Comment Re:Writing in clay (Score 1) 40
If you want the epoch of the "Clay Age" I suppose it would be about 2900-3100 BCE, in the Sumerian civilization of Mesopotamia. They started writing in cuneiform script on wet clay tablets that dried and became a hard record.
Interesting. Mythologized an eon later, "Because the messenger's mouth was heavy and he couldn't repeat, the Lord of Kulaba patted some clay and put words on it, like a tablet. Until then, there had been no putting words on clay.
—Enmerkar and the Lord of Aratta (c.1800 BCE)"
Those address the first application of spoken language to writing. Just to confuse matters a bit more, "The first writing can be dated back to the Neolithic era, with clay tablets being used to keep track of livestock and commodities." (per the wiki. I'll have to look more into this, I don't know if I've seen anything about it.) I have read that Egyptian hieroglyphics were originated for accounting. (Allegedly for beer, but I read about this in a "history of beer" article, so YMMV.)
