As we have seen, Niebuhr had perceived that the Persepolitan inscriptions were in three different systems of writing. But it was only after the decipherment of the Persian texts that it was found that the three systems of writing embodied three separate languages, and belonged to three separate countries. As in modern Turkey a governor has to issue an edict in agglutinative Turkish, Semitic Arabic, and Aryan Persian, so too in ancient Persia a king who wished to be understood by all his subjects had to appeal to them in the Aryan language of Persian itself, in the Semitic language of Babylonia and Assyria, and in the agglutinative language of Susiania or Elam. When the second and third systems of writing came to be read it was discovered that the second contained the script and language of Elam--sometimes, but incorrectly, called Scythian, Medic or Protomedic, sometimes, more properly, Amardian or Neo-Susian--while the third was Babylonian. The three capitals of the empire, Persepolis, Susa and Babylon, were thus each of them represented. The number of characters used in Amardian, though large, was limited, and accordingly, with the help of the proper names occurring in the Old Persian texts, a syllabary, or list of characters each expressing a syllable, was soon formed and the work of translation commenced. Westergaard, the Dane, who had already travelled in Persia, and there copied the inscription on the tomb of Darius at Naksh-i-Rustem, led the way in 1845. He was followed by Hincks, de Saulcy, and above all Edwin Norris, the learned Secretary of the Royal Asiatic Society, who published in 1853 the Amardian (or as he called it the 'Scythic') version of the Behistun inscription, with an elaborate translation, commentary, and vocabulary. Further progress, in the study of the language was made by Oppert, whose book _Le Peuple et la Langue des Mèdes_ (1879) is a monument of systematic research. Sayce's decipherment of the inscriptions of Mal-Amir, south-east of Susa, in 1884 (in the Proceedings of the Sixth Oriental Congress), showed that we must look to that part of Susiania for the origin of the Amardian syllabary and dialect. The language was, in fact, one of the agglutinative dialects spoken in Elam, the native language of Susa itself being closely related to it. Unfortunately, however, there is no known language with which the dialects of ancient Elam can be compared, and consequently our knowledge of them hardly extends beyond the help afforded by the trilingual Persian texts.
