of the Layout of the Great Giza Pyramids
The geodetic survey of
the three great Giza Pyramids, published in 1883, by Sir William
Flinders Petrie, has since been a perennial subject of analysis for
geometric and numeric significance. To show that
the three great pyramids are parts of one and the same plan, there
to generate their layout from pure
ideas, a clean slate.
Indeed, Giza abounds with inspiring
relationships of varied accuracy, but, to safely pin ideas on
the original designers, those have to prove their
mettle by integrating into a system and being compellingly
accurate. Why should we believe the builders had been capable of such accuracy to begin
with? -- There is a
well known examples showcasing the uncanny ability of Giza builders for
accuracy, thus setting a standard for evaluating our own
reconstructions as would-be copies of the
original Egyptian plans.
problem is that various elegant elements of design discovered
Giza by various researchers seem a
foot or so out. Nevertheless, on a drawing board
35x35 inches, such ideas shall look absolutely accurate because their
inaccuracy is diminished thousandfold. The Giza designers had been well
aware of this convergence of multiple ideas. It adds greatly to the
puzzle quality, but has misled
many authors into wishful thinking.
Legon's reconstruction of the Giza plan, however,
stands out among other works in the field, for it works remarkably well along the east-west
axis. It is impressively accurate for three major
lines, the east and west sides of the
Second Pyramid, and the west side of the Third Pyramid. In contrast, the south side of the Second Pyramidc is 1.5
inches, or 40 millimeters off Petrie's plan, the north is 1 inch, or 25 millimeters off.
So, why did
builders not achieve comparable accuracy in keeping with their
plan along this N-S axis? We have seen that it was in their
power. Perhaps, Legon's theory is too simple.
Be it as it may, Legon is right
stating that axial spacing between the pyramids
roots of the first five prime numbers, 1, 2, 3,5, 7, given in 250 x,
and 1000 x multiples of cubits. In fact, his reconstruction comes
fairly close to Petrie's plan, and had I been
familiar with it earlier, I might have accepted it, albeit
reluctantly. Legon's interpretation puts the ancient builders on a
level everybody expects - they had a simple plan,
and executed it really well, although somewhat
For this reason, I find it hard to grasp, why Legon's
does not command more attention and approval from
the academy. His only sin is making plain the Egyptian knowledge
of square roots and Pi to several digits. That's it..
If Legon's theory smacks of heresy to the mainstream, what
reception is in store for a theory like mine? It presents a sophisticated exact construction
which duplicates Petrie's
measurements (stated by Petrie to the tenth of an inch) with superb exactitude. The Golden Section, square roots, and Pi
imbue it with a most appropriate spirit for sacred
I see our
scepsis prone academy not treating this design kindly, because it is,
frankly, too deeply thought out. After all, the Fourth
Dynasty arrived almost on the heels of hunter-gatherers. How could
its architects reach such sophistication so quickly? In short, if
pressured, the academy might embrace Legon's theory, as the simpler (although incaccurate)
As a body, the academy scoffs at
very idea of a unified plan for all three pyramids. With so much smoke
is the burning question:
Was there a GRAND PLAN for the three great Giza pyramids?
A diehard skeptic will try to nip the idea in the bud and say that
even if Giza's groundplan could
be cleanly translated into a meaningful
geometric design, it
would mean nothing. Such prejudice seems to actually dominate
the academic establishment. Anybody, who dares
think otherwise is automatically discounted under various
Yet, the true
solution, due to being both accurate and meaningful, will tower above others. Accordingly, the faults of my reconstruction are so miniscule and so insignificant that rather than being faults, they are manifestations of precision.
The North-South distance between the pyramids is 35,713.2 inches.
To show a fault of 1/100"

a computer screen, we need to assign at least a pixel to it. Then the
total resolution has to be 3,571,320 by 3,571,310 pixels to

inch in both directions. The fault
of 1/100" would show on this screen as 1/100,000".
Faults in my reconstruction range between 0.0014" to 0.035". Considering the size of Giza,
it can safely be said that the reconstruction is microscopically precise. Consequently, it is in all likelihood the same as the
original plan. By the same token, solutions, which draw over Google's satellite view of Giza need not apply.
is due to Petrie's
Although academic opinions suggest that
measurements of the Great Pyramid by Cole supersede those by Petrie, I
am confident in the belief that Petrie did a better job than
by the virtue of choosing the better method for the
circumstances. I believe in what looks so perfect through the
prism of my own reconstruction; My results
are an order of magnitude nearer to Petrie's actual numbers than to his
margins of error. It is, as if he were given the original plan to convert distances to the nearest tenth of an inch. In any
case, Petrie's Giza work had to be a superbly accurate mensuration of
superbly accurate objects. That would explain why there is
massive agreement between my
reconstruction and Petrie's plan, and none with

