Pausanias Description of Greece 1.33.5

[5] There are other Aethiopians who are neighbours of the Mauri and extend as far as the Nasamones. For the Nasamones, whom Herodotus calls the Atlantes, and those who profess to know the measurements of the earth name the Lixitae, are the Libyans who live the farthest close to Mount Atlas, and they do not till the ground at all, but live on wild vines. But neither these Aethiopians nor yet the Nasamones have any river. For the water near Atlas, which provides a beginning to three streams, does not make any of the streams a river, as the sand swallows it all up at once. So the Aethiopians dwell near no river Ocean.
