Persia was more studied and less understood than it had ever been before. The real object aimed at, in studying the old religion, was to form a new one. Throughout the Middle Ages nothing was known of Mazdeism but the name of its founder, who from a Magus was converted into a magician and master of the hidden sciences. It was not until the Renaissance that real inquiry was resumed. The first step was to collect all the information that could be gathered from Greek and Roman writers. That task was undertaken and successfully completed by Barnabé Brisson. A nearer approach to the original source was made in the following century by Italian, English, and French travellers in Asia. Pietro della Valle, Henry Lord, Mandelslo, Ovington, Chardin, Gabriel du Chinon, and Tavernier, found Zoroaster's last followers in Persia and India, and made known their existence, their manners, and the main features of their belief to Europe. Gabriel du Chinon saw their books and recognized that they were not all written in the same language, their original holy writ being no longer understood except by means of translations and commentaries in another tongue. In the year 1700, a professor at Oxford, Thomas Hyde, the greatest Orientalist of his time in Europe, made the first systematic attempt to restore the history of the old Persian religion by combining the accounts of the Mohammedan writers with "the true and genuine monuments of ancient Persia." Unfortunately the so-called genuine monuments of ancient Persia were nothing more than recent Persian compilations or refacimenti. But notwithstanding this defect, which could hardly be avoided then, and a distortion of critical acumen, the book of Thomas Hyde was the first complete and true picture of modern Parsîism, and it made inquiry into its history the order of the day. A warm appeal made by him to the zeal of travellers, to seek for and procure at any price the sacred books of the Parsis, did not remain ineffectual, and from that time scholars bethought themselves of studying Parsîism in its own home. Eighteen years later, a countryman of Hyde, George Boucher, received from the Parsis in Surat a copy of the Vendîdâd Sâda, which was brought to England in 1723 by Richard Cobbe. But the old manuscript was a sealed book, and the most that could then be made of it was to hang it by an iron chain to the wall of the Bodleian Library, as a curiosity to be shown to foreigners. A few years later, a Scotchman, named Fraser, went to Surat, with the view of obtaining from the Parsis, not only their books, but also a knowledge of their contents. He was not very successful in the first undertaking, and utterly failed in the second.
