Some really great pics in there! Take a look. Personally I think the two 1,500 ton blocks two stories in the air is really cool. It's possible to move that big slabs, but the logistics are amazing.

The Delhi Iron Pillar really isn't ancient.


The pillar was erected in about the fourth century AD, although some have said that it is about 2300 years old.


But that giant machine is interesting. I can't find anything else on it. The site really should elaborate on where this picture comes from. My first thought was that if it is true that is was dug up, maybe it was a piece of mining equipment that fell down a shaft or something. Some of those machines were huge. Because more info wasn't given, makes me think it's BS.

Andy1972 says:

Anyone whos studied the construcion of the pyramids knows that architecturaly they are more precise than the sky scrapers built with the technology of today..


I don't see how you can say that, since the facing of the payramids has pretty well worn off, so all we're usually looking at is the underlayment. And I don't know if any surveyor has measured the bases, angles, and area of the faces with any accuracy, but I'd be surprised indeed if the accuracies were within a magnitude of three or four as close as a modern building. Do you have any data to back up this assertion?

The pyramid of kheops has bore holes for air at its base that require a pression that is nearly impossible with the diamond point drills they have today...


How do you know this? Do you have any data on the variance of the air holes in the Cheops pyramid? I don't! And I think our drill shafts and bits are quite a bit more accurate than those forged three thousand years ago. Again, where is your data?

"....and the slabs, some weighing upto 3 tonnes, are cut with a precision that is impossible without machinery..and the bare the marks of being cut with a revolving blade cutting at a greater velocity than the cutters we have now..."


I don't see how you can look at a slab and tell the speed of the cutter. Perhaps you'd care to share you background data with us.

"In 1936 ...It is the ealiest form of battery known from more than 2000 years ago.


True, but that's old news, and most researchers today believe it's a great idea that was possibly used in electroplating jewelry.

But that doesn't speak to strange and mysterieus technological breakthroughs in the past; rather that the people of a couple millennia ago weren't exactly neolithic hunter-gatherers!

Don't get me wrong, Andy; I'm not shooting down the abilities of the ancient Egyptians. If you ask any modern aerospace engineer or project manager who the father of his craft is, he'll (assuming he knows his history) likely as not say Imhotep, a true giant of a man.

But there's a big jump between that and mysterious ancient civilizations whose capabilities exceed ours today!

I do not believe that we give our ancestors enough credit. We seem to have a belief that we are as smart as human beings have ever been in the history of the Earth. That may not be entirely true. There are all kind of ancient machines and ancient batteries.

This is one of the best: The Antikythera Mechanism
www.math.sunysb.edu...

It seems that the human race has obtained advance technological states throughout the ages but could not hold onto them. Disease, wars, dark ages, etc. all wrecked not only the machines but the knowledge of the science putting mankind back at the starting point where they would have to learn and discover all over again.

Not relating to the site mentioned here, but here is a website devoted to stoneworking techniques used by the Egyptians:

Link

A lot of the page discusses the use of machine tools to cut stone, as presented as evidence from study of tool marks left on the stone. The precision is absolutely amazing and could not have been done with some form of lost technology.

For example, the author compares trepanning (a hole saw), used to cut granite. A modern stone cutting company quoted today - using diamond tipped saws - they can bore a hole in granite at 900 RPM with a feed rate of .0002" per revolution, but apparently the Egyptians were able to bore a hole at an astounding .100" per revolution feed rate - 500 times faster.

As a machinist, I know a lot about cutting speeds and machining practices, and for one, I don't see any way they could cut stone in the manner they did without machine tools and some form of advanced technology. Even the task of moving large stones is undaunting in and of itself.

Interesting Post :

I'd want to reasearch some of the items mentioned, and get maybe a decent archaeologist's attribution to fully believe it, but I guess these thigs may be possible.

Here's another good site from Smith College:

It's not bad for a college site, but some of their dates are off a little.

Check out the Trepanation Kit, or my personal favorite - the Battery of Baghdad.
