Note 43 — THE PROBLEM OF THE GREAT PYRAMID.

It seems to me not improbable that the level was determined by simply flooding (though to a very small depth only, of course) the entire area to be levelled—not only the pavement level, but higher levels as the pyramid was raised layer by layer. By completing the outside of each layer first, an enclosed space capable of receiving the water would be formed (the flooding being required once only for each layer), and when the level had been taken the water could be allowed to run off by the interior passages to the well which Piazzi Smyth considers to be symbolical of the bottomless pit.
