Amenophis IV., the son of Amenophis III., was educated in the faith of his mother, and after his accession to the throne endeavoured to impose the new creed upon his unwilling subjects. The powerful priesthood of Thebes withstood him for a while, but at last he assumed the name of Khu-n-Aten, 'the refulgence of the solar disk,' and quitting Thebes and its ancient temples he built himself a new capital dedicated to the new divinity. It stood on the eastern bank of the Nile, to the north of Assiout, and its long line of ruins is now known to the natives under the name of Tel el-Amarna. The city was filled with the adherents of the new creed, and their tombs are yet to be found in the cliffs that enclose the desert on the east. Its existence, however, was of no long duration. After the death of Khu-n-Aten, 'the heretic king,' his throne was occupied by one or two princes who had embraced his faith; but their reigns were brief, and they were succeeded by a monarch who returned once more to the religion of his forefathers. The capital of Khu-n-Aten was deserted, and the objects found upon its site show that it was never again inhabited. Among its ruins a discovery has recently been made which casts an unexpected light upon the history of the Oriental world in the century before the Exodus. A large collection of clay tablets has been found, similar to those disinterred from the mounds of Nineveh and Babylonia, and like the latter inscribed in cuneiform characters and in the Assyro-Babylonian language. They consist for the most part of letters and despatches sent to Khu-n-Aten and his father, Amenophis III., by the governors and rulers of Palestine, Syria, Mesopotamia and Babylonia, and they prove that at that time Babylonian was the international language, and the complicated cuneiform system of writing the common means of intercourse, of the educated world. Many of them were transferred by Khu-n-Aten from the royal archives of Thebes to his new city at Tel el-Amarna; the rest were received and stored up after the new city had been built. We learn from them that the Hittites were already pressing southward, and were causing serious alarm to the governors and allies of the Egyptian king. One of the tablets is a despatch from Northern Syria, praying the Egyptian monarch to send assistance against them as soon as possible. The 'heresy' of Khu-n-Aten brought trouble and disunion into Egypt, and his immediate successors seem to have been forced to retire from Syria. So far from being able to aid their allies, the Egyptian generals found themselves no match for the Hittite armies. Ramses I., the founder of the Nineteenth Dynasty, was compelled to conclude a treaty, defensive and offensive, with the Hittite king Saplel, and thus to recognise that Hittite power was on an equality with that of Egypt.
