The Pyramids of Gizeh
Villa of an Egyptian Noble
The Egyptians excelled in architecture, and the greatest of their buildings were the pyramids. As to whether or not there was much invention devoted to those works, it is virtually impossible now to know. The probability seems to be that they could not have been produced without the promptings of the inventor, but that the progress was a slow and gradual march. It seems that there was a long series of many small inventions that made short steps, and not a few basic inventions that proceeded by great leaps.
Gallery in the Great Pyramid
The Great Gallery is also of curious construction. Extending for a distance of one hundred and fifty feet, and rising at an angle of 26° 18', it has a width of five feet at the base and a height of above thirty feet. The side walls are formed of seven layers of stone, each projecting a few inches over that below it. The gallery thus gradually contracts towards the top, which has a width of four feet only, and is covered in with stones that reach across it, and rest on the walls at either side. The exact object of so lofty a gallery has not been ascertained; but it must have helped to keep the air of the interior pure and sweet, by increasing the space through which it had to circulate.
