An appropriate measuring device. Maybe you should learn about them and determine which ones might have been available to ancient Egyptian craftsmen.
I don't think there is any that the ancients could have used. Certainly not to the micron level. That takes modern tech like a guage sensor or structured light. You can't do it with a ruler. You keep forgetting that the precision lines have to be cut into the object. Measuring is one thing. Cutting to that precision is another.
Now you're beginning to catch on.
And tell me again what was the measuring tool that could be used to know when to stop rubbing. Why grind, rub and repeat 100 times when one or two passes with the lathe will get the symmetry down to the micron level. Thats how we normally do it.
Because they didn't have it, they had to do without.
How do you know. This is denying their ability as ancient craftsman lol. Being creative with tech is just as creative. If someone found a vase from modern CNC machining in 5,000 years they would think this culture was very talented.
That's a bare-face lie and you know it.
Actually its not as it uses the exact same logic as yourself. You object that I am denying the craftsmanship of ancients by suggesting they had modern type tech that helped them achieve the precision. Rather than their unaided freehands as an artist in sculpturing the vase.
Yet you are quite happy to allow that these ancients used other tools like chisels, grinders and some sort of wheel or lathe. The majority of people on this thread acknowledge that the symmetry and circularity in the vases was achieved by some sort of lathing or wheel.
This is the same thing as I am doing except I am taking it one step further and saying they had tools just like you say but just more sophisticated tools to achieve the high precision.
How is this different.
All part of the craft of using hand tools, then and now.
Are you saying that the hand tools such as a chisel, pounders and rubbing achieved the near perfect symmetry and circularity. Or did they get help from some sort of lathe or wheel to ensure circularity.
No, I don't see any logic. What I do see is a dishonest attempt to win an argument by constantly shifting your assertions about what constitutes "tech."
The assertions is exactly what it needs to be. Your saying the ancients were aided by tools and measurements to get the precision and not their bare unaided hands without tools. I am saying the same thing. Just making the tools more sophisticated to match the high precision.
Its logical because everyone recognises that precise symmetry and circularity are an obvious result and signature of a lathe and not unaided hands. The lathe and not the artists unaided steady hand is what gets the precision.
The chisel or grinder is what helps get the shape and not the bare hands. Same thing, the lathing helps get the better shape and not the bare hands.
What you want me to believe is that a human can create a precision machine part without a lathe or any machining. When its a logical and evidential fact that precise symmetry and circularity is the result of lathing of some sort. BUt you want to make a special case for these ancients otherwise we are denying the artistry lol.
