The trustees of the British Museum recognised that the problem of the Rosetta Stone was one on which the scientists of the world might well exhaust their ingenuity, and they promptly published a carefully lithographed copy of the entire inscription, so that foreign scholarship had equal opportunity with British to try to solve the riddle. How difficult a riddle it was, even with this key in hand, is illustrated by the fact that, though scholars of all nations brought their ingenuity to bear upon it, nothing more was accomplished for a dozen years than to give authority to three or four guesses regarding the nature of the upper inscriptions, which, as it afterwards proved, were quite incorrect and altogether misleading. This in itself is sufficient to show that ordinary scholarship might have studied the Rosetta Stone till the end of time without getting far on the track of its secrets. The key was there, but to apply it required the inspired insight--that is to say, the shrewd guessing power--of genius. The man who undertook the task had perhaps the keenest scientific imagination and the most versatile profundity of knowledge of his generation--one is tempted to say, of any generation. For he was none other than the extraordinary Dr. Thomas Young, the demonstrator of the vibratory nature of light. Young had his attention called to the Rosetta Stone by accident, and his usual rapacity for knowledge at once led him to speculate as to the possible aid this tri-lingual inscription might give in the solution of Egyptian problems. Resolving at once to attempt the solution himself, he set to work to learn Koptic, which was rightly believed to represent the nearest existing approach to the ancient Egyptian language. His amazing facility in the acquisition of languages stood him in such good stead that within a year of his first efforts he had mastered Koptic and assured himself that the ancient Egyptian language was really similar to it, and had even made a tentative attempt at the translation of the Egyptian scroll. His results were only tentative, to be sure, yet they constituted the very beginnings of our knowledge regarding the meaning of hieroglyphics. Just how far they carried has been a subject of ardent controversy ever since. Not that there is any doubt about the specific facts; what is questioned is the exact importance of these facts. For it is undeniable that Young did not complete and perfect the discovery, and, as always in such matters, there is opportunity for difference of opinion as to the share of credit due to each of the workers who entered into the discovery.
