These then are the most distant lands in Asia and Libya . But concerning those in Europe that are the farthest away towards evening, I cannot speak with assurance; for I do not believe that there is a river called by foreigners Eridanus issuing into the northern sea, where our amber is said to come from, nor do I have any knowledge of Tin Islands, where our tin is brought from. The very name Eridanus betrays itself as not a foreign but a Greek name, invented by some poet; nor for all my diligence have I been able to learn from one who has seen it that there is a sea beyond Europe . All we know is that our tin and amber come from the most distant parts.
