Khufui, the Kheops of the Greeks, was probably son of Snofrui. He reigned twenty-three years, successfully defended the valuable mines of copper, manganese and turquoise of the Sinaitic peninsula against the Bedouin; restored the temple of Hathor at Dendera; embellished that of Babastis; built a sanctuary to the Isis of the Sphinx; and consecrated there gold, silver and bronze statues of Horus and many other gods. Other Pharaohs had done as much or more; but the Egyptians of later dynasties measured the magnificence of Kheops by the dimensions of his pyramid at Ghizel. The Great Pyramid was called Khuit, the "Horizon," in which Kheops had to be swallowed up, as his father, the sun, was engulfed every evening in the horizon of the west. Of Dadufri, his immediate successor, we can probably say that he reigned eight years; but Khephren, the next son who succeeded to the throne, erected temples and a gigantic pyramid, like his father. He placed it some 394 feet to the south-west of that of Kheops, and called it Uiru the Great. It is much smaller than its neighbour, but at a distance the difference in height disappears. The pyramid of Mykerinos, son and successor of Khephren, was considerably inferior in height, but was built with scrupulous art and refined care. The Fifth dynasty manifested itself in every respect as the sequel and complement of the Fourth. It reckons nine Pharaohs, who reigned for a century and a half, and each of them built pyramids and founded cities, and appear to have ruled gloriously. They maintained, and even increased, the power and splendour of Egypt. But the history of the Memphite Empire unfortunately loses itself in legend and fable, and becomes a blank for several centuries. _VI.--The First Theban Empire_ The principality of the Oleander--Naru--comprised the territory lying between the Nile and the Bahr Yusuf, a district known to the Greeks as the island of Heracleopolis. It, moreover, included the whole basin of the Fayum, on the west of the valley. Attracted by the fertility of the soil, the Pharaohs of the older dynasties had from time to time taken up their residence in Heracleopolis, the capital of the district of the Oleander, and one of them, Snofrui, had built his pyramid at Medum, close to the frontier of the nome. In proportion as the power of the Memphites declined, so did the princes of the Oleander grow more vigorous and enterprising; and When the Memphite kings passed away, these princes succeeded their former masters and eventually sat "upon the throne of Horus."
