Actually, the whole of edifices made of earth or stone, since the Neolithic era: cairn, tumulus, dolmen, fortified enclosure,
|Cairn in Barnenez (religious engineering)||threshing area in Cipierre (rural engineering)|
As a matter of fact, this method is, from the start and by essence, anthropometrical, picking stones out of a pasture or a farming field generates a pile of stones which must be raised by hand, in order to take as little space as possible, the roughest stones are put inside facings made out of the nicest
A man's height is the anthropometrical limit. Then if you want to increase the heap, you have to add a peripheral facing on which to climb in order to continue to raise the edifice until one more man's height is reached , and so on and so forth. This method is called by us “accretion-raising” because only peripheral accretion allows to raise the heap; it explains A.Choisy's schema of construction by degree and imposes the concentric facings and the ascending degrees on these edifices.
This method was applied to the Egyptian step-
A computer simulation of this method was done and can be applied to every step- pyramids. It allows to surmise that, whether they are small or large, solar temple or pyramid, they represent more or less advanced stages of a similar project. On the contrary, the Pyramid of Houni-Snefru in Meidoum and the Sekhem-khet both qualified as “unachieved” are nothing but in two more or less advanced stages of their destroying (schema).
And up to the way of thinking, the cosmogonic, theogonic and anthropogonic perception and representation of the world, as also the numerical notation of the growing arithmetic according to G.
It is even possible to suggest, considering the conjunction of the realisations, that construction could have participated, or else generated the structuring of writing and of arithmetic.
