The only other known usage of this ancient Egyptian
system is in the construction of the Great Pyramid, where both the
Royal Cubit
and
the
Scientific Cubit are evidenced. For example:
The
Great Pyramid is the only pyramid to utilize an upward sloping passage
system (all the others have simple passages which slope downward to a
chamber below ground level). This terminated in a "King's Chamber" which
has dimensions of 10.00 Royal Cubits Wide, 20.00 Royal Cubits Long, 5.00
radical 5 Royal Cubits High, giving a Cubit Diagonal distance of 25.00
Royal Cubits. The chamber walls are made of highly smoothed granite,
giving accuracies to better than one part per thousand.
The
width of the "King's Chamber" is also 365.2 scientific-inches
divided by the square-root of Pi.
Prior
to entering the "King's Chamber", there is an ante chamber
which has a length such that a circle inscribed from wall to wall, and
touching the floor, has a circumference of 365.2 scientific inches.
The
distance from the center of the ante chamber, to the far wall of the
King's chamber, is 365.2 scientific inches.
Inside
the "King's Chamber" there exists a hollowed out granite block
sufficiently large that it had to have been placed there during the course
of construction (it doesn't fit through the entryway). This so-called
'sarcophagus' is highly polished on its interior and exterior surfaces,
and is correlated to the dimensions of the "King's Chamber" itself.
Specifically, the length + width + height of the "King's Chamber" is
5.00 times greater than the length + width + height of the 'sarcophagus'.
Further, the width of the "King's Chamber," when the length
of the 'sarcophagus' is subtracted out, gives a distance which when used
for the diameter of a circle gives a circle of 365.2 scientific inches
in circumference.
In
addition to the upward-sloping passageway, there is also a downward-sloping
passageway of equal slope, being about 26 degrees-18 minutes-9 seconds.
Using these two slopes as the sides of an angle, one can measure off
the length of the "King's Chamber" (20 Royal Cubits) on one
leg of the angle, and the same length along the other leg. The distance
then separating the two ends of the legs of the angle is 365.2 scientific
inches.
Many other example of the usage of both systems of measurement can be
found in the Great Pyramid, but in no other Egyptian structures.
