INTRODUCTION

For the past 5000 years, the system put at use in the erection of the great Egyptian Pyramids [2] remains a mystery. None of the various theories put forward until this day are fully satisfying from a builder's point of view. And modern technology and technique are about as ineffective.
From Antiquity on, two interpretative models are opposing each other: "mechanical" theories, starting with Herodotus [3] against "ramp" theories following Didore of Sicily [4].

Frontal ramp Helicoidal ramp Engaged ramp

Frontal ramp simulation in situ

None of those theories are offering satisfying evidences to the architect/engineer/practitioner because, before being an archeological and egyptological object, pyramids are, essentially, a built edifice, a civil and architectural piece of engineering. the logic of which remains the same: economy of effort and means, technological development and structuring of tasks.

Lever arm on tripod suggested by J.P. Adam, if the principle and the scale seem accurate, the counter-weight could be "living" workers used as dead weight!
