LOWER AEGYPT
The Ancient Lower AEgypt is Mauritania.
The Eye of Ghorus (ghorus means squint) and called the Eye of Ouadane (Odan) by locals for 3000 years is the Eye of Sahara.
The Eye of Horus was the Kingdom Crest of Mauritania in 3200 BCE based on the actual 3200 BCE Geography Maps of Ancient Mauritania.
Much of Myth is truly Human History sometimes personified, sometimes fictitious, but the "setting " of the underworld is a place where much history truly occurred including the Trogon War the Exodus and the Ragn Bos Auroch resulting in Narmer's Forces retreating to Upper AEgypt in 3200 BCE - 3100 BCE also called the Boser Blick War, The War Against the Evil Eye.
