Exact Reconstruction of the Layout of the Great Giza Pyramids 

 Introduction

First, let me caution the reader about developing prejudice against this work on account of my 'literary' English. Upon landing in Canada as a young adult, mustering a few sentences in broken English was all I could do. So, bear in mind that if I violate English, it is all in the cause of Science :) 

Since 
1883, when Sir William Flinders Petrie published his geodetic survey of the three great Giza Pyramids, it has been analyzed for geometric, and numeric significance. To show that the three great pyramids are parts of one overall plan, there have been attempts to systematically generate their layout from pure ideas, i.e., clean slate.  Giza abounds with inspiring relationships. But, to safely pin ideas on the original designers, ideas have to prove their mettle by integrating into a system, and being compellingly accurate, of course, if we think that the builders had been capable of such accuracy. There is a number of well known examples showcasing the knack of Giza builders for accuracy, such as that found in the Grand Gallery, or in the total north-to-south distance between the pyramids, hence this sets a standard for measuring and evaluating what we attribute to the Egyptians.
The problem always was that elegant elements of design discovered at Giza, never worked together very well. They always seemed a foot or so out. Nevertheless, on a drawing board 35x35 inches, such ideas may look absolutely accurate, because their faults are diminished thousandfold,  and this has misled many authors into wishful thinking. 
Time to mention John Legon's work.  His reconstruction of the Giza plan works remarkably well along the east-west axis. It is uniquely accurate for three major lines, the east and west sides of the Second Pyramid, and the west side of the Third Pyramid. However, the main north-to-south division produces a much greater fault of 1.25 inches. Why did the Egyptians not achieve comparable accuracy along this axis? It was in their power, so maybe they did. Let that 
serve as a warning sign that Legon's theory may be too simple.
Be it as it may, Legon is correct, when stating that axial spacing between the pyramids approximates square 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 so close to Petrie's plan that had I been familiar with it earlier, I might have accepted it, albeit reluctantly. What a disservice to the ancient builders it would have been, because Legon's interpretation puts them on a level everybody expects, i.e., they had a simple plan, and executed it somewhat unevenly. For this reason, I find it hard to grasp, why Legon's theory does not get more attention and approval from the academy.  
What reception is in store for a theory like mine? In this report I describe in detail an exact, and streamlined construction, whose results comply to Petrie's measurements
with consistent and superb exactitude. At its base lay secrets of the exalted Golden Section. Square roots also play a big role. By being spirited, the construction is of the most appropriate type for sacred grounds. 
I suspect, our skeptically leaning academy will not treat this design kindly because it is, frankly, too good. If pressured, it might embrace Legon's theory, as the simpler explanation.  

               Legon's theory - Competitor or Contributor? 

Since my own theory draws some important benefits from Legon's work, he has my gratitude, and admiration, but it is necessary to subject his work to a critical assessment, a brief peer review of sorts.
First of all,  our respective approaches differ greatly. While this reconstruction is done completely from scratch, Legon starts out by copying the Great Pyramid (G1) directly from Petrie's plan. Then he derives the rest. At first, he uses basic geometry, but from there it is all a march of numbers.  
My reconstruction is essentially visual, it is a progression of pictures, each showing special effects, which embolden further 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 for further success. 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 cubits.
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 Great Pyramid would remain unaffected. 


Reconstructing  Legon's reconstruction -
Legon does not give the actual procedure. Rather he states several possibilities, which are all supposed to lead to more or less the same accurate 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 obliged to carry out a reconstruction for each.
Also, Legon gives the impression that he measures from the center of the Great Pyramid's theoretical version, the one with an even number of cubits per side (440), but actually works from the center of the version, which is as given by Petrie.

Legon's procedure:
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 east 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 2502 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 result. Since 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.
 
Differences in Legon's plan from Petrie's plan    -   When N-S (35,713.1 inches) = 1732.05 cubits

This scale goes to two more digits in the fractional part of Öthan 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 root values!
But, it must be noted that overall, Legon's method gets better results on the less accurate scale of 1732.
Importantly, 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 the west-side of G3. For the division along the north-south axis, Legon uses two procedures, which he deems both accurate. Each procedure works better on one scale and worse on the other, but neither works nearly as well as the procedures along the east-west axis. This unfurls cautionary flags..

The tables given above show that aside from two accurate, and one semi-accurate readings, Legon's reconstruction does not reflect Petrie's data with consistent accuracy. In general, the academy scoffs at the very idea of a unified plan for all three pyramids. With so much smoke around, this 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 could be cleanly translated into a meaningful geometric design, it would mean nothing without the discovery of original blueprints, or a statement from the architect(s). Such extreme prejudice seems to actually dominate the academic establishment, which is quick to label someone a "pyramidiot" just for perceiving some intellectual depth in an ancient design. 
Yet, a true solution towers above others, when it is both accurate, and meaningful. There can be only one such solution, and that's why all other solutions must be imperfect.
If a layout is truly random, there will be no grand unifying idea, and no efficient solution .There is no way to efficiently describe in general terms a random position of three squares on a scale such as that of  Giza, as accurately as this superfine reconstruction of Giza's layout (see the tables above).
How miniscule are its faults? The maximum north-south distance between the pyramids is 35,713.1 inches. To
show
a fault of 1/100"  in a plan of Giza on a computer screen, we need to make it at least a pixel. The total resolution  has to be 3,5  x  3.5 million pixels in order to show the fault. Imagine a 36" square  as a computer screen  containing all those pixels. Its vertical and horizontal lines would sport about 100,000 pixels per inch. The fault of  0.01" would show on this screen as 1/100,000".  Backed by these comparisons, it can safely be said that the solution is microscopically precise. By this token, it is the original method, the scientific soul of Giza.

