The New York Obelisk: Cleopatra's Needle

Egypt is undoubtedly in every respect a land of wonders. At the most remote period of its history we observe that it was already in such an advanced state of civilization, as would appear to us to be wholly incompatible with its venerable age. When Greece first began to issue from its times of heroes and demi-gods and advance on a path of civilization, Egypt had already for at least twenty centuries possessed everything that enlightened Greece could boast of. The first objects among the many wonders that still remain in Egypt to catch the eye of a traveler, are the grand monuments set up in honor of various divinities or as proud guide-posts for future generations. Among these obelisks and pyramids rank first. We marvel at the enormous stones which our modern steam-engines would lift with difficulty, yet which the ancient Egyptians quarried, transported, and erected in their proper places, not only setting them on the ground, but even lifting them some hundred feet, as in the case of the Pyramids. We look upon the greater number of obelisks, each made of one unbroken piece of stone, and are forced to admire the workmanship and engineering skill which they exhibit. We may endeavor to grasp this wonderful achievement, but must continually ask: how was it done, and how was it possible to do so at that time, when even now with all our many inventions and contrivances we should perhaps fail. Unfortunately we receive no definite answer. It is so long ago since the Egyptian stone-cutters plied their chisels and the engineers built their machines, and no papyrus or inscription tells us directly how the work was accomplished. A relic of indomitable labor and uncompleted work still lies in the quarry at Assuan. It is an obelisk of 95 feet still cleaving on its fourth side to the native rock. This may throw some light on the mystery. We notice the nicety and precision with which the stone-cutter went to work in hewing out and polishing the monument. His art was one that had been brought to the highest state of perfection in Egypt; and no wonder, for in a country where timber was scarce and hardly one tree was suitable for wood-work, men had to fall back on their natural supply which the mountains rising on both sides of the valley yielded. Stone was there in abundance. Hence from the earliest times of Egyptian history the stone-cutter receives a prominent place. The implements he employed must have had a wonderful degree of hardness to chip and polish the tenacious rock of Syene. With regard to the quarrying of the rock, that is, how, after having selected a properly-sized piece of rock without a flaw and having carefully marked it, the stone-cutters were able to detach 50-100 feet of it without a breakthat has given rise to many conjectures. Belzoni held, that after a groove of about two inches had been cut along the line, the blow of some machine must have separated the pieces of rock, as glass when cut by a diamond. Others believe that a saw was employed to sever the rock. Sir J. F. Herschel prefers to accept the theory that the separation of the rocks was caused by fire, a method still employed in India. He calls attention to the fact, that after the workmen there have cut a groove into the rock they kindle a small fire on top of this line, and that after the rock is thoroughly heated they suddenly pour cold water on it, causing the rock to split with a clean fracture. It is, however, more probable that the Egyptians made use of wooden wedges to accomplish their purpose. We frequently find not only grooves in the rock but also wedge-holes inside these grooves. Wedges with their slow and steady pressure would insure a good fracture. Possibly, as Wilkinson surmises, the grooves themselves may have carried water to the wooden wedges which, being kept continually moist and thereby expanding, would have caused the rock to split. The saw was undoubtedly used for the last cutting to separate the piece from the native rock.
