massive jewelry boxes.

The Egyptians were obviously much more advanced and skilled than we give them credit for.

No matter gender, age, cultural heraiage a fedora should be worn along with a slight grimace out of pure respect.

11. Inside corner inside the box

measured with a precession tool instrument.






Think of it as a geometric reality. In order for the lid to be square with the two inside walls, the inside walls would have to be parallel to one another along the vertical axis.


Moreover, the topside of the box would need to establish a plane that is square to the sides. That makes finishing the inside exponentially more difficult.


The manufacturers of these boxes in the Serapeum not only created inside surfaces that were flat when measured vertically and horizontally, they also made sure that the surfaces they were creating were square and parallel to each other, with one surface, the top, having sides that are 5 feet and 10 feet apart from each other.

But without such parallism and squareness of the top surface, the squareness noted on both sides would not exist



The hardness of granite on Mohs scale of mineral hardness is 7 on a scale to 10



copper has a hardnest of 3

Any idea what they could have used to do that?

Also, what materials were avialable for them to carve the granite so precisely?

First, you chisel your slab of stone to a more or less flat state; It doesn't matter that the copper chisel is softer than the granite, it's the force and angle of the strike that fractures and removes the stone chips.

Second, you take more stone - hand-sized granites, in this case - and you either used them to hammer at the chiselmarks, essentially pulverizing the striations away, or you rub them, grinding it away; the former is faster, but the latter produces a smoother finish (hammering with stones is how the Olmec made those stone spheres in Guatemala)

Next, you take your grit. One thing Egypt has always had is an abundance of grits - from coarse gravels, to rough desert sand, to fine beach sand, to the silt from the Nile - plus lots of grades between. You apply wet grit - mixed with water or oil, depending on whether you need long-lasting viscosity or not - and place a beam of hardwood. With two guys for a big project like that outer lid, you work this beam back and forth, adding sand-paste as needed. Every now and then you wash the project off and use a finer grade of grit.The final grade would be river silt or even pulverized stone from the work site, applied with water or oil, though this time by hand.

Essentially, the same as using sandpaper, or a rock tumbler with elbow grease instead of a rotor.

The corners were probably created in much the same way, though obviously with different tools - finer chisels, lighter hammers, etc.

Folks can google "grinding stones for lithography" it if they want to actually see the process in action. I've ground many a stone in my day. Thank goodness it was only limestone and not granite. I assume stonecutters who made granite or marble tombstones used a similar process back in the old days.

archeologists think that this
Collection of Ancient Egyptian mason tools including copper alloy chisels and then hand polish made these pieces without the aid of machine tools



Modern
Engineers and
machinists
dispute this after doing studies, regarding man hours studies and perfections of .0002 of an inch



An Interesting note is
the narrow chamber hosting the 80 ton object... not a lot of room to maneuver people or the block.





Map of the chamber






My question is why such perfection of the inside of box to house a dead bull?

Really is a mystery

They're neat as hell, and I was willing to give him a shot, but once he started off with the wide-eyed "this could not be done by conventional methods!" stuff, I called it quits.

For those unaware, Mehler is essentially the Captain Woo of Egyptian history, and insists that they had super-advanced technology that all just mysteriously vanished in a mysterious cataclysm... Essentially an argument from disbelief - he can't believe that the people of Egypt could make precise angles and flat surfaces, so he comes up with these goofy idea of ultramodern technology that vanishes - all of it, every scrap.

Part of this is perhaps excusable - there's a lot of misconceptions about ancient Egypt, primarily the notion that all the work was done by slaves. Hardly! The men who worked on tombs such as this were experts of their craft - they'd have to be, to get such a prestigious job, fashioning the eternal homes of gods-on-earth. Each of these master craftsman was under the oversight of an even more skilled master, probably someone who had done projects like this several times before.

of course the Egyptians were working with "primitive" tools... but they knew how to use those tools to the best possible result. Also often overlooked is the use of grit, water, and oils in this sort of work. It's really not difficult to get a polish like that; all you need is water, grit, and labor to create the friction. Same as a rock tumbler. The nagles were easy to achieve as well - it's not as if angle tools are a recent discovery or anything.

Another part is... well... prejudice. You run into a lot of woo-woo stuff about Egypt, about the Inca, Maya, and Aztec, about Zimbabwe and southeast Asia... but you never hear these guys talking about how the ancient Greeks or Romans or Cretans "must have" had some hypertech to produce their amazing monuments and buildings; it's assumed that Europeans had the know-how and skill, while the rest of the world are basically monkeys whacking rocks together.

But then, while the ancient cultures to which you refer were creating astounding monuments for the ages, mine were probably still squatting in caves and painting themselves blue.

so the end result is now it looks like a video taken from inside a stone box. Without commentary.