A tribute is due to Petrie
's brilliant achievement. Although academic opinions tend to profess 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 Cole, by the virtue of choosing the better method under circumstances. I believe in what looks so perfect through the prism of my own reconstruction.  What is revealed is Petrie's modesty! His actual results are an order of magnitude closer than his stated tolerances. It is as if he were given the original plan. Else, it had to be superbly accurate mensuration of superbly accurate objects. That would explain why there is massive precise agreement between my reconstruction and Petrie's plan, and none with Cole's.

                                   Framing - the Pyramids 

The breakthrough to solution of the Giza plan came from extending the enclosing rectangle (blue) of the three pyramids, which is rather ubiquitous in other studies, into a square. This simple step is absolutely vital to understanding the position, but incredibly, no one before me had taken it!
                                         

In this framework, some
prior interesting, but seemingly dead-end observations by others suddenly  become meaningful.  


                      

You can see that the Second Pyramid's vertical axis is surprizingly close to the vertical axis of the Pyramid Square. Next, I divided the square by the golden section (green lines).
Obviously, the square base of the Second Pyramid mimics the small square in the center of the green cross.
For a follow-up experiment, I placed the second pyramid's square base in the center of the cross, and extrapolated its own golden square, and a cross from it. You can see this in in the diagram below. Now, there are two sets of everything (the Great Pyramid is also scaled).
  

                                             


The result is an almost perfect illusion of identity at this magnification.  Could this illusion be a hint that the design of Giza has something to do with the Golden Section?  I thought so. The logical course from here was to see what others had observed on the subject of Golden Section & Giza.  

It is unusual that as far as I know, no one had worked with the Pyramid Square concept before. After all, extrapolating a square from a rectangle is so simple! It was the first thing I had done once I'd had Petrie's ground plan in a CAD drawing (Computer Aided Design). To me this step was elementary, because all my previous case studies in ancient science-art had involved an all important square.

The Giza pyramids dictate their containing rectangle. The rectangle dictates the square. The square constitutes the proper context for analysis. To illustrate what I mean: 

Tedder sees two golden rectangles baseing on the intersections of lines in the capital directions emanating from the center of each pyramid. These facsimiles are very inaccurate


Chris Tedder sees two golden rectangles given by intersections of lines in cardinal directions emanating from the center of each pyramid. He proceeds to propose a possible plan, the Egyptians might have used. Unfortunately, these rectangles have poor accuracy, a fact that reflects negatively on the level of Egyptian skills, and thus the Egyptians were once again the scapegoats for the mistakes of modern scholars.
  

Tedder's site:     http://www.kolumbus.fi/lea.tedder/OKAD/Gizaplan.htm  

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.
In 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. 
Meanwhile, we can also see in the diagram, how really inaccurate the original ABCD was as a golden rectangle, because the original CD line is many cubits to the west of the exact line. 
Moreover, 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  inscribed circle. 
All this is important, because armed with these facts, it is already possible to geometrically reconstruct
with visual perfection the Great Pyramid's square base in relation to the Pyramid Square. The pyramid's side will then be shorter than it is in reality by on this scale invisible seven inches. So, if we suppose that this was how the builders had evolved the Giza plan, their skills suddenly look vastly superior to the level set for them by Tedder.
First stage in the reconstruction of Giza layout




Mirrored Illusions Become Reality


The layout of Giza is very rich
in geometric illusions. It makes decryption tricky. In a spiritual sense, false paths obscuring Giza's recreation (I blundered down a few of those) may well symbolize the soul's perilous journey through the labyrinth of life to fulfilment. 
At the risk of sounding mysterious,  reality then is the axis of symmetry between illusions.. 

Length of the Royal Cubit

This reconstruction more or less accepts units of measure theorized by John Legon. He makes a strong case that the North-South distance between the pyramids (one side of our Pyramid Square) was meant by the builders to equal in cubits 1,000 times the square root of 3, or 1.732.
Accordingly, I have tested the Pyramid Square side set to 1,732 cubits, as well as the 1,732.0508.. from exact construction. Thirdly, I have tested it as 
1,732.05 cubits, which would be extremely accurate planning by the Egyptians, as it extends to five decimals of the square root of 3.
The latter scale is the one that makes the reconstruction work. Some
 sensational value readings pop up, looking definitely non-random as a group. Exact numbers rather than geometric procedures are used in three instances in the reconstruction. The wind was out of its sails until I gave up using exclusively dimensionless geometry, and applied the cubit scale. By this virtue, 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 resort to these exact numbers.
Petrie's measurements at Giza, and inside the Great Pyramid had produced slightly differing values for the cubit. In the end, he settled for an average of 20.62" (inch) per cubit.  This reconstruction's cubit is 20.61897", which is almost without any doubts correct. Amazingly, Petrie is only 1/1000" off this value.

  South to North between the pyramids = 35,713.1 inches = 1,732.05 cubits  =  a side of the Pyramid Square
                               
                           
1 cubit = 20.61897.. inches 523.7218 millimeters

It makes good sense for the designer to stop at the exact value of 1732.05 cubits (here is an example of a puzzle using decimals from La Marche, Stone-Age France ). The digit 5 for hundredths is followed by a zero, which means no thousandths (milli-cubits?) to deal with (1/1000 cubit is just over half-a-millimeter). The next digit is already too fine, so, this is a natural cut-off point. As a representation of the square root of 3,  this value differs from the true by eight ten-millionths of a unit -  1.73205080..

         
  Measuring Success  -   Precise Values

The first criterium is how close the reconstruction gets to Petrie's position. The reader saw that the faithfulness of the reconstruction to Petrie's plan is in a class of its own, and nothing else comes close. Another aspect of the reconstruction, which puts it into a class of its own is the undeniable extreme proximity of many of the resulting measurements to whole or half cubits.

