But this was practically the end of Grotefend's discoveries. Burnouf, by a careful study of Persian geographical names, managed to decipher a large number of the characters of the Persian alphabet, and Professor Lassen of Bonn, by similar means, achieved a like end. These two independent achievements raised a fierce controversy as to priority of discovery, but Lassen's system was the more perfect, as he found out that the ancient Persian signs were not entirely alphabetic but were partially syllabic--that is, that certain signs represented syllables instead of letters. This meant that Grotefend's system, which had been almost vowelless, was now to a great extent filled in with the necessary vowels. Rawlinson At this juncture a certain Major Henry Rawlinson, a servant of the East India Company, with a good knowledge of Persian, went to Persia for the purpose of assisting to organize the native army there. He was far away from books, and when he began to copy certain cuneiform texts it was because of deep personal interest. He was quite unaware of the strenuous toil which had been lavished upon them in Europe and worked quite independently of all assistance. The strange thing is that he laboured almost on the same lines as Grotefend had done. He saw almost at once that he had three languages to deal with, and being a man of great natural gifts he soon grouped the signs in a correct manner. Strangely enough he applied the very same names--those of Hystaspes, Darius, and Xerxes--to the texts as Grotefend had done, and found them answer in the same manner. Turning his attention to the inscription of Darius at Behistun, high up in the face of the living wall of rock there, Rawlinson succeeded in copying part of it at great personal risk. In 1838 he forwarded his translation of the first two paragraphs of the Persian text, containing the genealogy of Darius, to the Royal Asiatic Society of London. The feat made a tremendous sensation, and he was supplied with all the principal works on the subject and much correspondence from European scholars. He was, however, patience personified, and would not publish a work he had written on the subject because he thought it better to wait until he had verified his conclusions and perhaps made fresh discoveries. But in 1840 he was despatched to Afghanistan on a political mission and did not return to Bagdad for three years, and it was not until 1846 that he published a series of memoirs in the _Journal_ of the Royal Asiatic Society, in which he gave to the world a translation of the Persian text at Behistun. It was a marvellous achievement, for, unlike those who had been labouring on the subject in Europe, he was ignorant of the languages allied to Persian, yet he had surpassed all other scholars in his results.
