Must have been heck being an interior designer back then.
FOUR THOUSAND years ago!
It simply staggers the mind.
I had the chance to visit the Chinese National Museum in Taiwan (stuff rescued from China before the Reds took over). It was unbelievable some of the pottery, statues and carvings from 5,000 BC, so 7,000 years ago! (Based on a quick review on the net).
Carved jade, etc. I had no idea people back then could do some of that work.
I was really amazed at those intricate balls of ivory, with all of the numerous layers of spheres within spheres and how old they were. A quick search shows to about 600 A.D.
(obviously not prehistorice - but still amazing.).
And it sounds like it was rediscovered a couple of times.
