I’ve recently listened to Bob Brier’s history of ancient Egypt where he discusses the early kings and the Narmer Palette and something struck me, the artwork on the palette shows a clearly defined Egyptian culture that appears to be really well formed and that there must have been a gradual lead up to that rather than a light switch that went from nomadic farmers to a fully developed civilisation. What if any evidence is there of this transition and can anyone point me towards some more reading material? Thank you!