John Legon makes a strong case that

extends to five decimals of the square root of

In this manner,
a strong case is made for the exact length
of the cubit used in planning Giza's layout. It is also
clear that the reconstruction would not work on any other scale, for
then it could not convert to the above-mentioned exacting numbers.
Petrie's measurements at Giza,
and inside the Great Pyramid had produced slightly differing values for the cubit. He settled for an average of 20.62" (inch) per cubit. This reconstruction's cubit
is 20.6190...", only 1/1000" off Petrie's value.

Petrie's Giza Ground Plan From Scratch
Foundation - Classic Geometry

Section, showcasing the quickest, simplest construction of the regular 5-pointed
star. The strange thing is that there is no mention of this technique anywhere on the internet, so it is definitely obscure. As for myself, I learned it
from the Nazca-monkey! That is not to say that this construction is unknown in modern era
(post Egyptian), but it is mildly surprizing that efficiency of
construction is not a greater concern nowadays.

and takes ten

within ¼ millimeter of Petrie's plan. If this sounds
baffling, check it out in action later. I
thought that I should bring this to the reader's attention now to
emphasize the strong bond between this pattern, and the
On step eleven, we have a choice of three points (D, 1,2) from which to draw a
circle. The one shown above centers in "D" and passes through "1" and "2".
Then the other two (circled) points at which the circle crosses the 36
degree angle lines mark two more tips of a 5-pointed
Lines from those tips drawn through "D" then complete the star. And that's it! (In trade terms, the simplicity
of the construction is 13).
The other choices use the same circle drawn from either "1"
or "2". This diagram shows the circle centered in "1",

Altogether, there are five procedures, each projecting the same initial pyramid. Only
generic, the others are firmly connected to the 13-Step construction. The
design's nature is itself a strong hint at the
designers' familiarity with the entire spectrum of
If the designers had known only the single generic way to project the

Petrie's Giza Ground Plan From Scratch
Building Upon the Geometric Founfation
Follow the Illusions
like the ubiquitous instruction guides for "dummies", the Giza
designers provide easy to follow guidance in the form
clues. The Giza layout is uniquely expressive by being really close to
an unprecedented number of elegant ideas, which might have dictated its
design. One by one, these turn out to be inaccurate, mere
illusions. Yet, illusions are part of reality, at least at Giza. Like
in stereoscopic vision, illusions, the differing views of the same
thing focus into the real thing. All one has to do is just get on
track. The first exact reconstruction of one of the pyramids in
the context of the Pyramid Square is the Great Pyramid. The
process is remarkably short.
Illusion #1 - Draw
a circle from the southeastern (bottom right) corner of Giza's containing
rectangle, such that it touches the
circumcircle. This circle creates an illusion that it also touches the southeastern corner of G3 (Menkaure).
Illusion #2 - The same circle
appears to be of the same size as the "Transmission-circle" (e-circle) in the diagram below, whose radius is the golden
diagonal from the pyramid's NW corner, marked as "a" in diag.5.
So, we copy the Transmission-circle to the bottom right corner of
the containing rectangle, as well. When concentric, the two circles
merge into a single circle on this scale.
Illusion #3 - From the center of the interim pyramid, draw the complementary circle, which touches the Transmission-circle, then copy it to the southwestern (bottom left) corner of the Pyramid Square. It gives the illusion of touching G3 from the other side (diag. above). This is certainly a startling effect,
albeit up close it is not all
So, we have
two pairs of alike circles
which look the same from
high up above Giza. Without viewing
things in the context of Pyramid Square, we would be deprived of
this interesting observation. I wonder how many researchers may
have observed the same illusion of the big circle from
the southeastern corner of Giza's enclosing rectangle touching two
pyramids, only to drop it as useless.

one side of G3. On the basis of this assumption, the pyramid
is completed around the axis.

operation which makes the reconstruction of the Great Pyramid

versions of the original which create a channel of parallel, or concentric lines, often, the
solution is simplicity itself - a single step:

obvious improvement over "b"..

same procedure using the circle 'c' (below), which is
tangential to the circumcircle
of the initial Great Pyramid, produces the SE corner of the prototype G3 - version # 2.
It is 3.68 inches to the west of the original, and half-way between a and c.
The symbolic language of coincidences around
the transmission circle guides us
along the trail. While I used to start the reconstruction from a
golden rectangle without the precursory steps, I was left wondering: Why the transmission circle? Then
I saw it (its radius) in the context of the '13-Step' construction (diagram below).
Point '2' is a big point in the original 13-Step-star's construction. The radius 3-4 duplicates the golden circle's radius from the same construction. The segment 1-2-3-4 was used in the construction of the initial G1. It is the Transmission-circle's radius. The design involves classy geometry.
An Accurate Reconstruction of the SE corner of G3
With the Great Pyramid duplicated, it is
now possible to do the following:.

