Rather than approach from a position of π, one could equally address the problem from the stance of φ.
The 5 1/2 seked, which is a 5 palms + 2 digits run to a rise of 7 palms also naturally incorporates the phi ratio, √φ = 14/11.
From this perspective, it appears that at the end of the reign of Snefru [Meidum}, during the time of Prince Khufu, this three-fold relationship was among π, √φ and seked 5 ½ may have been implemented into monumental architecture for the first time.
If true, how long had the knowledge of this ’divine relationship’ been known to the caste of priestly architects?
