Above these parts is the district which produces silphium, then follows the uninhabited tract, and the country of the Garamantes. The district which produces silphium is narrow, long, and dry, extending in an easterly direction about 1000 stadia, but in breadth 300 stadia, or rather more, at least as far as has been ascertained. For we may conjecture that all countries which lie on the same parallel (of latitude) have the same climate, and produce the same plants; but since many deserts intervene, we cannot know every place. In like manner, we have no information respecting the country beyond (the temple of) Ammon, nor of the oases, as far as Ethiopia, nor can we state distinctly what are the boundaries of Ethiopia, nor of Africa, nor even of the country close upon Egypt, still less of the parts bordering on the ocean.

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.
