Astroboy said:The pyramids were probably created with a combination of techniques including counterweights, levers, lubricated tracks, and ramps. Contrary to popular belief there are written texts describing construction techniques and wall paintings depicting the movement of large objects.
If this one man could accomplish these amazing feats of construction by himself using little muscle and mostly creative brain power imagine the capabilities of ancient Egyptians whose obsession with large scale projects forced them to improvise.
Most people don't bother to research the progressive development of construction techniques by preindustrial societies so they tend to believe that these wonderful structures just popped out of nowhere. The Great Pyramid was preceded by several smaller and different pyramid designs which they learned from. They made mistakes in projects such as the Bent Pyramid and learned from them to perfect their techniques on latter designs. The Bent Pyramid was preceded by simpler stepped pyramids.
see link for the Bent Pyramid: Bent Pyramid - Wikipedia, the free encyclopedia
Ancient and medieval builders lacked the mathematical knowledge of structural analysis and had to go on intuition and experience. This means they often made mistakes and their buildings cracked or outright collapsed. The Bent Pyramid is a perfect example of trying to correct a mistake in the middle of construction. See the link above for explanation. Europeans who attempted to build progressively higher and higher gothic cathedrals also made many mistakes and some of their ambitious designs fell down. Over time they learned how thick masonry walls needed to be to support certain weights and came up with several ingenious techniques including flying buttresses to counter the lateral thrust of their high walls. You can see this at the Notre Dame cathedral.
What is truly amazing is how good experience and intuition can be for ancient builders. Structural analysis of the flying buttress systems developed for buildings such as Notre Dame show that the flying buttresses have just the right amount of taper and thickness along the length to match the structural loads their were carrying. This was all done without computers and sophisticated math. Of course it did take the collapse of buildings and the deaths of many workers before they got things right.
Tony2013 said:Well, perhaps. It's feasible, but it doesn't answer every question, and there are a lot of them.
Tony2013 said:For example; the straightness of the Descending Passage, which over its full length only strays from a perfect line less than 7 millimeters.
Tony2013 said:Or the precision with which the outer limestone layer was cut, to the point that, according to Herodotus in 440 BC, you could barely make out the seams when viewed up-close.
Tony2013 said:From there, we move on to the question of the pyramid's correlation to astronomy, which I highly recommend you dig into if you have not already.
Tony2013 said:This doesn't even take into account the litany of personal experiences individuals have experienced at the pyramids.
Tony2013 said:Believe me, there's a lot more to the question other than just "They practiced for a while, then they got it right."
Tony2013 said:Astroboy, I would love to pick your brain about this stuff. Sounds like you've got some really impressive experience... are you an architect, historian? I'm a Lit. major who has read a bunch of stuff, so in that sense I wouldn't pass the Ascham litmus test.
