Ancient Aethiopia, (Greek: Αἰθιοπία, romanized: Aithiopía) first appears as a geographical term in classical documents in reference to the skin color of the inhabitants of the upper Nile in northern Sudan along with areas south of the Sahara and certain parts of Asia. Its earliest mention is in the works of Homer: twice in the Iliad, and three times in the Odyssey. The Greek historian Herodotus uses the appellation to refer to regions south of Egypt when describing "Aethiopians," most commonly Nubia. Likewise, the Hebrew term Cushi is derived from Kushite. Despite this, the Byzantine Greeks also referred to the Aksumites as Ethiopians and Negus Ezana, conqueror of Meroë took on the title of "king of Ethiopia" prior to the rise of the medieval Ethiopian Empire. The ancient Libyans (North African Berbers) were also called White Aethiopians by contemporary Greek sources. By the modern period the term Aethiopian Sea was used to refer to the southern Atlantic ocean, particularly the area adjacent to West Africa.
Inhabitants of Herodotus' India were sometimes named Ethiopians for their dark skin by the Greeks and Romans. In book 3 (3.89-97) however, Herodotus himself distinguishes the people of India. "All the tribes which I have mentioned live together like the brute beasts: they have also all the same tint of skin, which approaches that of the Ethiopians."
