Looks pretty human to me. Not quite Michelangelo, but not 3rd grade either. I don't expect their drawings to last too well after 4,000 years.
I have long accepted that the ancients were as intelligent as modern man.
What I cannot explain is their “art”. Children’s drawings are often more inspired than what, it seems, the ancients produced. It seems that you have to get to Greece to see human forms that actually look human. I can’t explain it.
Egyptian “art” is not “art.” It’s writing.
It’s not meant to be inspired anymore than the typeface of your local paper. It’s meant to be “readable.”
Just something to keep in mind.
