As for the land of which my history has begun to speak, no one exactly knows what lies north of it; for I can find out from no one who claims to know as an eyewitness. For even Aristeas, whom I recently mentioned—even he did not claim to have gone beyond the Issedones, even though a poet; but he spoke by hearsay of what lay north, saying that the Issedones had told him. But all that we have been able to learn for certain by report of the farthest lands shall be told.
