There were many colossal statues of Memnon in Egypt, but the most remarkable were the two in the Memnonium or palace of Memnon, at Thebes. The largest is of rose-colored granite, and stood in the centre of the principal court; its height was sixty-four feet, and its remains are scattered forty feet around it. Rigaud, one of the French savans, says, "the excavations are still visible where the wedges were placed which divided the monument when it was thrown down by Cambyses." The trunk is broke off at the waist, and the upper part lies prostrate on the back; it measures six feet ten inches over the front of the head, and sixty-two feet round the shoulders. At the entrance of the gate which leads from the second court to the palace, is the famous colossal sounding statue, which, according to Herodotus, Strabo, and Pausanias, uttered a joyful sound when the sun rose, and a mournful one when it set. It is also related that it shed tears, and gave out oracular responses in seven verses, and that these sounds were heard till the fourth century after Christ. These phenomena, attested by many ancient and modern writers, are variously accounted for by the learned, as priestcraft, peculiar construction, escape of rarified air, &c. This statue is in excellent preservation. The head is of rose-colored granite, and the rest of a kind of black stone. Two other colossal statues, about fifty feet high, are seated on the plain. HELIOPOLIS. The name of Heliopolis, or City of the Sun, was given by the Greeks to the Egyptian _City of On_. It was situated a little to the north of Memphis, was one of the largest cities of Egypt during the reign of the Pharaohs, and so adorned with statues as to be esteemed one of the first sacred cities in the kingdom. The temple dedicated to Re, was a magnificent building, having in front an avenue of sphynxes, celebrated in history, and adorned with several obelisks, raised by Sethosis Rameses, B.C. 1900. By means of lakes and canals, the town, though built on an artificial eminence, communicated with the Nile, and during the flourishing ages of the Egyptian monarchy, the priests and scholars acquired and taught the elements of learning within the precincts of its temples. At the time of Strabo who visited this town about A. D. 45, the apartments were still shown in which, four centuries before, Eudoxus and Plato had labored to learn the philosophy of Egypt. Here Joseph and Mary are said to have rested with our Saviour. A miserable village, called _Metarea_, now stands on the site of this once magnificent city. Near the village is the _Pillar of On_, a famous obelisk, supposed to be the oldest monument of the kind existing. Its height is 671/2 feet, and its breadth at the base 6 feet. It is one single shaft of reddish granite (Sienite), and hieroglyphical characters are rudely sculptured upon it. MEMPHIS.
