Now that we have gone back to images of cuts in rocks here is a statue of Bahubali one of the largest free standing monolithic statues carved from granite and completed around 980 AD.
(The fig leaf is a modern day construction not to upset conservative Christian sensitivities).
I'm more impressed that they managed to cultivate such a plant with the perfect foil lol. They could have at least done it in stone to keep in line with the statue.
How do you know that even in 980AD that this culture had knowledge in their own way besides pounding and rubbing for years to achieve what they did.
Though big and impressive it pales into insignificance at some of the early Egyption feats. The pyramids dwaft this status for one and its not just one piece of work by 100s together as part of that one works.
That ain't granite but composite quartzite which is far harder to work with than granite. Its a stone calvers nightmare in stone shaping. The statue itself is 1,000 tons. But the block it comes from would have been around 1500 tons. They had to transport this up river some 500 miles from the quarry. We have problems moving 100 ton loads with heavy lifters and trucks.
Now lets look at the technological development of iron and when it became hard enough to cut through or shape granite without the use of abrasives.
| Period | Material/Technology | Hardness (Mohs) | Could cut granite w/out abrasives? | Notes |
|---|
| < 1200 BCE | Bronze | 3–4 | ❌ | Used abrasives (sand + copper saws) |
| 1200–600 BCE | Wrought iron | 4 | ❌ | Slightly tougher, still too soft |
| 600–400 BCE | Early carburized steel | 5–6 | ⚠️ Limited | Could peck, not slice granite |
| 18th century | Crucible steel | 7–8 | ✅ | First reliable granite chisels |
| 20th century | Tungsten carbide / Diamond | 9–10 | ✅✅ | Industrial stonecutting era |
Using the 'logic' employed in this thread based on the fallacies of argument of personal incredulity and argument from ignorance,
Do you have to add such personalised rhetoric lol. Just state the facts. This is a sure sign that someone is more invested than just the science and facts itself without even determining whether the facts are correct or not.
even though the carvers of the statue had access to iron tools, the tools were not hard enough to cut directly or shape granite, the technology only became available in the 18th century with the development of crucible steel which is carbon hardened.
Therefore your logic is even though the signatures clearly look like modern signatures they somehow hand crafted these signatures without any tech at all.
We are talking on par if not superior shaping and cutting of the most hard stones 5,000 plus years ago. Some in composit quartzite.
Not just that we can cut all the crap of these being made by pounding, grinding and rubbing by once again the signatures on the works like statues and other works such as the image of obeliskes with circular saw overcuts in the works themselves as part of creating them. In this case clear circular saw or some sort of saw capable of cutting the entire base of this statue into its thight and overcutting what is one of the hardest stones.
Like the vases we see the superior work of the earliest Egyptians compared to later works such as this precise leg and knee of a statue of pharoah Khufu compared to a later statue from Ramses II.
The Ramses statue does look like it was hand chiseled and roughly made. Theres little fine detail, quite a rough and unpolished finished.
So therefore they must have used some unknown super technology like the predynastic Egyptians, in fact every cut mark in granite, a granite block or statue that was produced before the advent of crucible steel in the 18th century must have been produced using this super technology which then disappeared without a trace.
Most of the precision works and I mean precision and have actual modern looking signatures in them are from the earliest dynasties or predynasty. There are some works that are amazing that come later but there is still question over their origin just like the vases. They may also date back to the earliest times.
Nevertheless this is not denying that there may have been some knowledge that was preserved in some limited way within later dynasties. But the vase majority and the best examples come from the earliest times. Which at the vesy least is coming from a time that is suppose to have less tech compared to later cultures who had the wheel, even sophisticated wheels and laths, logistics, and various metals and developed tooling.
An obvious question which arises why did this super technology disappear only to be replaced by a major backwards step in technology in using crucible steel?!!
Because the westernised idea of knowledge and tech being a slow and gradual evolution from simple to complex or simple to better techniques through the accumulation of knowledge is a forced idea about what knowledge is.
The whole point of this thread is that knowledge and tech may have peaked and fallen many times and was lost and restarted in different ways. That ancient cultures peaked in their own kind of knowledge different from today and then collapsed for various reasons. If there was a massive catastrophy that wiped out most of humankind today.
In 5 or 10,000 years we could say some of that knowledge was lost and we had to start again to gradually build up to a level of knowledge which may be different to how knowledge was understood in the past.
This may happen in smaller examples where localised knowledge peaks and falls and peaks and falls in different ways. Sometimes some still having that knowledge while others did not. Its a continually peaking and falling phenomena and not this fixed westernised materialistic and scientific idea of simple to complex.
Here are the facts abrasive cutting went well into the 19th century using a sand and water slurry like the ancient Egyptians had used in combination with copper saws thousands of year earlier.
Except the signatures are completely different. Copper saw of copper tude and sand abrasions don't cut. They abrase and thus a usually not sharp and thin or leave sharp planes in cuts like electric planers and routers.
This is the orthodoxy that is being challenged by the tests and the out of place signatures that clearly do not have the same witness marks as copper and abrasions.
Works such as the statue of Bahubali are a testament to craftmanship not technology.
Therefore there was no lathe, or wheel which produces good circularity. No one is saying there was no pounding and rubbing. Especially rubbing and polishing. They are the final stages. We are talking about the cutting and shaping of the hardest stones. I mean some of these cuts would need to be 50 foot long and 12 feel wide. Thats a massive copper saw.
Good old pounding and rubbing can explain even impossible feats that are well recognised that can only be achieved by tech. In some ways your doing what you protest the whackos. By appealing to such unreality as though humans can rub precision tools into existence without any help from tech.
