In the tomb of a nobleman (Khnumhotep) who lived in the 12th dynasty, the image of people (looks like farmers) has a symbol above it.
According to this particular web page, the 12th dynasty was around 1800 BC
According to the Hyksos story, Ahmose drove them out drove them out around 1600 BC.
Depending which "expert's" web page you read, the Hyksos were there between 100 and 500 years.
Hmmm, looks like that symbol is above a goat. Could that be the Hyksos ruler?
If they are all rulers, who gets to be their subjects, the livestock?
Any these "Hyksos rulers" look like a bunch of farmers to me.
Wouldn't it be great if some 'expert' actually looked at all the hieroglyphs on that wall to see what the Egyptian authors had to say?
