Here, then, in an essay written nearly a hundred years ago by Sir W. Jones, one of the most celebrated Oriental scholars in England, it might seem as if we should find the first outlines of that science which is looked upon as but of to-day or yesterday—the outlines of Comparative Mythology. But in such an expectation we are disappointed. What we find is merely a superficial comparison of the mythology of India and that of other nations, both Aryan and Semitic, without any scientific value, because carried out without any of those critical tests which alone keep Comparative Mythology from running riot. This is not intended as casting a slur on Sir W. Jones. At his time the principles which have now been established by the students of the science of language were not yet known, and as with words, so with the names of deities, similarity of sound, the most treacherous of all sirens, was the only guide in such researches. It is not pleasant to have to find fault with a man possessed of such genius, taste, and learning as Sir W. Jones, but no one who is acquainted with the history of these researches will be surprised at my words. It is the fate of all pioneers, not only to be left behind in the assault which they had planned, but to find that many of their approaches were made in a false direction, and had to be abandoned. But as the authority of their names continues to sway the public at large, and is apt to mislead even painstaking students and to entail upon them repeated disappointments, it is necessary that those who know should speak out, even at the risk of being considered harsh or presumptuous. A few instances will suffice to show how utterly baseless the comparisons are which Sir W. Jones instituted between the gods of India, Greece, and Italy. He compares the Latin Janus with the Sanskrit deity Ganesa. It is well known that Janus is connected with the same root that has yielded the names of Jupiter, Zeus, and Dyaus, while Ganesa is a compound, meaning lord of hosts, lord of the companies of gods. Saturnus is supposed to have been the same as Noah, and is then identified by Sir W. Jones with the Indian Manu Satyavrata, who escaped from the flood. Ceres is compared with the goddess Sri, Jupiter or Diespiter with Indra or Divaspati; and though etymology is called a weak basis for historical inquiries, the three syllables Jov in Jovis, Zeu in Zeus, and Siv in Siva are placed side by side, as possibly containing the same root, only differently pronounced. Now the s of Siva is a palatal s, and no scholar who has once looked into a book on Comparative Philology need be told that such an s could never correspond to a Greek Zeta or a Latin J.
