation of the Sassanid Chosru Parvez (590-627 A.D.) that king Vistaçpa of Bactria had commanded that all books which were written in the language of the Magians should be collected, in order that the faith of the worshippers of Auramazda might have some support, and all men were to go to Frashaostra (whom the Avesta mentions as a companion of Zarathrustra) to be instructed in the faith. And Darai, the son of Darai (Darius Hystaspis is meant), commanded that two copies of the entire Avesta, precisely as Zarathrustra had received it from Auramazda, should be preserved, the one in the treasury at Shapikan, and the other in the city of scriptures. Then Valkosh (Vologeses), the descendant of Ashkan (Arsaces), gave orders that so much of the Avesta as had escaped destruction and the ravages of Iskander and the warriors of Rum, and existed in fragments or in oral tradition, should be sought out and brought from every city. And king Artakshatr (Ardeshir) summoned the Herbedh (_i.e._ the priest)[78] Tosar with the holy scriptures, which were scattered, to his residence, and when Tosar came he gave command to the other priests that everything, which differed from that which was now considered to be knowledge and wisdom, should be suppressed.
