Still, whatever gloomy associations attach to the pyramids in respect of the sufferings caused by their erection, as monuments they must always challenge a certain amount of admiration. A great authority declares: "No one can possibly examine the interior of the Great Pyramid without being struck with astonishment at the wonderful mechanical skill displayed in its construction. The immense blocks of granite brought from Syene, a distance of five hundred miles, polished like glass, and so fitted that the joints can scarcely be detected! Nothing can be more wonderful than the extraordinary amount of knowledge displayed in the construction of the discharging chambers over the roof of the principal apartment, in the alignment of the sloping galleries, in the provision of the ventilating shafts, and in all the wonderful contrivances of the structure. All these, too, are carried out with such precision that, notwithstanding the immense superincumbent weight, no settlement in any part can be detected to an appreciable fraction of an inch. Nothing more perfect mechanically has ever been erected since that time."[8] [Illustration: VIEW OF THE GREAT AND SECOND PYRAMIDS.] The architectural effect of the two greatest of the pyramids is certainly magnificent. They do not greatly impress the beholder at first sight, for a pyramid, by the very law of its formation, never looks as large as it is--it slopes away from the eye in every direction, and eludes rather than courts observation. But as the spectator gazes, as he prolongs his examination and inspection, the pyramids gain upon him, their impressiveness increases. By the vastness of their mass, by the impression of solidity and durability which they produce, partly also, perhaps, by the symmetry and harmony of their lines and their perfect simplicity and freedom from ornament, they convey to the beholder a sense of grandeur and majesty, they produce within him a feeling of astonishment and awe, such as is scarcely caused by any other of the erections of man. In all ages travellers have felt and expressed the warmest admiration for them. They impressed Herodotus as no works that he had seen elsewhere, except, perhaps, the Babylonian. They astonished Germanicus, familiar as he was with the great constructions of Rome. They furnished Napoleon with the telling phrase, "Soldiers, forty centuries look down upon you from the top of the pyramids." Greece and Rome reckoned them among the Seven Wonders of the world. Moderns have doubted whether they could really be the work of human hands. If they possess only one of the elements of architectural excellence, they possess that element to so great an extent that in respect of it they are unsurpassed, and probably unsurpassable.
