Retracing Khufu's great pyramid. The "diamond matrix" and the number 7

Abstract

The geometry of Khufus Great Pyramid at Giza is even more sophisticated than perceived at first glance. From the first aerial photographs from the 1920`s, it became clear that the pyramid was not set on a square base, rather it has a diamond or star shaped plan, a fact that is overlooked or avoided in the abundant research literature concerning this pyramids advanced geometry. Most pyramid building theories deal with only its physical erection, but from an architects perspective, the first question would not be how to erect it in practical terms but how to develop a system (building grid) enabling the details and precision of the project to be communicated to a workforce of, for example, 10,000 illiterate men.
This paper aims to show how and why the building grid for the last remaining of the seven wonders of the ancient world was developed with the help of the prime number seven. As discussed herein, this was achieved without involving any advanced mathematics. Most importantly, the invention of the building grid represents the separation of the buildings measuring system from the buildings constituent parts.