SE corner of G3, Menkaure.
Lines '1' and '2' belong to
the pyramid as given by Petrie. Lines 'a' and 'b' are the transmission circle, and
the Great Pyramid's circumcircle. Going down the
middle again, the axis of the channel between them is 0.13
inch, or 3.1
millimeters to the east of the pyramid corner as given by Petrie.

construction, without resort to units.

that measuring one exact cubit eastwards from the tangential
circle, like in the diagram above, comes 0.25 millimeter closer, at 2.85 millimeters east of the SE corner of Menkaure. I
should mention that Legon
could follow this procedure as well, and get almost as good a result.

attention; the two letters I had sent him are near the end

also implies that counting westwards from the east side of the
Second Pyramid, 250√2

the west side of the Third Pyramid.
This formula works the best, as it locates the west

worked with, unfortunately.
So, far we counted four accurate ways to deploy an exact formula containing 250√2 towards location of the SW corner of the Third Pyramid.
As to its SE corner, earlier it was located by the means of the "magic number" 113, hence another exact number.
Again, there is some consistency
So which solution should we use? The fact is that there are at once
four accurate solutions for the
west side of the Third Pyramid, or its SW corner. All four
are accurate - since Petrie's points come with a ±
radius, those points are
small circles, or
dots. Multiple solutions are designed into the Giza
puzzle, a show of sophistication. We shall never learn, which version

to the east side of the Second Pyramid. The fault from Petrie's version
then is 0.00126 cubit, or 0.66 millimeter.
Since the center of this pyramid is already located with
utmost precision, the adjusted Second Pyramid
is identical to Petrie's version.
Petrie's layout of the great pyramids of Giza can be
recreated from scratch on a clean
slate, beginning with the
'13-Step' construction of the regular 5-pointed
star from a line segment, with some involvement of the basic
prime number square root values. The method
has simplicity, total accuracy, elegance, and intellectual
depth. With such attributes, it must be essentially identical to the actual Egyptian procedure of
planning the Giza layout. For instance, working on any other scale would eliminate the phenomenon of whole and round numbers magic. The North to South
between the pyramids must be taken as exactly 1732.05 cubits
It is noteworthy that the method does
not work with the classical tools of geometry, at
least not without a
microscope. Given the scale of Giza, and
differences between drawing objects, the plan had to
be worked out mathematically. In that case,
the knowledge of mathematics guarded by the temples was
clearly on a level unattainable in a neolithic
society less than two millenia removed from the

Yet, we (the readers and I) see

The diagram below shows how the combination of
the old rectangle with the newer one creates a horizontal column, which
is more accurate as such (a combination of two true golden rectangles)
than either of its components.
Pay good attention to what the top rectangle ABCD from the previous diagram does in the context of our
Pyramid Square in the diagram below.
It now extends from CD to OK. This new rectangle, ABOK is vastly superior to ABCD in representing an
exact idea. While ABCD is a downright lousy imitation of a golden rectangle, it is impossible to tell ABOK from a combination of two exact golden rectangles ( ABCD, and CDOK), one vertical, one horizontal. At least on this scale, since the actual exact figure is 10 inches thicker than the original ABOK.
other words, the North-South distance between the two big pyramids
provides a perfect visual experience of a sacred figure of two
golden rectangles, in conjuction with the East-West distance from
the Great Pyramid to the western side of the Pyramid Square. The notion
that this figure was sacred to Egyptians, is supported by my
analysis of a door from Hesire's tomb (Hesire was a colleague of
Imhotep). http://www.vejprty.com/hesirefn.jpg The figure of Hesire engraved upon the door is contained in the same rectangular figure ABOK.
we can also see in the diagram, how really inaccurate the original ABCD
was as a golden rectangle, because the original CD line is 3.8 cubits
to the west of the exact line.
this diagram lets us see, how the
golden diagonal emanating from O is impossible to tell from a line made from the same point to be tangential to the Great Pyramid's

theory - Competitor or Contributor?
Since my own theory draws some important benefits from
work, he has my gratitude and admiration. As for my critique of his work, a brief peer review
of all, our respective approaches differ greatly. While
this reconstruction is done completely
from scratch, Legon starts out by
copying the Great

