Now this makes more sense than a barrel full of sensible stuff. People have been arguing about how those crazy Egyptians built the pyramids for, literally, thousands of years. Now some French dude thinks he’s got it sussed out:
A radical new idea has recently been presented by Jean-Pierre Houdin, a French architect who has devoted the last seven years of his life to making detailed computer models of the Great Pyramid. Using start-of-the-art 3-D software developed by Dassault Systemes, combined with an initial suggestion of Henri Houdin, his engineer father, the architect has concluded that a ramp was indeed used to raise the blocks to the top, and that the ramp still exists–inside the pyramid!
The theory suggests that for the bottom third of the pyramid, the blocks were hauled up a straight, external ramp. This ramp was far shorter than the one needed to reach the top, and was made of limestone blocks, slightly smaller than those used to build the bottom third of the pyramid. As the bottom of the pyramid was being built via the external ramp, a second ramp was being built, inside the pyramid, on which the blocks for the top two-thirds of the pyramid would be hauled. The internal ramp, according to Houdin, begins at the bottom, is about 6 feet wide, and has a grade of approximately 7 percent. This ramp was put into use after the lower third of the pyramid was completed and the external ramp had served its purpose.
The design of the internal ramp was partially determined by the design of the interior of the pyramid. Hemienu knew all about the problems encountered by Pharaoh Sneferu, his and Khufu’s father. Sneferu had considerable difficulty building a suitable pyramid for his burial, and ended up having to construct three at sites south of Giza! The first, at Meidum, may have had structural problems and was never used. His second, at Dashur–known as the Bent Pyramid because the slope of its sides changes midway up–developed cracks in the walls of its burial chamber. Huge cedar logs from Lebanon had to be wedged between the walls to keep the pyramid from collapsing inward, but it too was abandoned. There must have been a mad scramble to complete Sneferu’s third and successful pyramid, the distinctively colored Red Pyramid at Dashur, before the aging ruler died.
Well, yeah. And, he’s got the evidence:
A microgravimetric survey done in the 80s revealed what looks like a blocky spiral on the inside of the pyramid. Pretty cool. Read the whole thing, here.
