Strabo was a great traveller, and apparently had no professional or other occupation. We may therefore conclude that his father left him a good property. Much of his geographical information is the result of personal observation. In a passage of his 2nd book[8] he thus speaks: “Our descriptions shall consist of what we ourselves have observed in our travels by land and sea, and of what we conceive to be credible in the statements and writings of others; for in a westerly direction we have travelled from Armenia to that part of Tyrrhenia which is over against Sardinia; and southward, from the Euxine to the frontiers of Ethiopia. Of all the writers on geography, not one can be mentioned who has travelled over a wider extent of the countries described than we have. Some may have gone farther to the west, but then they have never been so far east as we have; again, others may have been farther east, but not so far west; and the same with respect to north and south. However, in the main, both we and they have availed ourselves of the reports of others, from which to describe the form, size, and other peculiarities of the country.” He mentions having been in Egypt, the island Gyarus, Populonium near Elba, Comana in Cappadocia, Ephesus, Mylasa, Nysa, and Hierapolis in Phrygia. He visited Corinth, Argos, Athens, and Megara; but, on the whole, he does not appear to have seen more of Greece than in passing through it on his way to Brundusium, while proceeding to Rome. Populonium and Luna in Italy were the limit of his travels northwards. It is probable he obtained his information as to Spain, France, Britain, and Germany, while staying at Rome. The first systematic writer on geography was Eratosthenes, who died at the age of 80, about B. C. 196. His work consisted of three books.
