Book 17
3.24
Such, then, is the disposition of the parts of the world which we inhabit.τῆς καθ’ ἡμᾶς οἰκουμένης, Groskurd translates as inhabited to our time; but Strabo refers to the then known world, having before, b. i. c. iv. § 6, in a remarkable manner conjectured the existence of other habitable worlds (such as America) in the latitude of Athens. We call that (part of the temperate zone) the habitable earth (οἰκουμένην) in which we dwell, and with which we are acquainted; but it is possible, that in the same temperate zone there may be two or even more habitable earths, especially near the circle of latitude drawn through Athens and the Atlantic Ocean. The latitudes of Athens and Washington do not differ by one degree. But since the Romans have surpassed (in power) all former rulers of whom we have any record, and possess the choicest and best known parts of it, it will be suitable to our subject briefly to refer to their Empire.

It has been already statedB. vi. c. iv. § 2. how this people, beginning from the single city of Rome, obtained possession of the whole of Italy, by warfare and prudent administration; and how, afterwards, following the same wise course, they added the countries all around it to their dominion.

Of the three continents, they possess nearly the whole of Europe, with the exception only of the parts beyond the Danube, (to the north,) and the tracts on the verge of the ocean, comprehended between the Rhine and the Tanaïs (Don).
