Thothmes III., the greatest of Egyptian monarchs, and brother of Hatasu, erected four obelisks at Heliopolis, and probably others in different parts of Egypt. These four have been named "The Needles"--two of them "Pharaoh's Needles," and two "Cleopatra's Needles." The former pair were removed from Heliopolis to Alexandria by Constantine the Great. Thence one was taken, according to some Egyptologists, to Constantinople, where it now stands at the Atmeidan. It is only fifty feet high, but it is thought that the lower part has been broken off, and that the part remaining is only the upper half of the original obelisk. [Illustration: THE OBELISK OF THOTHMES III., AT CONSTANTINOPLE.] The other was conveyed to Rome, and now stands in front of the church of St. John Lateran, and from its great magnitude it is regarded as "the giant of the obelisk family." Amenophis II., of the XVIIIth dynasty, set up a small obelisk, of Syenite granite, about nine feet high. It was found amid the ruins of a village of the Thebaid, and presented to the late Duke of Northumberland, then Lord Prudhoe. Amenophis III., of the XVIIIth dynasty, erected two obelisks in front of his temple at Karnak; but the temple is in ruins, and the obelisks have entirely disappeared. Seti I. set up two; one, known as the Flaminian obelisk, now stands at the Porta del Popolo, Rome, and the other at Trinita de Monti, in the same city. Rameses II. was, next to Thothmes III., the mightiest king of Egypt; and in the erection of obelisks he surpassed all other monarchs. He set up two obelisks before the temple of Luxor; one is still standing, but the other was transported to Paris about forty years ago. The latter is seventy-six feet high, and seven and a-half feet higher than the London one. Two obelisks, bearing the name of Rameses II., are at Rome, one in front of the Pantheon, the other on the Cœlian Hill. Ten obelisks, the work of the same monarch, lie buried at Tanis, the ancient Zoan. Menephtah, son and successor of Rameses, set up the obelisk which now stands in front of St. Peter's, Rome. It is about ninety feet high, and as regards magnitude is the third obelisk in the world. Psammeticus I., of the XXVIth dynasty, set up an obelisk at Heliopolis in the year 665 B.C. It now stands at Rome on the Monte Citorio. Psammeticus II., about the same time that Solomon's temple was destroyed, erected an obelisk which now stands at Rome, on the back of an elephant. Nectanebo I. made two small obelisks of black basalt. They are now in the British Museum, and, according to Dr. Birch, were dedicated to Thoth, the Egyptian god of letters. They were found at Cairo, built into the walls of some houses. One was used as a door-sill, the other as a window-sill. They came into possession of the English when the French in Egypt capitulated to the British, and were presented to the British Museum by King George III. in 1801. They are only eight feet high.