          How to Recreate Petrie's Giza Ground Plan From Scratch
                                                 part one 
                        The Foundation - Classic Geometry

The Giza plan evolves from a solid theoretical foundation - the Golden 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. I had learned it from the Nazca-monkey. That is not to say no one did this construction in modern era (post Egyptian), but it is a bit surprizing that efficiency of construction is not a greater concern nowadays. 
                                               
                                                   
starting construction for the Great PyramidDiagram 1

Start with the above classic procedure. It begins with a horizontal line, and takes ten steps. Two of the steps involve help circles (to draw the axial cross), and these are not shown for clarity reasons. The eighth step draws the key Golden-circle ('c' in the diag.), which is centered in the bottom tip of the axial cross. On steps nine and ten, lines are drawn from the top of the axial cross, as tangents to this circle (at P1, and P2). These lines create an angle of 36 degrees exactly (like on a 5-pointed star).  

Before going on, this simple diagram already has two crucial elements:
* The base length of the golden triangle, given by the 36° angle intersecting the horizontal axis, is the same as one side of the initial Great Pyramid in this reconstruction..  

* The circle from step 2 of the construction, is the instrument, which eventually adjusts the initial Great Pyramid to 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 reconstruction.

Diagram below:

T
hree more steps complete the star: On step eleven, a circle from the point Q (the Q-circle) is drawn through the top and bottom of the axial cross. This creates two points (1,2), which are then connected by lines to the bottom point of the axial cross (3). That's it!  
(In trade terms, the simplicity of the construction is 13).

The unique element of this construction is the Q-circle, or its mirror image on the other side of the vertical axis. After the Q-circle, there is a choice of things to do with the position.  


                   point Q gives four points of the star - two tips - two corners of the inside pentagonDiagram 2


The position below is based on diag.1, but is rotated 90 degrees counterclockwise. It is generic, and beautiful in the simplicity with which it creates a slew of golden rectangles..

 Diagram 3

*    A line from 'A' through '1' to 'D' has the angle of a diagonal in a vertical golden rectangle, hence 'ABCD' is a golden rectangle.
*    A line from 'B' through '1' has the angle of a diagonal in horizontal golden rectangle.
*    A line from 'D' perpendicular to 'AD' is a diagonal of the golden rectangle - 'CDEF'.  
The combined form of the two golden rectangles 
ABCD + CDEF is  called the 'Horizontal Column', which is very important in this reconstruction. The Horizontal Column is next transformed into a square, simply by adding the golden circle's diameter to its height (suspend the circle from the underside of the column). A 45° line drawn from 'H' will be one of the diagonals of the Great Pyramid.  'E' - will be the center of the initial Great Pyyramid. 

The two golden circles in the diagram intersect each other at points, which lay on a golden diagonal parallel to AD.

The ratio of the Horizontal Column's height to the height of the rest of the square is 2(Φ-1).  

The points A-B-I-J-H mark four segments in a row, where each segment forms the Φ-ratio with the neighboring segment(s)

         Corners of the Initial Great Pyramid

In the diagram below, on both the blue 13-Step star, and its derivative - the red star, distances such as 'AB', and 'EF',  are equal to 'CD', which is a side of the initial Great Pyramid. At this scale, it is impossible to see any difference between the initial, and the true-size Great Pyramid.
This diagram shows one way of producing the initial Great Pyramid. A line through 'P', whose angle is that of a diagonal in a horizontal golden rectangle, then intersects at 'C' with one of the diagonals of the initial Great Pyramid (the diagonal lines must originate from the NE corner of the Horizontal Column).
The green square's line with a line of the red star is 'X',  a big point, see diagram 6.  

       
Diagram 4

Lines a, b, c, and d,  all have the golden diagonal angle.  
In the diagram below, three of the four - 'a', 'b', and 'd' project the Great Pyramid onto the "13-step" construction.

Line 'b' is tangential to the inscribed circle of the pyramid, and that also permits the reconstruction. This is the only generic way I know of to construct the initial Great Pyramid. Every other way has to do with the 13-Step star..

Line 'a': As a radius, it will usher this reconstruction from theoretical analysis to the applied stage. Let's call it the  'transmission-circle', when it is its turn.
Line 'b'  measures 1642.00222202 cubits, a typical measurement in cubits for this reconstruction.
Diagram 5


In the diagram below: One Q-circle intersects sides of the diamond (square), the other one intersects extended lines of those sides. Lines 'e'and 'f' originate from these intersections, and then intersect the initial pyramid's diagonals at its corners  Either 'e', or 'f' suffices for the pyramid's construction.
Altogether
, there are five procedures, each projecting the same initial pyramid. Only one is 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 possibilities therein.  If the designers had known only the single generic way to project the initial pyramid, the incentive for selecting it at all would be strongly diminished. 

                     Diagram 6

If the north-east corner of the initial Great Pyramid (G1) is exact in this blueprint, the other corners are over 6 inches short of Petrie's locations. Yet, that distance shrinks to nothing on any drawing board ( 1/100 millimeter, if the board is 35" tall). Having the initial pyramid sets the stage for its adjustment to the exact specifications given by Petrie.
      
         The North-South division - Locating the south side of G2


The point marked 'X' in the above, or below diagrams sets a point on the south side of the initial Second Pyramid (G2).  If the height of the big square is Giza's 907,112.74 millimeters, then 'X' is 4.2 millimeters above the south side of G2, as given by Petrie.

A fact to note here is that without the '13-Step' star there can be no point 'X'. Not having 'X', would in turn eliminate the best result in the location of the Third Pyramid's
SW corner (to 0.51 mm).

On the same scale, the length of a side of the initial Great Pyramid, or of the pentagon within the 13-Step star, is remarkably precise 439.50009259 cubits. It's a strong signal that the units used are correct. 

The distance between adjacent tips of the 13-Step star, or one side of the smaller star = 1150.626180 cubits. Here, we see five consecutive digits of Φ squared (2.6180).  Coincidence?  

