Uvo Hölscher is an Egyptologist and German architect. He has stated for the first time the lateral ramp theory for explaining building construction such as Chephren pyramid. Unlike Flinders Petrie or Ludwig Borchardt who preconceive frontal ramps, Uvo seems to have imagined to put ramps along faces of internal massive of pyramids. Sadly it has been reproached two things to its lateral ramp theory:
* First reproach made to Uvo Hölscher are the strong slopes enforced to the ramps that can spread only along the faces. That is the reason why this theory has been accepted only to explain building of small degree pyramids. After that, new theories appeared such as lateral ramps with extensions, semi internal ramps, spiral ramps or internal ramps. These theories prefer gently slope ramps. As it has been demonstrated, it is more efficient to use strong slope ramps and even better to lift blocks along Walls, so first reproach made to Uvo Hölscher is no more valid.
* Second reproach made to Uvo Hölscher is that the presence of lateral ramps such as imagined by him forbid final coating installation, because its ramps are temporaries in bricks, since they exceed the angle of the slope. Our solution: we consider surrounding ramps, part of the pyramid and not exceeding the angle of the slope. Unlike Uvo, these ramps should be not removable, made of stones and not of raw bricks.
Following illustration shows such kind of ramps… but keep in mind that the use of these ramps should be for the first meters (54m roughly)!
