At any rate, it is pretty clear that the Hittite characters are used like the Egyptian, sometimes as ideographs to express ideas, sometimes phonetically to represent syllables and sounds, sometimes as determinatives to denote the class to which the word belongs to which they are attached. It is probable, moreover, that a word or sound was often expressed by multiplying the characters which expressed the whole or part of it, just as was the case in Egyptian writing in the age of Ramses II. At the same time the number of separate characters used by the Hittites was far less than that employed by the Egyptian scribes. At present not 200 are known to exist, though almost every fresh inscription adds to the list.
The oldest writing material of the Hittites were their plates of metal, on the surface of which the characters were hammered out from behind. The Hittite copy of the treaty with Ramses II. was engraved in this manner on a plate of silver, its centre being occupied with a representation of the god Sutekh embracing the Hittite king, and a short line of hieroglyphs running round him. This central ornamentation, surrounded with a circular band of figures, was in accordance with the usual style of Hittite art. The Egyptian monuments show us what the silver plate was like. It was of rectangular shape, with a ring at the top by which it could be suspended from the wall. If ever the tomb of Ur-Maa Noferu-Ra, the Hittite wife of Ramses, is discovered, it is possible that a Hittite copy of the famous treaty may be found among its contents.
At all events, it is clear that already at this period the Hittites were a literary people. The Egyptian records make mention of a certain Khilip-sira, whose name is compounded with that of Khilip or Aleppo, and describe him as 'a writer of books of the vile Kheta.' Like the Egyptian Pharaoh, the Hittite monarch was accompanied to battle by his scribes. If Kirjath-sepher or 'Book-town,' in the neighbourhood of Hebron, was of Hittite origin, the Hittites would have possessed libraries like the Assyrians, which may yet be dug up. Kirjath-sepher was also called Debir, 'the sanctuary,' and we may therefore conclude that the library was stored in its chief temple, as were the libraries of Babylonia. There was another Debir or Dapur further north, in the vicinity of Kadesh on the Orontes, which is mentioned in the Egyptian inscriptions; and since this was in the land of the Amorites, while Kirjath-sepher is also described as an Amorite town, it is possible that here too the relics of an ancient library may yet be found. We must not forget that in the days of Deborah, 'out of Zebulon,' northward of Megiddo, came 'they that handle the pen of the writer' (Judg. v. 14).
