My last posting mentioned John Neal’s creative step of *not *averaging the Great Pyramid of Giza’s four sides, as had routinely been done in the past – as if to discover an idealized design with four equal sides. Instead, Neal found each length to have intensionally been different. When multiplied by the pyramid’s full height, the length of four different degrees of latitude were each encoded *as an area*. The length of the southern side is integer as 756 feet, and this referred to the longest latitude, that of the Nile Delta, below 31.5 degrees North. Here we find that the pyramid’s reduced height also indicated the latitude of Ethiopia.

The actual height of the pyramid is 440/441 of its ideal (pointed) height since the top pyramidion was missing. This reduced height is 480 feet or 440 Sumerian feet, hence indicating the intended feet were those called Sumerian, of 12/11 feet. This ratio, 440/441, is the ratio between the polar radius of the Earth and its mean radius, implying that the Great Pyramid came into existence to record the results of a geodetic survey similar to those of the 19th century, which resulted in a similar size and shape for the Earth as the ancient Model of the Earth. Such surveys must measure a set of degrees wide enough to capture the shape of the earth from the northern latitudes to the Equator. For instance, the French survey went to French Guiana in South America, which is 5 degrees north of the Equator.

If the actual height of the pyramid is multiplied by the southern side length of 756 feet (figure 1), the area is 362880 feet; the degree length 10-11 degrees of the Ethiopian highlands, north of the capital, Addis Ababa. This can be seen on page 113 of *All Done With Mirrors* (2000), Neal’s primary text. My adaptation is figure 2 below.

The variations of English feet are shown, these required to convert each degree length to an assumed standard of 360,000 feet. This led to ancient metrology’s micro-variations of the English and other feet as well as being able to maintain integers between the radius and perimeter of circular structures. In this case, the Ethiopian length of 362880 is 360,000 feet of 1.008 (126/125) English feet, a module better known for a number of Greek feet, this foot being associated with Olympia.
