In the list of Ethiopian Kings given by Haile Selassie I, we find the name of King Etyopis, buried under the obelisks of Axum, which is the same of Ethiopia as country. It is dated 1800 years before the birth of Christ.
King Etyopis came about 1000 years before the birth of the Greek archaic literature. Why Ethiopia should be a Greek name, if Greek civilization never ruled Ethiopia and it is clearly younger ?
This is just an absurd dogma of the euro-centric colonial academic system, trying to inculcate some form of western historical or cultural domination. Indeed, the rational historical path should be the inverse, so the Greek have taken this word from Africa and built their notions around it.
In fact, in ancient Greek, the word “topos” τόπος means “place”: as Homer said, Ethiopia was the perfect place where the gods loved to stay, and then the Greek people adopted the name of Ethiopia as archetypical idea of place.
