It is possible, therefore, that some of the Hittite monuments of Asia Minor are the work, not of the Hittites themselves, but of the native populations whom they had civilised and instructed. It may be that this is the case at Ibreez, where the faces of the god and his worshipper have Jewish features very unlike those found on monuments of purely Hittite origin. But apart from such instances, where the monument is due to Hittite influence rather than to Hittite artists, it is certain that most of the Hittite memorials of Asia Minor are the productions of the Hittites themselves. This is proved by the hieroglyphs which are attached to them, as well as by the uniform type of feature and dress which prevails from Carchemish to the Ægean. It is impossible to explain such an uniformity, and still more the extraordinary resemblance between the characters engraved at Karabel, or on Mount Sipylos, and those which meet us in the inscriptions of Hamath and Carchemish, except on the supposition that the monuments were executed by men who belonged to the same race and spoke the same language. Wherever Hittite inscriptions occur, we find in them the same combinations of hieroglyphs as well as the use of the same characters to denote grammatical suffixes. We may, then, rest satisfied with the conclusion that the existence of a Hittite empire extending into Asia Minor is certified, not only by the records of ancient Egypt, but also by Hittite monuments which still exist. In the days of Ramses II., when the children of Israel were groaning under the tasks allotted to them, the enemies of their oppressors were already exercising a power and a domination which rivalled that of Egypt. The Egyptian monarch soon learned to his cost that the Hittite prince was as 'great' a king as himself, and could summon to his aid the inhabitants of the unknown north. Pharaoh's claim to sovereignty was disputed by adversaries as powerful as the ruler of Egypt, if indeed not more powerful, and there was always a refuge among them for those who were oppressed by the Egyptian king.