     Diag.7The 5-pointed star associated to the Great Pyramid                        

     

                               The Pyramid Square

After the initial pyramid (proto-pyramid), the big square in diag.3 is extended to the pyramid's north-east corner to function as a containing square for the pyramids - the Pyramid Square (35,713.1" or 1,732.05 cubits per side).  

                        How unique is the 13-Step star?

Spoken poetically, the 13-Step star is the guiding star of Giza's ground plan, much more so than stars of the Orion constellation.
Repeated Internet searches for instructions on how to construct a pentagram, yield none as fast. I came across some 15-step operations, but then in February of 2010, I got a letter from Mike Ivsin about his original construction of the regular pentagon. Applying Ivsin's ingenious original idea to pentagram construction, I found that it is a 14-step process.  In the below diagram, the first five steps are in black color, the following five are blue, and the rest are red. Two of the circles appear as Vesica Pisces in order to clean-up the image.


a 14 step construction of the regular pentagram, 5-pointed star


Magic happens, when Ivsin goes on to add just one circle ('c') to the basic construction, whose radius equals the length 'a' of the star's arm (diagram below).  Now, extend line 'b' so it meets 'c', and draw the line 'd'. What we have here is the cross-section of the Great Pyramid!

                construction of the Great Pyramid from the 14-step construction of the regular 5-pointed star, pentagram


The angle between lines 'e' and 'd' is
51.82729237 degrees, which rounds out to 51º50'

A quote from Petrie: On the whole, we probably cannot do better than take 51º 52' ± 2' as the nearest approximation to the mean angle of the Pyramid.. 

*   Hence,
51º50' complies to the lower ± limit set by Petrie.
*   The ratio of 'd' to 'e/2' is the exact value of 
φ (Phi).  This is better than the usual Phi formula for the Great Pyramid: 356 / 220 = 1.6181818   

It is true that the Giza layout, as well as the Great Pyramid's cross-section seem derived from Golden Section designs, namely, the construction of the regular pentagram needing the least number of steps, 13, and possibly, the only other such construction needing less than 15 steps. In any case, the nature of each construction is consistent with the other, and thus augments its credibility.
Giza  broadens the Nazca - La Marche connection (between
the Nazca-monkey, and one Stone-Age engraving from the rock shelter of La Marche, near Lussac-les-Châteaux, France, with 1,500 masterfully engraved stone tablets, now kept in museum vaults, and largely unknown to the public
). Why do these three ancient works from different ages and continents encode the same construction?  Is there some connection to the apparent imagery of the so called Abydos Helicopter, which also encodes a rigorous construction of the Golden Ratio?   
 


       How to Recreate Petrie's Giza Ground Plan From Scratch
                                            part two
                     Building Upon the Geometric Founfation               
                 
                                       Two Look-alike Circle Pairs

Much like the ubiquitous instruction guides for "dummies", the Giza designers provide easy to follow guidance in the form of pictorial clues. All one has to do is just get on the right track.  After the initial Great Pyramid, 
the following catches the eye: The widely used Giza containing rectangle, and the Pyramid Square share the same south-eastern corner. I wonder, how many people had drawn an experimental circle from there to touch either the Great Pyramid's circumcircle, or the south-eastern corner of G3 to observe that it then seems to touch the other object, as well. Moreover the circle appears to be the same size as the transmission circle.

                     
diag.8

But, because no one else views things in context of the Pyramid Square,  no one had seen how the Great Pyramid's circumcircle seems to touch G3 from the other side, when copied to the SW corner of the Pyramid Square (diag. above). This is certainly a startling effect, albeit up close it is not all that accurate.
In the diagram however, the pyramid's circumcircle has been expanded slightly to be tangential to the transmission circle. So, we have two pairs of alike circles
, which look the same from high up above Giza.

Another special effect is shown below. Line-g drawn between the intersection (
on the left) of the two transmission circles , and the SE corner of the initial Great Pyramid then duplicates the angle of the other golden diagonals to  0.0015º.   This is a very fine value. And conversely, the true golden diagonal drawn from the same corner then comes to within 0.66'' of the same intersection.


                     


  


                        Very Special Effects

This latter transmission circle-pair wheels the entire reconstruction fast forward, as there are more special effects. One  involves the big circles from each pair (described above).  
                                                              

diagram 9

The diagram above is a close-up from diagram 7 of the situation in the south-east corner of  G3, the Menkaure pyramid. Lines 1 and 2 are sides of the pyramid,  'a' and 'b' are the two big concentric circles (the transmission circle, and its look-alike tangential circle to the Great Pyramid's circumcircle).

With spectacular exactitude, the circles are equidistant to the pyramid's corner
!

The centerpoint of the distance between the circle lines is 3.4 millimeters to the east of Petrie's pyramid corner. The radius of the small cyan circle inscribed between the big circles is 1.0005 cubits, a highly precise value for one unit.
Since we are going to precisely reconstruct the Great Pyramid's position, we shall also be able to repeat this trick, and pinpoint the southeast corner of Menkaure's pyramid with equivalent accuracy. The radius of the aforementioned circle then works out to 1.00050550 cubits.
                                                

The same trick using the circle 'c' (below), which is tangential to the circumcircle of the initial Great Pyramid, serves to produce the SE corner of the interim G3 - version # 2.  It is 3.68 inches to the west of the original, and half-way between a and c. 
                 
                 simple method of establishing the south-east corner of the Menkaure pyramid

                                  The Channeling Method


Given two possible versions of the original, which create a channel of parallel, or concentric lines, often, the solution is simplicity itself - one step only:

                        "Go down the Middle of the Channel!" 

This is the method that duplicates the 
Great Pyramid in Petrie's plan by producing the exact location of its NW corner (the NE corner is known by default). It doesn't end there, though. In one fell-swoop, the same procedure (substituting Horizontal Column for the Rising Column) yields a fairly accurate location for Menkaure's SE corner - half-an-inch (0.506"), west of its location in Petrie's plan. A method has to be elegant, and this is elegance!

