The Geometric Design
of the Great Pyramid

by David Furlong

A consideration of the Geometric Design of the Great Pyramid
Taken from the book The Keys to the Temple by David Furlong

This article looks at the possible geometric design that can be shown to underpin the constructional element of the Great Pyramid. There are no textual plans of the pyramid contemporary with its construction so that any such design scheme must remain speculative. This design is taken from the book The Keys to the Temple.

Triangles in Solid Form
There have been different reasons put forward as to why the Egyptians chose the pyramid as a monument. One of the most common is that it reflects the rays of the Sun. Whatever the reason for the Egyptians to have worked with pyramids in stone they would need also to have worked with them in plan form as triangles. Sooner or later they would have realised some of the key properties of the triangle, such as the equal sides and angles of an equilateral triangle. Much of the internal geometry of the the Great Pyramid is based on this triangle.

Pyramid 1

Step 1: Draw an equilateral triangle SXY on an extended base line AB

Pyramid 2

Step 2: Construct two equilateral triangles QST and RSR on common base ST. Draw line QR.
Pyramid 3

Step 3: With radius QR draw arc to line AB at N. With radius RQ draw an arc to cut line AB at M. Draw line SN and SM. Triangle SMN equals the cross-section of the Great Pyramid.
Pyramid 4

Step 4: Draw a circle centre O and diameter ST. With radius SC inscribe an arc to cut ST at Kc. Point Kc sets the level of the King's Chamber. Line Kc Y sets the alignment for the Grand Gallery.
Pyramid 5.

Step 5: From points P1 and P2 draw "vesica" circles with radius P1Q and P2R. Both circles will by definition pass through points S and T. Where circle centre P2 curs SN at point E marks the position of the pyramid entrance and the start of the descending corridor.

Step: 6 The position of all chambers plotted in relationship to this basic design pattern.

It is the suggestion of this article that once this design form had been the created then the more usual process of establishing a design grid, familiar in drawings and carvings would then have been created. As has been shown in the article on sekeds, these were definitely woven into the design matrix of the pyramids. For example in the pure geometric form of the above design, with a base of 440 cubits the finished height of the pyramid is a fraction under 280 cubits. Practical building requirements would demand that this be rounded up to 280 cubits to fit the seked requirement.
