Analysis of information sources in references of the Wikipedia article "Aethiopia" in English language version.
The country above Elephantine now begins to be inhabited by Ethiopians: half the people of the island are Ethiopians, and half Egyptians. Near the island is a great lake, on whose shores live nomadic Ethiopians. After crossing this, you come to the stream of the Nile, which empties into this lake.
The inhabitants of the south resemble the Ethiopians in colour, but their countenances and hair are like those of other people. Their hair does not curl, on account of the humidity of the atmosphere. The inhabitants of the north resemble the Egyptians.