To digress a little, t
he symbolic language of coincidences around the transmission circle lets us follow the trail, but as long as I started the reconstruction from a golden rectangle without the precursory steps, I was left wonderingWhy use the transmission circle? What's its importance? Then I saw it in the context of the '13-Step' construction, as in the diagram below. 

A 135 degree line from the NE corner of the Horizontal Column (the pyramid's diagonal) meets the line through points 1, 2, 3, 4 at
 the NW corner of G1.
 The purple circle whose radius extends between 3 and 4, is an exact twin of the golden circle. This line was used in the construction of the initial G1, and now it serves as the radius of 'transmission-circle'.  Since the 'transmission circle' dominates this stage of the construction, it matters a lot that it is originated by such classy fundamental geometry.  


 
diagram 11
 


         Menkaure's initial vertical axis   ('go down the middle')

N
ext, some elements of the position are manipulated in several simple operations. The midpoint of the gap between the circles sandwiching G3 in diagram 8,  is 4.2 inches to the west of Petrie's vertical axis for the pyramid. Draw a vertical axis from there for our initial G3.

 
         The Initial Third Pyramid (#1)

a)
* Center a circle at the point, where this vertical axis crosses the Horizontal Column.
* Have it touch the far side of the 
little circle in the column's SW corner.
The little circle is already a part of the position, since its 
diameter is a side of the inner pentagon of the '13-Step star',  and it is also the inscribed circle of the initial G1.
b)
The section of the vertical axis below the new circle is taken as equal to one side of G3. O
n the basis of this assumption, the pyramid is completed around the axis.

                 
intermediate stage of duplicating Menkaure's pyramiddiag.12


The NW-corner of the interim G1, and the SE corner of G3 in the above #1 version, are crucial ingredients for a simple operation, which makes the reconstruction of the Great Pyramid identical to Petrie's plan. 

Operation Rising Column 

Robin Cook says that if we enclose the pyramids between two 45º lines (perpendicular to their N.W. by S.E. diagonals), as in the diagram below, the long axis of the resulting column (the Rising Column) is almost exactly the same as one of the second pyramid's diagonals. 

                          the Horizontal Column & the Rising Column diag. 13

But in Petrie's plan, the axis actually runs 13.82 inches east of the pyramid's diagonal. However, this relationship does look accurate on computer screens, or paper.
Meanwhile,
I noted another special effect in this position, one three times more accuratethe width W-Z of the Rising Column is just 4.32 inches more than the width A-B of the Horizontal Column. Comparing, or substituting the reconstructed columns for each other could therefore be of interest, and is next on the agenda. 

The idea that the bottom side of the reconstructed Horizontal Column should also be the horizontal axis of Khafre's pyramid (G2),  is a 10.12 inches miss. Marking the actual (Petrie's) thickness of the Rising Column  straight down from the top side of the reconstructed Horizontal Column gets to 0.94 inch south of the second pyramid's horizontal axis.

  Exact Repositioning of the Great Pyramid

Substitute the width of the Horizontal Column for the width of the Rising Column (axis over axis). Then the situation in the Great Pyramid's NW corner looks like the following diagram.


        pinpointing the NW corner of the Great Pyramid  diagram 14
            
                                           'go down the middle'

The long axis of the channel between the western sides of the two rising columns is identical to the western side of the rising column in Petrie's version. Or, a line drawn vertically down from the northwest corner of the wider Rising Column becomes one with the western side of the Great Pyramid in Petrie's version.
 

O
n the line through the north side of the pyramid, both the west side of the wider Rising Column, and the NW corner of the proto-pyramid G1, are equidistant to this corner in Petrie's version. The difference in length between the reconstructed and the original versions of one side of G1 is too tiny to be noticed, at 0.0101.. inch (1/97), or 0.26 millimeter, or 0.0005 cubit. The pyramid centers are 0.007 inch, or 0.19 millimeter apart. In other words, the two versions of the Great Pyramid are identical.

The 
reconstructed value:   439.827 (439.8273..) cubits, or 9,068.8 inches ( 9,068.79) per side.

439.82732 /  Pi  =  140.001..   The pyramid needs to be about 1 millimeter higher than its theoretical height of 280 cubits, to be perfect with respect to Pi, and this reconstruction.. 


Petrie's value:                     439.828 (439.8278..) cubits or,  9,068.8 inches
  
Petrie's plan is under .005 cubit (about 2.5 mm) longer than the optimal value of 439.823 for Pi encoding, while this reconstruction is closer by a hair: 

Pi times half the pyramid's height  =  439.82297150..  or, 439.823 rounded

Operation Rising Column also yields a similar benefit in the diametrically opposite corner, at that stage, the best reconstructed length for a side of G3 : This is already # 3 version of initial G3. (the SW corner is a constant in all three versions).


diagram 14b

In the diagram, a and b are sides of the #1 initial version of G3, and 'c' is the reconstruction of the eastern side of G3.  It is an obvious improvement.

Note: Neither 
the Great Pyramid nor Menkaure's pyramid requires Khafre's pyramid for reconstruction. 


  An Accurate Reconstruction of the SE corner of G3

With the Great Pyramid duplicated, it is now possible to repeat the steps from diagram 8, using the duplicate.

             
diagram 8


Above is a close-up from diagram 8 of the situation in the south-east corner of  G3, the Menkaure pyramid. Lines 1 and 2 belong to the pyramid.  Lines a and b are the transmission circle, and the tangential circle to the Great Pyramid's circumcircleGoing down the middle again, the centerpoint of the distance between them is 0.13 inch, or 3.1 millimeters to the east of the pyramid corner as given by Petrie.

Of interest is the distance between lines 'a' and 'b'. It is expressed by the cyan circle, whose radius is 1.0005.., a rather exact cubit.

