Upon disintegration followed, as a natural consequence, quarrel and disturbance. In the reign of Takelut II., the grandson of Osorkon II., troubles broke out both in the north and in the south. Takelut's eldest son, Osorkon, who was High-Priest of Ammon, and held the government of Thebes and the other provinces of the south, was only able to maintain the integrity of the kingdom by means of perpetual civil wars. Under his successors, Sheshonk III., Pamai, and Sheshonk IV., the revolts became more and more serious. Rival dynasties established themselves at Thebes, Tanis, Memphis, and elsewhere. Ethiopia grew more powerful as Egypt declined, and threatened ere long to establish a preponderating influence over the entire Nile valley. But the Egyptian princes were too jealous of each other to appreciate the danger which threatened them. A very epidemic of decentralization set in; and by the middle of the eighth century, just at the time when Assyria was uniting together and blending into one all the long-divided tribes and nations of Western Asia, Egypt suicidally broke itself up into no fewer than twenty governments! Such a condition of things was, of course, fatal to literature and art. Art, as has been said, "did not so much decline as disappear." After Sheshonk I. no monarch of the line left any building or sculpture of the slightest importance. The very tombs became unpretentious, and merely repeated antique forms without any of the antique spirit. Each Apis, indeed, had, in his turn, his arched tomb cut for him in the solid rock of the Serapeum at Memphis, and was laid to rest in a stone sarcophagus, formed of a single block. A stela, moreover, was in every case inscribed and set up to his memory: but the stelæ were rude memorials, devoid of all artistic taste; the tombs were mere reproductions of old models; and the inscriptions were of the dullest and most prosaic kind. Here is one, as a specimen: "In the year 2, the month Mechir, on the first day of the month, under the reign of King Pimai, the god Apis was carried to his rest in the beautiful region of the west, and was laid in the grave, and deposited in his everlasting house and his eternal abode. He was born in the year 28, in the time of the deceased king, Sheshonk III. His glory was sought for in all places of Lower Egypt. He was found after some months in the city of Hashedabot. He was solemnly introduced into the temple of Phthah, beside his father--the Memphian god Phthah of the south wall--by the high-priest in the temple of Phthah, the great prince of the Mashuash, Petise, the son of the high-priest of Memphis and great prince of the Mashuash, Takelut, and of the princess of royal race, Thes-bast-per, in the year 28, in the month of Paophi, on the first day of the month. The full lifetime of this god amounted to twenty-six years." Such is the historical literature of the period. The only other kind of literature belonging to it which has come down to us, consists
