This a reference to Africa west of Egypt. It was all "Libu" in Herodotus.
Asia, from the Greek name for the city of Assuwa. This was to reference all of Anatolia/Asia Minor.
Hmm. Didn't 6000-4000BC Northwest Africa was part of Green Sahara? The Sahara drying up was part of the Civilization building in the Nile. Maybe Egypt had some myths about the earliest eras and remember a large, very large area of fertile savanna and forest of pre-Egyptians and pre-Berbers, and Plato got Atlantis from that?