                   Records are made to be broken


There is also an ingenious, and numerically meaningful way to pinpoint Petrie's south-east corner of G3 (Menkaure) with striking accuracy.  The reconstructed SW corner of G3, and using the cubit, as given in this study, is all we need. Thus this reconstruction becomes possible before the reconstruction just described above, but it is by no means obvious. One could easily be distracted by the other accurate solution for the same corner,  and come to think about it, a perfect false door.


                 exact solution to the size of the third (Menkaure) pyramid
diag. 15


The location of the SW corner of G3, the third pyramid, yields some notable readings in cubits.

a)
However, first, we note that the distance from the SE corner of G3, as given by Petrie, to the reconstructed SW corner of the Pyramid Square is:

  516.00
5,  516 cubits almost exactly. 


b)
The distance between the reconstructed south-west, and the Petrie given south-east corners
of the third pyramid becomes what many authors posit to be its intended length:  

201.
5 0246 or 201.5 cubits (the small change 0.0026 is worth over one millimeter)

c)
THe distance between the SW corner of reconstructed G3, and the SW corner of the Pyramid Square:  


314.
5 0275

The fractional parts in the above 201.50246  and 314.50275 are very similar:

        314.50275 from the reconstructed SW corner of G3 to the SW corner of the Pyramid Square
      -201.50246  from the reconstructed
SW corner of G3 to the SE corner of Petrie's G3    
    = 113.00029
       

 

Put into words, if we 
flip over westwards the distance between the reconstructed SW corner of G3 and Petrie's SE corner, it is short of the SW corner of the Pyramid Square by:

113.0003
cubits

 1/6 millimeter short of being perfect 113 cubits.

This remarkable arrangement seems to be suggesting an easy way of reconstructing the SE corner of the Menkaure pyramid to 0.0003 cubit, and an absolute zero on the Giza scale.

Reconstruction of the Third Pyramid's SE corner   

Mark exactly 113 cubits from the SW corner of the Pyramid Square towards the SW corner of G3. The remaining gap to the corner becomes the radius of a circle centered in this SW corner of G3. This circle then locates the SE corner, as given by Petrie, to within the above mentioned  (1/6) millimeter, or  0.0003 cubit. In plain English, the two locations are perfectly identical. The accuracy is superlative, and never seen before in any analysis of Giza.        
 π

In terms of whole numbers. there is a 113, and a 314 here, two thirds of a certain Pi approximation.  

  Why 113?

113  x  
π  =  354.9999..

355   /   π  =  113.
0000096

The circumference of a circle with the diameter of 113 is 
a perfect 355 for all the practical purposes. 
355/113 must approximate π close to perfection:
 
355/113 = 3.141592..  -  The best approximation of Pi given as a ratio of two whole numbers.  

Accident? If so, it joins a plethora of coincidences pertaining to Pi, for which Giza, and especially the Great Pyramid are famous. Without it, there would be no exact reconstruction of  the SE corner of G3, however. We need that one for the exact reconstruction of the Rising Column. The latter then takes part in the finding of G2's center.

The Layout of Khafre's Pyramid (G2)

Lumber in the Yard

Earlier the reader saw a way to position the south side to within four millimeters of the original Second Pyramid. Given the center, the reconstruction would come out very nicely. Some usable data is mentioned in the note under diag. 19: 'marking the actual thickness of the Rising Column (W-Z), downwards from the top side of the Horizontal Column, gets to within 0.94 inch south of the Second Pyramid's horizontal axis'. 
We can duplicate the Rising Column, and in so doing, get to within 0.94 inch of G's horizontal axis. Yet, although this is a nice approximation for the horizontal axis, its true function is to take part in locating the vertical axis

Channeling the Solution of  the NW by SE Diagonal of Khafre's Pyramid (G2)  

G2 - diagonal simulation # 1

 Alison's circle

Jim Alison had read the position 
in the diagram below, as saying that a circle (Alison's circle) centered in G3, whose radius is the horizontal distance between the centers of G1, and G3, then closely approximates the Golden Cut in the given line (marked Phi)This line runs from the center of the #2 interim version of G3 to the point of intersection between the inscribed circle of the initial Great Pyramid, and its diagonal. Plainly visible in the diagram below, Alison's circle finds the intersection 'I' between the golden diagonal 'c', and the second pyramid's extended diagonal. So, let the golden diagonal 'c', and the Alison's circle set a simulation of the diagonal of G2. This relationship is an order of magnitude more accurate than the one Alison noted. The simulation is 0.66 (0.6592..) inches northeast off the original.

      'b' the bottom line of the Horizontal Column 
meet
0.66 (0.664..) inch southwest of the diagonal 'd' of the pyramid in Petrie's plan. This creates a point of insertion for the diagonal simulation 'c'. 


                               

  diag. 17


The channel axis between the diagonal simulations #1 (line 'e' in the diag), and #2 , runs 0.0001 cubit, 0.003 inch, or  0.07 mm southwest of the diagonal as given by Petrie.. The channel axis is identical to Petrie's diagonal.
------------------------------------------------------------------------------------

There is also another way of replicating the same diagonal, which comes to within 0.006 inch of Petrie's version. It is really simple .


The big red circle is actually double, with centers in both the #2 and #3 interim versions of G3: From the pyramid-center of each version, draw a circle through the SW corner of the (golden) Horizontal Column. Each seems tangential to one axis of G2. In fact, both come close. 
G3 #2 version - the circle is 0.8286 inch short of the axis, while in
G3 #3 version - the circle is 0.8163 inch past the axis.
The axis line of this channel is 0.006 inch, 0.0003 cubit, or 0.16 millimeter to the southwest of the original G2 axis given by Petrie. 


