Archaeologists Are Reconstructing the 'Invisible' Technologies of the Stone Age

I had one of the best sleeps of my life on a bed of soft sand, in the curve of a dry creek that I really should not have slept in due to flash flood risk. Since then I've wondered if ancient people might have made mattresses of sand, but they were so simple and evanescent that they left no trace.

There is a great quote:

"The Egyptians built using stone but wrote day to day on papyrus.

The Sumerians built with mud and wrote on clay tablets.

This is why we have lots of Egyptians buildings but not much of their writing and the opposite with the Sumerians."

Rope is one thing that I wonder how to make from scratch if you'd be dropped somewhere in nature. I know it's about weaving plant fibers, but, how can it get so long?

It would be in fact quite amusing if the technology the Neolithians were actually most proud of had nothing to do with stone, just didn’t last. Better fabrics? Waterproof clothing? Elaborate wooden tools made using “dumb” stone ones?

The rope-making video clip is very cool. Sounds plausible.

If you've never watched Clickspring's Youtube videos you're in for a treat.

He has a long-running series where he works to make a new Antikythera mechanism using ancient (bronze age) technologies. He's a master machinist, so he has fabulous insight into workholding, precision, etc. https://www.youtube.com/show/VLPLZioPDnFPNsHnyxfygxA0to4RXv4...

His skeleton clock build is one of my favorite pieces of internet content ever, up there with Bartoz's gorgeous webpages: https://ciechanow.ski/cameras-and-lenses/

Let me guess, it's the boring stuff.
