He is good enough to begin the account of his original discoveries by a reference to the previous labours of Grotefend, of which he had a very poor opinion. He has seen the analysis of Grotefend’s system given by Tychsen in the ‘Göttingen Gazette’ of September 1802, and the Essay of De Sacy, written in the following year. These publications, he says, produced little impression at the time, and they were farther discredited by Grotefend’s own contribution to Heeren, in 1805.[364] None of the papers since contributed by Grotefend to periodical literature have shown any improvement upon his earliest writings, and St. Martin lays it down that the contents of the inscriptions are rightly regarded as still wholly unknown. But in addition to this unfavourable opinion, which was shared also by De Sacy, he brings charges of his own against Grotefend’s system that are wholly without foundation. He accuses him of frequently varying the values he assigned to the characters, whereas it was in consequence of the extreme tenacity with which he clung to the values he originally assigned that his progress was in great measure arrested. St. Martin says Grotefend attributed five or six entirely different values to the same character, and that he considered that each character is susceptible of assuming a variety of different forms, both statements being equally without foundation.[365] He affects to regard the corrections introduced into the texts by Grotefend—which is one of his most valuable services—as purely arbitrary, and he professes to believe that interpretations based upon these emendations can inspire no confidence, and can only be regarded as an exercise of the imagination. He was surprised to find that his own interpretations, which he reached by ‘proceeding in an entirely different way,’ should have conducted, so far as they went, to precisely the same result: and he will not dispute that Grotefend is entitled to the priority of merit in detecting the royal names.[366] It does not appear that St. Martin got any farther himself, and we may be permitted to doubt whether he would have accomplished even this but for the labours of the predecessor he is so careful to disparage. When we come to inquire into ‘the entirely different way’ followed by St. Martin we find that in fact it is precisely the same as that with which we are already familiar. He worked on the same two inscriptions, the B and G of Niebuhr; he treats us over again to the analogy of the Sassanian inscriptions: the well-known phrase ‘king of kings’; the genitive suffix; the position of the royal names; the evident relationship of father and son, and so on. Our original investigator continues to carry us over all the old ground. He is struck by the similarity of the wedges in the word for ‘king’ and in one of the royal names; he is guided by the Zend _khsheio_ to the cuneiform words for ‘king’ and ‘Xerxes,’ and he tells us how dexterously he proceeded