The Vertical Axis of the Second Pyramid & the Center

Earlier, the Horizontal Column, when substituted for the Rising Column, let us duplicate the Great Pyramid, as it is in Petrie's plan. But, since this is the ambitious Giza plan, the same trick works in reverse, and with even more spectacular results! The Rising Column in its final form, when suspended from the the top line of the Horizontal Column, falls 0.94 inch south of the second pyramid's horizontal axis (cyan in the diagram below).  This line simulates the axis nicely, but its true purpose is different. 

It meets the Diagonal Simulation #2  0.0014 inch, 0.035 millimeter, or 0.00007 cubit east of Petrie's vertical axis.
Two simulation lines in tandem are wildly successful in getting a point on Petrie's vertical axis. An unaided human eye cannot see 1/1000 inch. Considering our workspace is Giza,  any hopes at the outset for this kind of results would be ridiculous. 

             

 
diag.18  

The vertical axis and the channeled diagonal together locate G2's center a pinpoint away from Petrie's plan, at 
0.005 inch (1/200"), 0.13 millimeter, or 0.00025 cubit. We know the position of the southern side to 4 millimeters since early on, therefore G2, the Second Pyramid can be recreated with impressive accuracy even before the final adjustment.  


          Final adjustments - the Third Pyramid

Having the initial Second Pyramid permits testing Legon's ideas in our settings. 

1:
The east-west (axial) distance between the west sides of the Second and Third Pyramids equals  250√2 
cubits.
This postulate works nicely for this reconstruction, locating the west side of the Third Pyramid 0.006 cubit (3.45 millimeters) west of Petrie's version.  (It doesn't work too well for Legon's reconstruction.)

2:
T
he east-west distance between the center of the Second Pyramid and the west side of the Third Pyramid equals  250√2 + 205.5.
This postulate works even better, locating the west side of the Third Pyramid 0.003 cubit (1.5 millimeters) west of Petrie's version


3:
Legon also implies that counting westwards from the east side of the Second Pyramid, 
250√2 + 411 cubits locates the west side of the Third Pyramid.
This formula works the best, as it locates the west side, or the  SW corner, 0.0007
cubit (0.38 millimeter) east of Petrie's plan. The other corner of the south side is given with even greater precision, hence the Third Pyramid can be recreated exactly as given by Petrie.  
This formula also works nicely for Legon's reconstruction - as it gets to 0.01 cubit (5.4 millimeters) east of Petrie's version.  


                       
Diagram 19



4: Working with the Pyramid Square confers an opportunity to note another Legon-style formula for the reconstruction. Draw line d eastwards from  the SW corner of the Pyramid-Square to the length of 250√2-39 cubits. It ends 3.32 millimeters west of the Petrie's version of the SW corner of G3.  
Moreover, segments b and d have a horizontal 
overlap of 0.00026 cubit,  0.005 inch, or 0.13 millimeter!
How much more proof does one need to recognize that Legon really did discover something? Of course, this is yet another example of the validity of the Pyramid Square's concept, which Legon never worked with.
So, far we counted four accurate ways to employ an exact formula containing
250√2 towards location of the SW corner of the Third Pyramid.  As to the SE corner, earlier it was located by the means of 113, hence another exact number. Again, there is consistency of design!

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, they are in reality small circles, or dots. Multiple solutions are designed into the Giza puzzle, a show of sophistication. We shall never learn, which version was the one implemented on the ground. 

Final adjustments - the Second Pyramid

Draw a line westwards from the vertical axis of the reconstructed Great Pyramid, whose length is 
2503 , or 433.0127.. cubits). Make this the distance 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.

Conclusion:

Petrie's layout of the great pyramids of Giza can be accurately recreated from scratch (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. This method
has simplicity, accuracy, beauty, and intellectual depth. Therefore, it must be essentially identical to the actual Egyptian procedure of planning the Giza layout. The scale is what makes the solution work its magic. The North to South distance between the pyramids must be taken as exactly 1732.05 cubits (1000√3 given to six digits).
Since the method does not work with the classical tools of geometry, at least not without a microscope, given the scale of Giza, and the hairline  differences between drawing objects, the plan had to be worked out mathematically. Thus, 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 hunter-gatherer stage.
Asked beforehand, if a microscopically exacting solution to the Giza ground plan were possible, I would have naysayed it, because even if there were an overall plan based on exact ideas, and it were executed flawlessly, it would not be possible to measure the perfect result accurately enough. This would have given rise to discrepancies. Yet, we (
the readers and I) see such a solution here. Forces of chaos and chance are not kind to liberal occurence of exacting geometry and numbers. That's why speculation about advanced prehistoric science that had somehow  survived to an unknown degree until dynastic Egypt under secret guardianship of the temples, simply cannot be avoided.

Notes

                   Drawing Inspiration From Ideas of Others


                Intial Observations - The Pyramid Square & Khafre's Pyramid

This was my first experiment: the Pyramid Square gets a basic Golden Section grid (diag. below).  Lines of the grid create a Golden-cross within the square.
Next, another Golden-cross is extrapolated from t
he square of the G2 (Khafre's pyramid). The two Golden-crosses are then superimposed over each other for comparison. The similarity in size is striking.

In the diagram below, golden proportions added to the G2 in its real location seem to find some correlation to the south side of G1. Here as well, we encounter facsimiles of golden rectangles.

These results were encouraging. Not wanting to rediscover the wheel, before doing anything else, a search was in order on the subject of Giza layout. There is an informative article over at Jim Alison's site:  http://home.hiwaay.net/~jalison/gpsp.html  
It deals with work by John A.R. Legon, Chris Tedder, Robin Cook, and Jim Alison himself on various notions of a ground plan of Giza's major pyramids.  Note how none of the sites refer to this study, however. Is it so worthless? Let's hope, its not a case of  "Hey, Johnny-come-lately,  don't you eat eating my porridge''.

http://www.kolumbus.fi/lea.tedder/OKAD/Gizaplan.htm  -  Tedder's site

Jim Alison's rendition of certain ideas by Chris Tedder was holy water on my mill:

* Perpendicular distances between the pyramid centers produce two golden rectangle facsimiles (ABCD, and DEFP).

