Figure 2: Where it all began...for the builders of Stonehenge or, by consequence, those who set out the astronomical structures of Megalithic New Zealand and other regions of the South Pacific. The measurement standards, which built these magnificent edifices are the same as those which built Stonehenge. The special coded information inherent within the pyramids is, likewise, the same as that found within the geometry of Stonehenge.

Stonehenge incorporates codes found in the exterior measurements and angles of all 3 main pyramids of the Giza Plateau and in many respects is far more complex and difficult to decipher than the pyramids, which were its inspiration. Although Egyptologists cleave to the view that Stonehenge preceded the pyramids, evolving research would indicate the opposite to be true and shows that the pyramids are,clearly, thousands of years older than Stonehenge.

To demonstrate how various locations within Stonehenge are working, it will be necessary to refer back to the individual codes of the 3 Giza pyramids on a regular basis, so we'll commence by extracting those codes first.


Figure 3: The Great Pyramid was built to very exact tolerances, but was designed to be read according to 3 separate numerical systems. Its exact dimensions were 756 feet long and 168 Megalithic Yards (of 32.360678 inches each) high. This was the vertical height to the top surface of its flat altar floor (this pyramid never had a physical capstone, although a symbolic one sometimes featured in the design calculations for the extraction of additional codes. The other two pyramids, Khafre & Menkaure had capstones and rose to pointed tops).

The perimeter length around the base of the Great Pyramid was designed to represent 1/2 of a minute of arc for the ring of the Earth. Inasmuch as 3 separate and slightly different geodetic systems were in common usage, the Priest/ mathematicians assigned marginally different perimeter codes to the Pyramid when working in either the PHI based or "11" series geodetic, "ring of the Earth" systems. Similarly, the vertical height was exactly 453.049492 feet (280 PHI feet or 168 Megalithic Yards) but this could also be symbolically read as 453.6 feet (sexagesimal geodetic system) or 453.75 (11 series geodetic system).

(1). The length of the Great Pyramid was read, variously, by the Priest/ mathematicians as either:
(a) 755.0824867 feet (PHI based...280 Megalithic Yards of 32.360678 British Standard inches each);
(b) 756 feet (sexagesimal/ septimal...280 "rounded" Megalithic Yards of 32.4 British Standard inches each).
(c) 756.25 feet (11 series...275 increments of 33 British Standard inches each...2.75 feet X 275).

(2). The vertical height of the Great Pyramid to the top surface of its altar floor was read, variously, by the Priest/ mathematicians as either:
(a) 453.049492 feet (PHI based...280 PHI feet of 12 PHI inches or 1.6180339 feet each, equal to 19.4164068 inches).
(b) 453.6 feet (280 "rounded" PHI feet...1.62 feet or 19.44 inches).
(c) 453.75 feet (275 increments of 1.65 feet each...19.8 inches).

(3). Under the concept of 3,4,5 triangulation, if the "adjacent" is 3 parts then the "opposite" will be 4 parts and the "hypotenuse" will be 5 parts. In 3,4,5 triangulation the "adjacent" will always be 1.6666666 in ratio less than the "hypotenuse" and the "opposite" will be 1.25 in ratio less than the "hypotenuse".

(4). If the base length of the Great Pyramid were read according to its PHI assignment as 280 Megalithic Yards, then the ratio of 1.6666666 less than that would be 168 Megalithic Yards, (453.049492 British Standard feet). This means that two components of 3,4,5 triangulation are, literally, represented in the length (hypotenuse) and height (adjacent) values assigned to the Pyramid. The third value (opposite) would equate to 224 Megalithic Yards under the Pyramid's PHI assignment.

Alternatively, by reading the Pyramid's base length (hypotenuse) as 756 feet, under the 3,4,5 triangulation rule, the height (adjacent) should be read as 453.6 feet and the symbolic "opposite" as 604.8 feet.

If, in addition, the base length was read as 756.25 feet, then under the 3,4,5 triangulation rule the height would need to be read as 453.75 feet and the "opposite" as 605 feet. Each of these 3 sets of measurement codes was assigned to the Great Pyramid and exploited mathematically. This truth is glaringly evident in the numbers that recur continuously in astronomical structures worldwide.

(5). The literal dimensions of the Great Pyramid were, undoubtedly, 756 feet of base length (standard measurements) and a PHI height of 453.049492 vertical feet to the surface of its altar floor. The Pyramid also had a side face angle of 51.84 degrees. Under such circumstances, trigonometry dictates that the length of the top floor had to be 528 inches or 44 feet (176 feet total perimeter...reminiscent of the British Standard mile's 1760 yards of length). The altar floor dimensions, in conjunction with the 3 varied height assignments, leads to an understanding as to why the Egyptian rods hovered around 20.6 inches.

