115. These are the extremities in Asia and in Libya; but as to the extremities of Europe towards the West, I am not able to speak with certainty: for neither do I accept the tale that there is a river called in Barbarian tongue Eridanos, flowing into the sea which lies towards the North Wind, whence it is said that amber comes; nor do I know of the real existence of “Tin Islands” 506 from which tin 507 comes to us: for first the name Eridanos itself declares that it is Hellenic and that it does not belong to a Barbarian speech, but was invented by some poet; and secondly I am not able to hear from anyone who has been an eyewitness, though I took pains to discover this, that there is a sea on the other side of Europe. However that may be, tin and amber certainly come to us from the extremity of Europe. 116.