           Alison's magic circle
diag.c


* Alison's circle  -  The segment F-H is very close (0.8º) to holding the 45º angle from the horizontal. A circle, whose radius is the east-west distance between centers of Khufu and Menkaure pyramids, is drawn from the center of Menkaure's pyramid. It then divides F-H at G by the (quasi) golden proportion:       
                                   
22,616 inches  / 13,954.114 inches  =  1.621

The Breakthrough

Following the above directions, I added the design to my Giza plan, in the context of the Pyramid-square. The result was spectacular!

Both golden rectangles create two new golden rectangles with the Pyramid Square:

Tedder's Secondary Rectangle  #1 An extension of Tedder's horizontal golden rectangle A-B-C-D to the west side of the Pyramid Square is itself a facsimile of a golden rectangle, the vertical rectangle C-D-O-K
                                                   
C-D divided by C-K =  1.627   

Tedder's Secondary Rectangle #2 - Alison's circle intersects the extended diagonal of the second pyramid rising north due west at the I-point. The distances I-J and I - L form the golden ratio. 

 I-J  /  I-L  =  1.6199      less than 2/1000 off the true Φ value  


The horizontal rectangle I-J-K-L is therefore an excellent facsimile of a golden rectangle.

There is a steep rise in the accuracy of the new and more complex position over the old one. 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.
The diagram compares the Horizontal Column based on Tedder's rectangle, and my reconstruction of the Horizontal Column out of two true golden rectangles (from the center of the Great Pyramid to the west side of the Pyramid Square). Note that visually, the two Horizontal Columns are as as one. Their component rectangles are not.  Tedder's rectangle (black) is obviously inaccurate, as the vertical line from the third pyramid's center is visibly not the line that cuts the Horizontal Column into two golden rectangles. To showcase these facts, the diagram is page-wide.


First stage in the reconstruction of Giza layout

Starting from the Horizontal Column

This was my original method of reconstruction of the initial Great Pyramid:

Draw two golden rectangles, a vertical one on the left, and a horizontal one on the right, diagonals radiating from their corners,. The rectangles form a single column - the Horizontal Column.

                                 a geometric idea of the GreatPyramid within the Pyramid Square


C divides A-K so that if C-K equals Φ - 1, then A-C equals Φ,  and A-B equals 1.
The length of the combined rectangle (the Horizontal Column) then is 2Φ - 1.)  

1) The center of the Great Pyramid is at the top right corner of the Horizontal Column.
2) The left side of the Horizontal Column is the western side of the Pyramid Square.
3) The diagonal 'a' is tangential to the inscribed circle of the Great Pyramid (diag.6). This circle is then enclosed in a square, i.e., the pyramid sides.
4) The lines through the north and east pyramid-sides are corresponding sides of the Pyramid Square. With three sides of the square known, so is the fourth - the bottom of Square. The south side of the third pyramid lies on the square's bottom 
(diag.7).

Naturally, the golden rectangles above could be preceded by a number of different starting positions. But, only the '13-Step' stars produce a close location for one side of G2.

Whenever you reconcile the obligatory appreciation for the eternal 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.

It most certainly does, considering that his figures differ wildly from not only Petrie, but also Cole, who after all did come close to Petrie in measuring the Great Pyramid. It pits him alone against two widely acknowledged professionals. plus, Lehner was caught cheating in a drama of his "This Old Man Pyramid", if I have the title right. A mechanical shovel was used to move some blocks, but no mention of the fact was made in the flick.

I found that typical of the PyramiPhobia, which so torments some academicians they will sell their soul to the devil.

> > from Cole's survey report:

>> "These differences in azimuth are due to the fact  that the new azimuths are found from the actual directions of the sides determined from the excavated pavement,

Cole took series of measurements of the available sections of the excavated pavement. The various hypothetical lines were then averaged out, and extended until they met near the corners. Considering how close Cole comes to Petrie, he did a great job!

corners lying on the diagonals of the sockets.”

a) 
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.

b)
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 to provide the most accurate data on Giza surpassed Cole's. After all, Cole could only be bothered to survey one pyramid. Thus he forfeited further experience with measuring at Giza, which might have given him a little more insight.
The fact that Petrie's measurements set the position up for an incredibly accurate regeneration from a clean slate using the noble Section, can by no means be discounted. With this reconstruction of the Giza-layout everything clicks into place. A click in the reconstruction - a booming cannon shot across the bow of Egyptology!



Integration of ideas by Legon, Alison, Cook and Tedder into the Pyramid Square published on April 15, 2008
Reconstruction of the Giza Plan added on April 29, 2008.                                                               



Petrie's value of 9,068.8 inches, or 230.348 meters, or 439.82782340 cubits of the actual average side by the standard of this study, is 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 by that much, and the pyramid may have been built perfect. If we let the facts prevail, the conclusion must be that the average pyramid side was designed with the true value of Pi in mind.

John Legon writes:

"In terms of the Giza royal cubit of 0.52375 metres, the actual mean side of 230.364 metres corresponds to 439.8 cubits, with an average variation in the sides of only 6 cm or 0.1 cubit. Petrie suggested that an adjustment may have been effected in 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 theoretically exact mean side-length would be 439.822... cubits. It seems that the builders achieved this result while retaining the round number of 440 cubits in the south side."


Naturally, a measurement dictates both its exact, and rounded out 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 with square roots.  Although some of these readings are somewhat approximate, Legon  suggests logical reasons, why there were adjustments. Legon is right. He correctly identifies an additional layer of abstraction in the position. Compared to the "13 Steps" reconstruction, it is considerably less accurate, yet it makes perfect sense in a rounded-out way. The more meaning, the more reason for selection of this plan.  
Another 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.
It makes sense that the designers had started out with regular squares. Adjustments were then made to create a new layer of meaning.
