Grotefend was of opinion that the cuneiform system was intended only for engraving, and that some other writing must have been in use for ordinary purposes.[326] He divided the various specimens that had come under his notice into three classes. The first included the Persepolitan inscriptions; the second was to be seen upon the stone recently published by Millin, which he says partly resembles the third Persepolitan and partly the Babylonian bricks;[327] and the third the Babylonian inscriptions, the most important being that published by the East India Company. ‘These are the most complicated,’ and are to be ‘distinguished by the number of the strokes of union and by the eight-rayed star.’ The first class—namely, the Persepolitan—he again subdivided into three kinds, according to the relative complexity of the writing. He considers they represent different languages: the first or simplest is the ‘Zend, which is apparently the Median language’; the second the Parsi, or language of the true Persians; the third ‘perhaps a Persian dialect, perhaps Pehlevi; but in consequence of the absence of prefixes it cannot belong to the Aramean family,’ a reason also that excluded the two others from the same classification. He thought the first system of writing was the Old Assyrian; the second differs from it by having a greater number of oblique and fewer angular wedges; while it differs from the third system by avoiding, like the first, wedges placed diagonally, and by having more wedges that cross each other.[328] He held that all the three systems of Persepolitan are alphabetical and not merely syllabic or ideographic; in the first system he finds words composed of eleven characters, in the second of nine, and in the other of seven. On account of the number of signs required in the second system to compose a word, he concludes that it employs separate letters for long and short vowels; and also to express the combination of a consonant and vowel. He thought the number of letters in its alphabet was about forty, and he observed that the monogram for ‘king’ is always used; neither here nor in the third system is the royal title ever written alphabetically. In the Plate (No. 2, 1815) he gives three short inscriptions: the Xerxes (G, Niebuhr), the Cyrus (Murgab) and the Xerxes on the Vase of Caylus, arranged word for word to show the signs in the three systems that correspond to each other; and he found that the second system corresponds word for word to the first, but that the third differs considerably. In the third system he remarked also that a word could be formed with so few signs that he thought it avoided the use of vowel signs as far as possible, and employed a single character to express the threefold combination of consonant, vowel and consonant; and to that extent he concedes that it may be called syllabic.[329]
