Warwick writes, 'So tales of Khufu prostituting his wives to pay for his pyramid are not Pyramidology?'

Well, strictly speaking the answer is: no they are not.

Piazzi Smyth, Davidson & Aldersmith, Rutherford, Raymond Capt, John and Morton Edgar, Lemeseurier, as far as I can recall none of these Pyramidologists make mention of this tale or fable.

Pyramidology concerns itself with Bible chronology and mathematical and geodetic secrets written, so to speak, in the Great Pyramid's dimensions.
Unfortunately, in the last few years some Pyramid researchers have found it expedient to lump under the heading 'Pyramidology' anything they deem even the slightest bit 'unorthodox'.
This way they can with the minimum of effort effectively discredit any Pyramid theory they disapprove of.
Useful thing, psychology...
