Reading is my primary way of getting information. Documentaries take too long for information and they tend to be biased, I learn't that very soon in my degree and stuck just to the designated textbooks. I have cognitive dissonance in this area, having read one book from a Roman historian about these, and another from an historian that dated them at 4000-8000BC. In my mind, the Roman historians evidence was circumstantial and the other books evidence was much more empirical when it came to stone-masonry and the potential cultural architects of the stones. We have not even gotten into that part though, I am still waiting for a) a complete model to be proposed by someone, that has any evidence of it being used b) A model with specifics that I can actually apply physics and maths to to see if it works. Geemack is still keeping his top secret solution top secret, so it's more a waiting game for his easy 'one minute solution with six people', at this point. Since another user kindly worked out some data on the properties of wood I was able to expand the model and test it's veracity. But no one else has given a model, just a few words and ideas. I'm stumped for ideas, the canal idea is redundant the stone is too heavy (I worked it out) and the pig fat idea is a nice idea but has yet to be applied to a mode of transportation for me to factor in what effect the lesser friction would actually have. |

I gave you an example of the 'Pig Fat' idea It is used to launch Ships.
Examples have been given of stones being moved hundreds of K by Romans. They moved stones of hundreds of tones by ship. Roman artifacts have been found under some of the stones at the temple. Why is it so hard to think that the Romans slid them down the hill? |

The impression I got from reading this is that they excavated the temple of Jupiter.
Quote:
That is the roman temple that was built on it's foundations. Unsurprising everything they found was roman. Are there pictures or more details of this expedition?
Quote:
That would be a brilliant resource, I remember reading excerpts from the second book I read on the subject of the triliton but can't seem to find a translated version online.
Quote:
I have. The case of the main structure below the temple of Jupiter is not as straightforward as it first appears.
Quote:
I don't want aliens to have anything to do with this thread, and most of the arguments in it are "Aliens could not have warped here" due to x. Which renders it as preaching to the converted. |

Hello Mister Earl.
Can you write which one you think most likely, and then we can examine and model it with basic mechanics and physics. |

I see no point in listing which I think is best, given you've already dismissed them out of hand. I'm much rather you tell us what you think it was, so we can figure out why you're so dismissive.

Why not?
I haven't dismissed any out of hand. I have just done the science for two of them and shown them highly unlikely. Other people can either point out where I went wrong in my analysis, or they can propose other novel solutions for people here to examine. Show where I dismissed one out of hand. |

Like the pig lard on stone tracks?
#EDIT: Again I ask what your hypothesis is. I really get the impression that you have your own idea, but have not shared it yet. |

That is the one I have yet to look into. The reason I have not commented on it up till now is that we see no evidence of smooth stone tracks between the quarry and the structure, so it seemed unlikely and other possibilities people suggested seemed more likely to address first. Although looking at the historical records for cultures that used this technique and why they used it might be fruitful, as will finding out what the coefficient of friction for stone with fat on it is. |

You just made a mistake on the last one, that would be for 0.25% not 0.01% In reality though considering geometrical constraints on the rollers, to be practical they would have to be as near to perfectly circular as possible. If they were perfectly circular then your 0.01 number would be more close to the truth, and the psi for that would be 165,000 psi. |

Or rather 165,000/n
Where n is the number of rollers. |

So which organisations did you contact to find out how much weight can be supported by wooden rollers?
Did you contact archeaologists to inform them Romans (or anybody else) could not use them? Presumably including those who have used rollers to move heavy objects in living memory? |

I know. And since the wood will be crushed a small amount the contact surface will lower the weight of the stone, and require a lot more force to move it laterally, which was the whole point of my previous calculation and the PE involved in needing to overcome this elastic deformation. In reality the model is far too simplistic and ideal, as the psi stated is for an ideal wood, when in fact wood is anisotropic meaning that its structure and properties vary in different directions. For all intents and purposes if the force is applied evenly wood is an elastic material, which can bend in certain specific directions without breaking. check out the youngs modulus of wood. At it's elastic or proportional limit when a force as large as the one we are talking here is applied the wood will go back only partially to its original shape or crack the whole log. |

Is there a point you're trying to make here, Zeuzzz? We know the rocks were moved. We know the sort of technology available at the time. We can put forward possible explanations as to how the rocks were moved. We probably cannot, short of inventing time travel, ever know for certain exactly which methods were used. So what? And if you're not happy with the explanations some people have put forward, so what? Your personal incredulity is irrelevant to everyone but you unless you've got some new evidence to bring to the table.
So, to summarise: what do you want? |

A model that works, scientifically. I'm waiting for Geemacks model he's been keeping up his sleeve for so long and been so vocal about in this thread. You can wait with me if you want. Any plausible model that holds up to scrutiny is fair game.

Maybe we should look up the amazing engineers that built the giant hill afterwards.

You can't see the triliton in those pictures, they mean nothing. Just look at any contour map of the area.

Maybe you should read the thread? I would help if my original post had not been deleted completely. The old structure that the Romans built the temple of Jupiter on has stones of extremely similar dimensions and properties as the one left in the quarry you showed above, where they were all mined from. There is a considerable distance between the two, and also a considerable height for them to have been lifted and put in place with a precision so accurate that you can barely fit a razor blade in between. ![]() See the person for the scale. What have you thought this thread has been about? The existence or non existence of a random hill next to the pregnant stone?! Really?

As the pregnant stone has never been moved let's calculate it again but for the Trilithon Stones:
length: 19.6 m Width: 3.65 m surface: 19.60 m x 3.65 m = 771.6 in x 143.7 in = 110878.92 sq in Weight 800 tonnes = 1763700 lbs flat psi 1763700/110878 = 15.9 psi Contact surface: 10% : 159 psi 1% : 1590 psi 0.5%: 3180 psi 0.25% : 6360 psi and 0.265% : 6000 psi If red cedar has a compressive strength of 6,020 psi, the contact surface must be at least 0.265% of total surface to avoid the wood breaking: 19.60 m x 3.65 m x 0.265% = 1.9 m2 If there are 40 rollers with a diameter of about 0.5 m (remember that the length of the stone is about 20 m) the contact surface per roller must be at least: 1.9/40 = 0.047 m2/roller The length of a roller is 3.65 m so the width of the total contact surface per roller must be (at least): 0.047/3,65 = 0.013 m = 0.51 in ( about 0.8% of the circumference of a roller...) Taking into consideration the relative elasticity of the wood, the diameter (19.68 in) and the cicumference (61.8 in) of a roller, it seems coherent IMO. |
