1 This is enough of the story told by Etearchus the Ammonian; except he said that the Nasamonians returned, as the men of Cyrene told me, and that the people to whose country they came were all wizards;
2 as to the river that ran past the city, Etearchus guessed it to be the Nile; and reason proves as much. For the Nile flows from Libya, right through the middle of it; and as I guess, reasoning about things unknown from visible signs, it rises proportionally as far away as does the Ister.
3 For the Ister flows from the land of the Celts and the city of Pyrene through the very middle of Europe; now the Celts live beyond the Pillars of Heracles, being neighbors of the Cynesii, who are the westernmost of all the peoples inhabiting Europe.
4 The Ister, then, flows clean across Europe and ends its course in the Euxine sea, at Istria, which is inhabited by Milesian colonists.
