Curiously enough, it was a trilingual inscription that gave the clew, as in the case of the Rosetta Stone, though with very striking difference withal. The trilingual inscription now in question, instead of being a small, portable monument, covers the surface of a massive bluff at Behistun in western Persia. Moreover, all three of its inscriptions are in cuneiform characters, and all three are in languages that at the beginning of our century were absolutely unknown. This inscription itself, as a striking monument of unknown import, had been seen by successive generations. Tradition ascribed it, as we learn from Ctesias, through Diodorus, to the fabled Assyrian queen Semiramis. Tradition was quite at fault in this; but it is only recently that knowledge has availed to set it right. The inscription, as is now known, was really written about the year 515 B.C., at the instance of Darius I., King of Persia, some of whose deeds it recounts in the three chief languages of his widely scattered subjects. The man who at actual risk of life and limb copied this wonderful inscription, and through interpreting it became the veritable "father of Assyriology," was the English general Sir Henry Rawlinson. His feat was another British triumph over the same rivals who had competed for the Rosetta Stone; for some French explorers had been sent by their government, some years earlier, expressly to copy this strange record, and had reported that it was impossible to reach the inscription. But British courage did not find it so, and in 1835 Rawlinson scaled the dangerous height and made a paper cast of about half the inscription. Diplomatic duties called him away from the task for some years, but in 1848 he returned to it and completed the copy of all parts of the inscription that have escaped the ravages of time. And now the material was in hand for a new science, which General Rawlinson himself soon, assisted by a host of others, proceeded to elaborate.
