Today when I was visiting the marketplace for some new pots, I came across a merchant selling these odd, a bit fabric-like white sheets. He told me that the Egyptians make these from reeds to write on them.
Personally, I don’t see a need for such a material. Just use a clay tablet like a normal person!
Clay was good enough for my great-grandfather when he was putting his signet ring on a ball to identify the amphora as coming from his market stall and it’s good enough for me to read the Epic of Gilgamesh on. I just don’t get these Egyptians.
