But, anciently, the word "Zend" implied something more than a simple interpretation of the "Avesta," or sacred texts. That interpretation was the source of certain new doctrines, the whole of which were considered orthodox, and designated _Zandi-agahi_, or Zend doctrines; doctrines which, it can hardly be doubted, supplied Plutarch and some other of the Greeks with ethical suggestions. The name _Pazend_, which frequently occurs in connection with _Avesta_ and _Zend_, denotes a further exposition of Zarathustrian teaching, as contained in the Vendidad, to which we shall shortly refer.
Thus far we have been indebted to Dr. Haug's account of the origin of the Zendavesta. His views are confirmed by Westergaard, who asserts that the sacred books belong to two epochs; that is, that they are written in one age, and collected and systematised in another, in much the same way as, according to Wolf, the Homeric poems were produced and assumed their present form. All the earlier traditions ascribe their origin to Zarathustra; but modern philologists affirm that they could not have sprung from any single mind, because they present no defined or self-consistent system of religious belief or moral economy. Like the hymns of the Vedas, and the strains of the Norse Edda, the several portions of the Zendavesta, so they say, must have been composed by different bards, each of whom coloured his particular theme according to the hues of his lively imagination. This theory, however, though it may have an element of truth in it, is hardly the whole truth. The Zendavesta is unquestionably wanting in unity and completeness. But it seems to us that traces of a dominant mind are everywhere visible; that the various parts are held together as on a thread by the teaching of Zarathustra himself; and that the additions made by later and inferior writers are not such as wholly to obscure the original work.
It is to the celebrated Frenchman, Anquetil Duperron, that the scholars of the West owe their knowledge of these remarkable books. Happening to see a facsimile of a few pages written in Zend characters, he resolved on setting out for India in order to purchase manuscripts of all the sacred books of the Zarathustrian religion, to acquire a thorough insight into their signification, and to obtain a knowledge of the rites and religious observances of the Parsees. His means being limited, he entered himself as a sailor on board a ship of the Dutch Indian Company, and worked his way out to Bombay in 1754. With money supplied by the French Government to assist him in his ingenious researches, he bribed one of the most learned _dustoors_ or priests, Dustoor Darat, or Surat, to procure the treasures he desired, and to instruct him in the Zend and Pehlvi languages. As soon as he had acquired the requisite proficiency, he addressed himself to the task of translating the whole of the Zendavesta into French. This was in 1759. Returning to Europe, he convinced himself of the genuineness of his purchases by comparing them with MSS. in the Bodleian Library; and, after several years of arduous labour, produced the first European version in 1771. At the outset, the authenticity of his work was challenged both in England and Germany; but all doubts have been set at rest by the inquiries of Rask and others; and thus, through the fanciful enterprise of a young Frenchman, the veil has been lifted which for so long a period shrouded the mysterious religion of the Magi.
