But the deciphering of the second and third languages had yet to be attacked. In 1844 Westergaard, working on the lines of Grotefend, attacked the second language. He selected the names of Darius, Hystaspes, and Xerxes, and compared them with their equivalents in the Persian texts. By this means he discovered a number of signs and by their aid attempted to spell out the syllables or words. Judging the writing to be partly alphabetic and partly syllabic, he gave the name Median to the language. Morris, who had Rawlinson's copy of the second transcription of the Behistun text to work upon, deciphered nearly all of it. Shortly after this the language was named Susian. The deciphering of the third of the three languages found at Persepolis was attacked by Löwenstern, and by the Rev. Edward Hinks, an Irish clergyman. This language was Assyrian purely. Hinks was fearful of making blunders, and whilst he was engaged in assuring himself that every step he took was not a false one, Longpérier, published in 1847 a translation of the entire text. He was only able to read it by analogy with the other texts; he could not provide the forms of the Assyrian words themselves. But Rawlinson once more came to the aid of the study, and it was shown that a large number of signs were ideographic. This paved the way for a band of others who by their united efforts succeeded in unravelling the complicated script. Origin of Cuneiform This peculiar system of writing originated in Babylonia, its inventors being the Sumerian or non-Semitic people who inhabited that country before its settlement by the Babylonians. It was developed from picture-writing, and indeed some of the more highly significant of the pictorial signs can still be faintly traced in their cuneiform equivalents. This early picture-writing was inscribed on stone, but eventually soft clay was adopted as a medium for the script, and it was found that straight lines impressed upon this medium tended to the shape of a wedge. The pictures therefore lost their original character and came to be mere conventional groups of wedges. The plural was represented by doubling the sign, and a term might be intensified by the addition of a certain stroke: thus the sign for 'house,' if four small strokes were added to it, would mean 'great house,' and so forth. The script was badly suited to the Assyrian language, as it had not been originally designed for a Semitic tongue. It consists of simple syllables made up of a vowel by itself or a vowel and a consonant, ideograms or signs which express an entire word, and closed syllables such as _bit_ or _bal_. Again, many of the signs have more than one syllabic value, and they may be used as ideograms as well as phonetically. As in the Egyptian script, determinatives are employed to indicate the class to which the word belongs: thus, a certain sign is placed before the names of persons, another before territorial names, and a third before the names of gods and sacred beings.
