"i wonder what tools they used?"

Good Question.

Palistinians? ;-)

Damascus steel? - nope too early

"Metalsmiths in India and Sri Lanka perhaps as early as 300BCE developed a new technique known as wootz steel that produced a high-carbon steel of unusually high purity.

I suppose they could have used bronze and iron chisels, especially on softer rock. There are also references to building a fire to heat the surface being excavated and then splashing water on the surface to fracture the rock.

Thanks, Fred Nerks. Interesting. Just imagine all that work without our modern tools.

In the former Roman province of Syria (located in modern day Jordan), researchers are currently studying a sensational canal system. It extends mostly underground over a distance of 106 kilometers (66 miles).

[Fred Nerks]

Why is it dry now?

good question, the article doesn't appear to answer that.

:’) Thanks Fred Nerks. The Romans had it goin’ on.

The wall won’t stop anything,gee you think China built a wall for nothing?

Note: this topic is from 4/19/2009, and it is a re-ping, because it's just so darned interesting. Thanks again Fred Nerks.

The wall won’t stop anything,gee you think China built a wall for nothing?

Actually, yes, it was largely for nothing. Architecturally, it was a huge achievement. Militarily, however, it was a total failure.

[null and void]

I guess that’s how long it will take America to erect a wall at the Mexican border?

Our government will build its wall in a matter of months, just as soon as they need it to keep us in.

It's what communist dictatorships do.

[Bigg Red]

Very interesting, indeed. A lot of engineering genius in the Roman Empire.

[BenLurkin]

they loved to waste massive quantities of water

What a ridiculous comment!

[Mr. K]

ok now how do you dig tunnels like that without lights?????

this is freaky

[Mr. K]

That sounds like a democrat idea

[Jane Long]

Rich senators refreshed themselves in private pools and decorated their gardens with cooling grottos.

Sounds familiar....history IS repeating itself.

[Vaduz]

Agree we are only a few steps away from a dictatorships.

[MattinNJ]

Well, that goes without saying