first, he uses basic geometry, but from there it is mostly a

inspection. It is a show packed with action, exactly
as intended by the original designers!
It has long
accepted Legon's premise that
the north-to-south span of the pyramids
expresses the square root of 3.
Acceptance of this idea is a basic requirement. However,
Legon assumes that
the span was intended to be 1732 cubits
exactly. But, it is crucial
to the reconstruction that this distance be taken as more
accurate by two decimal points
of 1000√3, i.e., 1732.05
Not using this scale would eliminate the
best result for
the location of the Third Pyramid's south-east corner. The next domino
to fall would be the microscopically accurate reconstruction of the
Second Pyramid's vertical axis. Other dominoes would follow. Only the
Pyramid would remain unaffected.
Legon's reconstruction - Legon
give the actual procedure. Rather he states several possibilities,
which are all supposed to lead to more or less the same
result. Consequently, I select those that yield the very best
result on his behalf.
Because there are two possible scales of reconstruction (N-S =
1732 , and 1732.05 cubits), I felt
carry out a reconstruction for each.
Also, Legon says that he measures from the center of
the Great Pyramid's theoretical version, the one with an even
cubits per side (440), but actually works from the center
of the version given by Petrie.
in Legon's plan from Petrie's plan -
(35,713.2 inches) = 1732 cubits
Start by drawing the averaged out square base of the Great Pyramid,
as specified by Petrie. Next, extend the east side to the south to equal 1732 cubits
(Ö3), or 35,713.1 inches. This will be the axial north-south
distance from the north side of the Great Pyramid to the south
side of the Third Pyramid.
Mark 1101 cubits from the north southwards on the extended
side of G1 (the Great Pyramid). This will be the axial distance to the
south side of the Second Pyramid.
Mark 433 cubits ( 250Ö3 = 433.0127..) from
the center of the Great Pyramid westwards. This is the axial distance
to the east side of the Second Pyramid. Since the positions of two
sides, south and east are already known, and because Legon postulates exactly 411 cubits as the intended length per side,
the square base of the Second Pyramid can be now be drawn in full.
Next, if we
make the axial distance between the western sides of
the Second and Third Pyramids 250√2
given to two decimals (353.55 cubits), it is just 0.008 cubit short of
the western side of G3. This is a very accurate
the positions of two sides, south and west are already known, and
because Legon postulates exactly 201.5 cubits, as the intended length per side,
the square base of the Third Pyramid can be now be drawn.
in Legon's plan from Petrie's plan -
(35,713.2 inches) = 1732.05 cubits
This scale goes
to two more
digits in the fractional part of Ö3 than
the one Legon uses. The same procedures used previously on 'his' scale,
achieve nice great accuracy
here as well, but with one important difference - instead of rounded out
values for the square roots, they work with the actual exact
But, it must be noted that
overall, Legon's method gets better results on the less
accurate scale of 1732.
what works really well for Legon, works even better for
this reconstruction. It gets Legon's reconstruction to 5.4
millimeters of the western side of the Second Pyramid, but it gets us
to just 0.51 millimeter. However, Legon's result for the eastern side
of the Second Pyramid is closer by a fifth of a millimeter than
this reconstruction, but that is because Legon does not reconstruct the
Great Pyramid in this position like me, copying it instead.
Legon's division along the east-west axis is accurate to half a
millimeter for the east-side of G2, and half a centimeter for
west-side of G3. For the division along the north-south axis, Legon
uses two procedures, which he deems both accurate.

In my internet search, I came across some 15-step operations,
but then in February of

about 2.5 mm off the desired perfect value for Pi. An
error of less than 3mm was allowed for by Petrie. Hence he could be off

the facts prevail, the conclusion must be that
the average pyramid side was designed with the true value of Pi in mind.

order that the perimeter of the base should express the so-called
'pi-proportion' in relation to the height of 280 cubits, with greater
accuracy than the value for pi of 22/7. In this case, the

a measurement dictates both its exact, and rounded
values. The need
for a side of 440 rounded out cubits arises from
the perspective of Phi. The apothem divided by half the side, or
356/220 equals Phi to the first three decimals (1.618 181818...)
Mike Ivsin's construction produces perfect Phi, with a slope,
which is in Petrie's ± range. It seems that the builders had
achieved this result, too.
Legon abstracts a cohesive system from the Giza position, one dealing
square roots. Although some of these readings are somewhat
Legon suggests logical reasons, why there were
adjustments. In my opinion, Legon correctly identifies an
layer of abstraction in the position. Compared to the
"13 Steps" reconstruction, it is considerably less accurate,
makes perfect sense in a rounded-out way. The more meaning, the more
reason for selection of this plan.
By the way, Legon seems somewhat unhappy over the east-west
distance spanned by G1 and G3, which is 3 cubits too long to express
the square root of 2 as 1414. Did he discount the fact that the
north-south distance between the centers of the same pyramids is three
cubits shorter than the desired distance and thus produces a correct

