Mr. Maurice’s _Boyle Lectures on the Religions of the World_ refer to this subject; and some useful remarks exist in Morell’s _Philosophy of Religion_,(c. iii. and iv.) But the book most full of information is the interesting _Christian Advocate’s Publication_, of the late archdeacon Hardwick, _Christ and other Masters_; a work full of learning and piety, unfortunately left unfinished by the tragedy of his premature death in August 1859. In the parts published he has compared Christianity with the Egyptian and Persian religions (part iv.), with the Hindoo (part ii.), and the Chinese (part iii.); and he was preparing materials for its comparison with the Teutonic, and with those of the classic nations. Note 3. p. 4. Zend And Sanskrit Literature. The purpose of this note is to indicate the sources of information in reference to (1) the Zend and (2) the Sanskrit literature, for illustrating the comparative history of religion. 1. It was about the middle of the last century (1762) that Anquetil du Perron brought manuscripts to Europe from Guzerat, written in the Zend or ancient Persian tongue. For some time the relation of the language to the Sanskrit was not understood. The great scholar to whom are due both the study of the tongue and the editing of the _Yaçna_, was Eugene Burnouf. The work just named is the first of the three works which make up the _Vendidad Sadé_; parts of which possibly go back to a period almost coeval with Zoroaster, i.e. perhaps the sixth century B.C. Two other works exist for the study of the Persian theology, though much more modern in date,—the _Desatir_ of the ninth century A.D., and the _Dabistan_ of the seventeenth,—which both contain fragments of ancient traditions embedded in their texts. The _Avesta_, of which the _Vendidad_ is one of the oldest parts, has been edited by Spiegel. References to the older literature concerning it may be found in Heeren’s _History of the Asiatic Nations_, vol. i. ch. ii. An account of the present results of comparative philology in reference to Persian is given by professor Max Müller in Bunsen’s _Philosophy of History_, vol. i. p. 110. E. T. The Persian theology brought to light by these investigations is discussed by A. Franck, in a paper, _Les Doctrines Religieuses et Philosophiques de la Perse_, in his _Etudes Orientales_, 1861; also in Dr. John Wilson’s _Parsi Religion_, 1843; Martin Haug’s _Essays on the Parsis_, 1861, founded on Burnouf’s researches; and in archdeacon Hardwick’s _Christ and other Masters_, part iv. ch. iii. (Hyde’s _Hist. Relig. Vet. Pers._ 1700, is obsolete.)