(6). Under the 3 possible assigned heights, 453.049492, 453.6 or 453.75, the value is divided by 1/2 the top floor length value in feet to divulge the coded size of the "rod" in inches.
Let's suppose that a Priest/ mathematician needed a mnemonic device to use as an aid in remembering the coded circumference of the Earth. Suppose the Priest wanted to remember the 3 varied geodetic, Earth navigating, systems in general usage. If the rod could be assigned a true length of 1/264th (264 is 1/2 of 528) of the 3 possible Pyramid height assignments, then the numbers derived could be easily translated into a mile (5280 feet) figure to identify the Earth's size under each of the 3 geodetic systems. All that was needed was to multiply the length of the rod by 1200 and the set of numbers, describing the Earth's size in miles, would be known. It would have worked like this:

(A). 453.049492 (actual height...used for measuring the Earth by PHI values) 22 = 20.59315873...X 1200 = 24,711.79047 (read as miles).

(B). 453.6 (symbolic sexagesimal and septimal height, for measuring the Earth, primarily, in degrees, minutes and seconds of arc) 22 = 20.61818182* ...X 1200 = 24,741.81818 (read as miles).

(C). 453.75 (symbolic, "11 series" height for measuring the Earth in leagues, miles and furlongs) 22 = 20.625...X 1200 = 24,750 (read as miles).

The Egyptian common cubit rods would have been exactly 1.1666666 in ratio less to their Royal Cubit counterparts. Therefore, the PHI rod of 20.59315873 inches would have a companion rod of 17.65127892 inches.

The sexagesimal / septimal rod of 20.61818182* inches would have a companion rod of 17.67272728 inches.

The "11 series rod of 20.625 inches would have a companion rod of 17.67857144 inches.

This means that the shorter, so-called, common cubits were really only used as mnemonic devices for determining the circumference of the Earth in miles and their complex numbers were only recalled by using the memorised, step by step, formula, based upon 3,4,5 triangulation principles.
Each of the common cubit rods determined that the ring of the Earth was 16,800 miles X the number derived from the "foot" value reading of the chosen rod

*In his book, Ancient Metrology, Donald. L. Lenzen gives the following values for Dynastic Egyptian Royal Cubit rods in Museum collections:

(1). In the Louvre Museum in France is a Royal Cubit measuring rod of Amenopis I, B.C. 1546-1526, described as being made of wood and in excellent condition. Its exact length is...20.670 inches.

(2). The lengths given for 3 Royal Cubit rods of the Turin Museum collection are published as...20.578 inches; *20.618 inches & 20.658 inches.

(3). Lenzen mentions an 18th Dynasty "Double-Cubit" rod found at Karnak, which is 41.30 inches in length. This would place its "Royal Cubit value at 20.650 inches.

(4). Lenzen's estimated averages for the Dynastic common cubits, based upon Pyramid surveys, are between...17.65573 to 17.70* inches (see Ancient Metrology, by Donald. L. Lenzen, pgs. 55 & 56).

There are only marginal variations in the official lengths of these rods from that required for calculating the three mile geodetic measurement systems, applied to the ring of the Earth The length given for one of the rods of the Turin collection (20.618 inches) is exactly correct for calculating the "mile" size of the Earth under the sexagesimal/ septimal system (24,741.81818 miles 1200 = 20.61818182).

It's possible that there was a "lunar year" rod of very close to Lenzen's proposed *17.70 inch length for some common cubits. The Khafre Pyramid shows that its ancient builders set the lunar year at 354.375 days. Half of 354.375 = 177.1875 and a rod of 17.71875 inches would be a practical device for fixing the lunar year duration into memory.


It has been shown that the Great Pyramid's base perimeter was read to any one of 3 values and that each value translated into an individual geodetic system. The systems were in increments of either PHI, sexagesimal/ septimal readings or a simple, whole number league system based upon the number 11.

The most obvious reason as to why the ancient architects designed the Pyramid to have a flat floor top with a side value length of 44 feet was to create a calculation key for remembering 1 degree of arc for the world, rendered in miles of 5280 feet. This is how each system worked:

(1). When viewing the base length of the Great Pyramid according to its PHI reading (280 MY per side) the perimeter value is 1120 MY of 32.360678" each or 3020.329947 feet. If this is divided by 44 feet (the length of the flat floor altar top of the Great Pyramid), the total equals 68.64386242. This value, read as miles, would be 1 degree of arc for the world under the PHI geodetic system.

(2). When viewing the Pyramid as having a length of 756 feet (the true length) the value of the perimeter is 1120 rounded MY of 32.4 inches each or 3024 feet. If this is divided by 44 feet, then the total is 68.727272 and, in miles, this number represents 1 degree of arc under that geodetic system.

(3). When viewing the base as having a length of 756.25 feet the perimeter value is 3025 feet. If this is divided by 44 feet, then the total is 68.75 and, in miles, this number represents 1 degree of arc under the 11 series geodetic system. This 3rd system was specifically designed to deliver up whole number increments in leagues, miles, furlongs, chains, rod/ perches, fathoms and links and was, clearly, the most popular system for mariners and ocean navigators. Excellent grid referencing of the Earth sphere could occur under this system, without recourse to very difficult, cumbersome, fractionated numbers.
