The modern worshippers of Alexander, however, have placed around his name all the possible glory of military achievement with a vast amount of rhetoric, concerning “the young hero” and “the thunder of his tread.” They claim, indeed, that he had very few faults, except cruelty, drunkenness, and some worse forms of dissipation. Their defense of this barbarous act is that “only the palace and its environs were burned” at this particular time, and that this was an act of requital for the pillage of Athens, and also to impress the Persians with a due sense of his own importance. Whatever may have been the motive, or physical condition, of the incendiary, it is highly probable that when the palace, and its environs were burned, the royal libraries went down in the flames, and certain it is, that from the time of the Macedonian conquest to the foundation of the Sassanian dynasty, the history of the Persian language and literature is almost a blank page. The legends of the Sassanian coins, the inscriptions of their emperors, and the translation of the Avesta, by Sassanian scholars, represent another phase of the language and literature of Īrān. The men who, at the rising of the new national dynasty, became the reformers, teachers, and prophets of Persia, formed their language and the whole train of their ideas upon a Semitic model. The grammar of the Sassanian dialect, however, was Persian, and “this was a period of religious and metaphysical delirium, when everything became everything, when Māyā and Sophia, Mitra and Christ, Virāf and Isaiah, Belus and Kronos were mixed up in one jumbled system of inane speculation, from which at last the East was delivered by the doctrines of Mohammed, and the West by the pure Christianity of the Teutonic nations.”[19] It was five hundred years after Alexander before Persian literature and religion were revived, and the books of the Zend-Avesta collected, either from scattered manuscripts or from oral tradition. The first collection of traditions, which finally resulted in the Shāh-Nāmah, was made also during the Sassanian dynasty. Firdusī tells us that there was a Pahlevan, of the family of the Dihkans,[20] who loved to study the traditions of antiquity. He therefore summoned from the provinces, all the old men who could remember portions of the ancient legends, and questioned them concerning the stories of the country. The Dihkan then wrote down the traditions of the kings and the changes in the empire as they had been recited to him. But this work, which was commenced under Nushirvan and finished under Yezdejird, the last of the Sassanians, was destroyed by the command of Omar, the Arabian chieftain.
