So extraordinary was the degree of accuracy attained by the ancient architects, that it is doubtful if a single building in all London is so correctly and accurately built as was the Great Pyramid sixty centuries ago. The Egyptians were clever enough to fix their site so that the sides of the Pyramid faced exactly north, south, east and west, without any deviation whatsoever. They had some means of measuring whereby they were able to build the lengths of the sides so truly, that there was not half an inch of difference in any one of them. The builder who is able to build four such walls over 750 feet long, without varying them half an inch in all that length, is a king of his profession. Probably there is not a house put up to-day that does not vary considerably more in the length of its small walls. For sheer accuracy in its measurements, the Great Pyramid is one of the most marvellous structures on earth, and the Egyptians were apparently able to do six thousand years ago what we find it difficult to accomplish to-day. The Great Wall of China was built at the sacrifice of hundreds of thousands of lives, and probably thousands of men perished in the building of the Pyramids. Accidents must have been happening all day long. The huge blocks were handled by men who dragged and pushed them to their positions. The labourers were kept hard at it by their taskmasters, whose one thought was to keep up the supply of stone. Mighty blocks weighing many tons must have often slipped and crushed the workers to death. Many of the labourers must have been maimed for life; legs were broken, arms smashed, heads and bodies crushed, as the blocks rolled and swerved in their progress. From inferences from papyri, the great Pyramids were looked upon by the Egyptians as one of their plagues, as a scourge to the land. Men were pressed into the work, were compelled to go on with it. What mattered it to Khufu if his subjects and slaves died, so long as he built a home that would last his shadow-self for ever? We are wont to marvel at the building of the Pyramids, but under it all there must have been great cruelty as well as an incredible skill. Those monuments which to-day are the glory of Egypt, were in the past one of the afflictions of the land. The building of the Great Pyramid entailed the creation of a mighty sloping road, which Herodotus says took 100,000 men ten years to construct. Men swarmed over the desert like ants over a disturbed anthill, making this enormous slope up which to drag and push these gigantic blocks. The centre of the slope was paved with polished stone, so that the blocks would slide easily along, but in spite of this attempt to ease the burden, the moving of the stones must have been a heart-breaking task. As the Pyramid rose, so the road grew higher.