north to south distance between centers of G1 and G3 = 1411.414161.., the first three digits are correct; the next five are a peculiarity, for 1.414161.. gives the same root to five correct digits when rounded to 1.4142.
These two distances between G1 and G3 also add up to 2828.. the first four digits of the square root of 8,
which equals 2 x the square root of 2. It is interesting,
because in this case the following formula is true:
the square root of "a" cubed equals two-times the square root of "a".
A long-time researcher, Robin Cook adopts the
right approach in observing all strong relations as possible
coincidences first, and then asking, which of the mutually exclusive
relations might be the intended ones. Cook is right, because without
the illuminating background of the 'Pyramid Square', such ideas are a
bit like Plato's shadows dancing on a cave wall. In
such situations it
is easy for a theorist to become convinced that his
recreations mirror the Egyptian planners, before the builders
strayed from the plan somewhat, just as expected, or before the plan
got changed for reasons unknown.
makes sense that the designers had started
out with regular squares. Adjustments were then made
to create a new layer of meaning.
Petrie versus Cole
Excerpts from an old discussion:
What irks me, Jiri, is your persistent refusal to address the question of
intent; you have yet to
provide any separate evidence that this pattern was created intentionally by
the designers of the
Giza pyramids and temples.
Whenever you reconcile the obligatory appreciation for the
beauty of the geometry involved, and the fact that this is Giza, the
issue of intent may become clearer. . Such a design certainly places
the layout into the highest category of sophistication.

(The Complete Pyramids 1997)
the base of Menkaure’s pyramid is 335 x 343 feet.
Yes, this is contrary to Petrie’s measurements
(mean 346.13 x 346.13) but does this mean that
Lehner is wrong?
It most certainly does, considering that his figures differ

in measuring the Great Pyramid.

Cole took series of measurements of the available sections of

Yes, the acclaimed and anomalously accurate casing! The quality of
work, said Petrie, equaled modern opticians, but on the scale of acres.
Determination of lines from the plane of the casing blocks, and their
projection down to the pavement to produce an averaged out line in the
pavement should naturally be superior to relying on measurements from a
single line, as Cole had done.
The descending gallery shows similar accuracy in that it deviates from
its axis over the course of 350 feet by a quarter inch (6 millimeters)
side to side, and only one tenth inch (2.5 millimeters) up and down. In
using the anomalously accurate plane of the casing blocks to obtain a
hypothetical line along the pavement, Petrie seems to have achieved
even greater accuracy.
Corners lying on the diagonals of the sockets:
This was another logical decision by Petrie, which gave his method
further advantage over Cole's. Clearly, the sockets were the target the
builders were aiming the sides at.
Petrie was a consummate professional. In my eyes, his drive

A detail of my analysis also

Petrie's location of the SE corner of G3, within the framework of the
pyramids'containing rectangle: It works with the NS distance set to
1,732, or 1,732.05 cubits.
a) Circumscribe the Great Pyramid.
b) From the SE corner of the containing rectangle draw a big circle touching the circumscribed circle of the Great Pyramid.
c) Go east exactly 1 cubit from the point, where the big circle crosses the SE boundary of the containing rectangle.
The result is a touch over two millimeters to the east of the SE corner of G3, as given by Petrie.
I learned this fact by geometric means,
and since yet another method was a distraction by yielding an even
better result, it took a while to dawn upon me that this fact also helps
your theory. My apologies for the delay in letting you know.
p.s. Since 1,732.05 signals a square root, where is the square?
I think that your theory warrants asking that question. To me, the
square is the extended containing rectangle of the three pyramids. Its area is 2,999,997..
square cubits (or 2,999,824 @ 1.732 cubit). Draw the square, and it
will light up the next clue, bringing the solution a step closer.

Thank you for drawing my attention to your essay on the Giza plan.
I haven't tried to analyse your findings in detail ........ rest omitted
A folllow-up letter on the same day:
sorry, I made a mistake, for a
saving of 0.0005 cubit represents only 0.25 millimeter, and not 1
millimeter. So, the result brings you to 3.15 millimeters east of the
mark set by Petrie. Still, it is better than the discrepancy of 33.9
millimeters, if one follows the procedure in your report.
