The Atlantic Ocean was once called the Aethiopian Ocean according to Princeton University's map collections research. And the fact checkers at Africa Check, an online fact verifier, gives the university a thumbs up, on its findings. Works such as the Illiad and the Odyssey, meanwhile, reveal the whole of Africa was called Ethiopia two-thousand years ago.
The term Ethiopian Ocean/Sea fell out of favor during the height of European colonialism in the 18th century.
