There was a Roman burial unearthed where there was almost an entire skeleton. The occupant would have been 6’ 7” or 6’ 8” in life. Founder Petrie an early Egyptian archeologist (I think I remember this right!) found a leg bone attributed to a Pharaoh of the 2nd Dynasty and his height is estimate to be 8’. I had two friends in high school who could have worn that shoe.
All this shows that genetic disorders gigantism/acromegaly were human conditions not unknown to the ancient world. Considering how closely the Pharaohs interbred its a wonder they maintained 2 arms, 2 legs & 1 head!
“Founder Petrie an early Egyptian archeologist ....”
I believe you mean Flinders Petrie.
