The Fayum mummy portraits
These are the portraits of lower Egyptians from the Greco Roman era (Cleopatras era). The burials are mainly of the descendants of the Ptolemaic Egyptian midle class, their local wives and their children.
This isn’t the full range of images, these can be found here, on this page. These are just the images with a better standard of artwork and preservation. Some of the paintings are of a pretty poor artistic standard, and of you look at the full range of them you’ll appreciate why I’ve only posted a few. I have another page, that has just about every good image of mummies and painted funerary portraits of ancient Egyptians here.
There have been quite a few DNA studies on modern Egyptians, and to date, no noticeable amount of DNA from Italy or Greece has been detected, or DNA from anyone other than Arab, Berber and African. The same argument could equally point out that modern Egyptians could actually be darker than the ancient because of the Nubian invasion lead by Piye. Other DNA studies on prehistoric North Africa have revealed mostly Caucasian DNA (Taforalt site), and studies of the teeth, skulls and hair monotonously place Egyptians in the same category as modern North Africans – mainly Caucasian, a bit of African ancestry at the South.
