Khafre, the next king but one after Khufu, built the second pyramid, which is almost as high as that of Khufu, being 447½ feet, but measures on the sides but 690½ feet. Within and under the pyramids are the tomb chambers. Khafre also carved out of the native rock, not far from these two pyramids, the great Sphinx, the head of which bore a portrait of himself. From the top of the head to the pavement under the paws is 66 feet; the breadth of the face is 13 feet 8 inches, and the other parts are in proportion. Near the Sphinx stands a temple, built of polished granite, which is connected by an underground passage with the pyramid of Khafre. All these are silent but eloquent witnesses to the skill of the Egyptians of this period in stone work, and to the absolute power of the Pharaoh; (see Figs. 5 and 6). Menkaure, the next king, constructed a smaller pyramid, the side of its base being 356½ feet and its height 204 (originally 219) feet. Either his power was less or the resources of the kingdom were becoming exhausted. Though the pyramidal form of tombs continued for several centuries, no others were ever built that approached these in size. The fifth dynasty was founded by a priest of On. During its rule the power of the king was not so absolute, and a powerful nobility began to develop. These nobles had themselves buried in tombs of the old mastaba type, and adorned the walls with pictures of the industries which were carried on upon their country estates. One of the most famous of these is the tomb of a certain Ti, from the pictures in which much has been learned of the various industries of ancient Egypt. By the time of the sixth dynasty a strong nobility had been developed in the different nomes, so that the monarchy was thoroughly feudal. The absolute power that the kings of the first four dynasties had exercised had passed away. During the sixth dynasty the conquest of northern Nubia was begun, an expedition was sent to the far-away land of Punt, a country far to the south. It was probably the region on both sides of the straits of Bab-el-Mandeb, comprising southwestern Arabia and Somaliland. An expedition was also sent over sea to Palestine, to chastise the inhabitants of the southern portion of that country for invading Egypt. The capital of Egypt during the whole of the Old Kingdom was Memphis. The city thus gained a prominence which made it ever afterward famous. In early times it had been called the White Wall, but after the sixth dynasty it was called _Men-nofer_, of which Memphis (Hosea 9:6) is a corruption. It is in the Old Testament more often called Noph, a corruption of the last part of the name. (See Isa. 19:13; Jer. 2:16; 44:1; 46:14, 19; Ezek. 30:13, 16.)
