As I have shown in Part 1, concepts like φ or π did not belong to ancient Egyptian mathematics and therefore could not be used by the ancient Egyptian architects. Their presence in the plans of ancient buildings is mainly due to our modern interpretation of the geometrical figures that compose the plan on paper. However, I am not arguing that mathematics was not involved in ancient Egyptian architecture, but rather that so far we have analysed cases in which the wrong mathematical system was adopted. Before we move on to an analysis of the ancient Egyptian architectural documents on planning and building, we must consider a final point: the supposed existence of a secret knowledge, restricted to a few initiated, concerning rules and symbolic meanings that would have been hidden in some buildings.

In theory, a project might be laid out on the basis of extremely complicated concepts and then the actual construction carried out with a certain degree of approximation. It is also true, however, that ancient Egypt does not reveal evidence for this discrepancy (in fact, I wonder how many other cultures actually do?). At any rate, the total lack of evidence has never prevented people from suggesting more or less complicated theories. Architecture may have a strong symbolic function, and in theory it is possible to suggest that, in their buildings, ancient Egyptian architects hid meaningful mathematical relationships, not immediately perceptible and related to an esoteric knowledge. Such a hypothesis is extremely difficult to test.
