Ever since the appearance of Google Maps some use them to measure the
mutual positioning of the Giza pyramids. Because of a shift in the Earth
axis since the time the pyramids were built, such measurements are
misleading. Using the present position of the True North extends the
span of the pyramids from North to South substantially.
In the effort to determine what the position of the True North was at
the time of building, the pyramids themselves furnish a reliable
testimony, I believe. My belief stems from the fact that the pyramids
show incredibly perfect control by their builders over the alignment of
their sides.

Quoting Petrie from "The Pyramids and Temples of Gizeh"
Chap. 13. Positions and Orientation of the Pyramids
.
"Hence, in 4,000 to 6,000 years — the age of the Pyramids by different chronologists — the change of Greenwich latitude would amount to just about 1'.
Thus, as far as observation can lead us, it seems to show a shift of
the earth's axis in longitude 0؛ to a fifth of the extent shown in
longitude 121؛ by the Pyramid orientations; and therefore a change of
the same order, and not improbable in its extent.
.......
[p. 127]Assuming a change of place of the axis amounting to 1' in 1,000 years, ....
Thus the apparent change in the axis of rotation shown by the
orientation of the Pyramids, is of the same order as a change actually
observed.
and: "On the whole, considering the various values of the data, – 5' 40"
± 10" may be taken as a safe statement of the suggested place of the
pole, at the epoch of the Pyramid builders."
The present consensus pegs the Giza pyramids' age at about 4,400 - 4,600
years. By Petrie's estimate of the True North axis changing 1' per
millennium, the pyramids' orientation would then move out of alignment
with the True North by about 4.5' since the time of their building.
.
Let's make the North to South span of the pyramids 1,732.05 cubits, the
value posited by my theory. To do that, we have to rotate the True
North 4'37'' from its present position. This rotation is then in sync
with the estimated age of the pyramids and Petrie's estimated rate of
axial travel.
.
Rotate CCW by the midsides so the N-S span = 7,026,552.425 Survey Units = 1,732.05 cubits = 35,713.1"
.................. our angle of rotation from Petrie's arbitrary North = 1º7'45" =
1.12908817º
Petrie's angle of rotation to the True North of the modern era = 1º12' 22" ± 6"
.
difference = 4'37'' add 56.5" (see below why this value) = 5'33.5" which is in range with Petrie's estimate of 5'40" ± 10"

______________________________________________________________________
East and West sides of G1 = 3 seconds difference in alignment
South side of G1 and North side of G2 = 2 seconds difference
South side of G1 and North and South sides of G2 = three sides within 8 seconds of each other
Five lines are within the narrow range of 22' of each other orthogonally.
.
______________________________________________________
The data on alignments showcases the builders' capacity to make pyramid sides absolutely parallel, whenever they wish.
Based on that observation, it is reasonable to conclude that they
could also make the pyramids absolutely square but did not do so for
some reason.
.
Given Petrie's stated margin of error in measurement of 6 seconds for G1
and 16 seconds for G2, there remains a theoretical chance that
altogether five sides are absolutely parallel or orthogonal to each
other.
.
Either way, these alignments exhibit unprecedented accuracy. To position
massive mantle blocks over long distances with such absolute accuracy
would still present a most difficult challenge in our time even when
using all the means at our disposal.
.
Why then do three of the sides - the northern side of G1; the eastern
and western sides of G2 - diverge slightly albeit noticeably from the
uniform direction?
.
Given the builders' capability to be accurate, I believe that these divergencies are deliberate:
Petrie's stated margin of error for G2 is 16 seconds. After we rotate
Petrie's plan so that its North to South span becomes 1,732.05 cubits,
the western side of G2 reads 16 seconds off the True North (90 degrees in the x,y plane of our scheme).
Therefore, it is possible that the actual error in Petrie's
measurement is that 16 seconds, and that the western side of G2 points
exactly to the True North, as it was at the time of laying out the
pyramids.
Encoding the exact direction of True North in at least one side seems
natural. The other sides can then be used for some other purposes.

Manu: lol, that's a brilliant jab. Loved it. The rest of your post goes
downhill fast. I almost sent your post to Glen's daughter Rebecca to let
her respond to this flaming nonsense you whipped up there.
.
I gave a point-by-point critique of Dash's dissatisfaction with Petrie's
approach. You could have addressed it point-by-point; I guess you leave
that chore to Rebecca.
.
Manu: At first I was mystified where this fervor is coming from. Then
I checked the maximum span on the Giza Plateau Map and it dawned, and I
quote you:
Jiri: My hypothesis was that in doing so, the pyramids' orientation will
shift much closer to true North, and therefore indicate that this span
was truly the builders' intention. . 7,026,552.425 Survey Units =
35,713.1"
Manu: And of course the Dash-map of Giza doesn't show that. I did
all four possible maximum spans based on the two sets of two corners and
you are not even close. No wonder the indignation. Yes, I see shadows
on the wall...I see a dog and a pony, Jiri.
.
What you don't see is that Dash works with the present True North, and I don't. The analysis of Giza for planned design has to take the shifting of the True North into account.
.
Manu > This, all the while, Dash confirmed that his measurements
of the four socket markers matched those of Petrie. I am going to
address your major misconceptions in just a moment, but this is exactly
the issue I raised with your comrade Chiginn: If a theory melts away in
the sun when distances less than error margins are called significant
and, thus, allegedly intentional, then you cannot distinguish it from
any of many that do the same.
.
So, if I get it right, comrade Manu, you don't like the fact that my
theory fits into Petrie's margins of error and, in fact, duplicates his
data. Moreover, you claim that there are many other theories that do the
same. Name one!
.
Yes, there is one other theory that does so partially - Legon's. He has
some pioneering ideas, three of which I incorporated into my theory:
1) The North to South span of the pyramids in cubits equals 1,000 times √3.
2) The eastern side of G2 is 250 times √3 or 433.0127.. cubits westwards from the N-S axis of the Great Pyramid.
3) Derivation of the size of G3 in cubits by a neat construction:
Draw a square 555 cubits per side, with a circle inside of 250 cubits radius.
Draw a container square for the circle with sides rotated 45° to the first square.
Each side of the new square slices off a triangle from the first square
whose hypotenuse equals the diagonal of G3. The resulting pyramid is
201.446 cubits ( 4,153.6 inches) per side, exactly as specified by
Petrie.
.
This brilliant modern era solution for G3 must also be the true
solution, because we find a strong confirmation for it in the Engraving _
it integrates with the engraving and the engraving's Mother Star. As usual, its authors know everything we know. Let's take a look.
