(2) _Peiser._--In 1892 Dr. Peiser, then of Breslau University, published his book on the Hittite inscriptions, in which he essayed another method of decipherment. Layard had found four Hittite seals in the palace of Sennacherib at Nineveh. Peiser inferred that these must be seals of four Hittite kings mentioned in the inscriptions of that time, and proceeded to assign each seal to the name of a known Hittite king, and interpret the signs on the seal by the name of that king as spelled out in the cuneiform characters of the Assyrian inscriptions. Having obtained in this way tentative values for several signs, he proceeded by inference to guess at other signs, and so tentatively read some inscriptions. (3) _Jensen._--Prof. Jensen, of Marburg, wrote in that same year an unfavorable review of Peiser’s work. When reading the proofs of his review he added a postscript to say that he believed he had himself discovered the key to Hittite. Two years later, 1894, he published in the Journal of the German Oriental Society his method of solving the problem. Jensen’s starting-point was gained from inscriptions from Jerabis, the site of ancient Carchemish, Hamath, and other places. He inferred that a certain sign was the determinative for city, and that the names preceding this sign were names of places. Gaining in this way some values for signs, he read the names of some kings. He found that these names had nominatives ending in _s_ and accusative cases ending in _m_; he accordingly leaped to the conclusion that the Hittite language was a member of the Indo-European group of languages, as this is the only known group of tongues in which this phenomenon occurs. This inference later research has in part confirmed. Jensen, however, went further and endeavored to show that the Hittites were the ancestors of the Armenians of later time. This theory led to the publication in 1898 of his book, _Hittiter und Armenier_. Of the correctness of this view he has not been able to convince other scholars. By this time Jensen and others had begun to see that the Mitannians and the Hittites were kindred peoples and worshiped the same gods. It is now recognized that Jensen correctly ascertained the value of some signs, though many of his guesses, like those of his predecessors, have proved incorrect.
