9. _Whether we are to believe in the Antipodes._
But as to the fable that there are Antipodes, that is to say, men on the opposite side of the earth, where the sun rises when it sets to us, men who walk with their feet opposite ours, that is on no ground credible. And, indeed, it is not affirmed that this has been learned by historical knowledge, but by scientific conjecture, on the ground that the earth is suspended within the concavity of the sky, and that it has as much room on the one side of it as on the other: hence they say that the part which is beneath must also be inhabited. But they do not remark that, although it be supposed or scientifically demonstrated that the world is of a round and spherical form, yet it does not follow that the other side of the earth is bare of water; nor even, though it be bare, does it immediately follow that it is peopled. For Scripture, which proves the truth of its historical statements by the accomplishment of its prophecies, gives no false information; and it is too absurd to say, that some men might have taken ship and traversed the whole wide ocean, and crossed from this side of the world to the other, and that thus even the inhabitants of that distant region are descended from that one first man. Wherefore let us seek if we can find the city of God that sojourns on earth among those human races who are catalogued as having been divided into seventy-two nations and as many languages. For it continued down to the deluge and the ark, and is proved to have existed still among the sons of Noah by their blessings, and chiefly in the eldest son Shem; for Japheth received this blessing, that he should dwell in the tents of Shem.
10. _Of the genealogy of Shem, in whose line the city of God is preserved till the time of Abraham._
It is necessary, therefore, to preserve the series of generations descending from Shem, for the sake of exhibiting the city of God after the flood; as before the flood it was exhibited in the series of generations descending from Seth. And therefore does divine Scripture, after exhibiting the earthly city as Babylon or "Confusion," revert to the patriarch Shem, and recapitulate the generations from him to Abraham, specifying besides, the year in which each father begat the son that belonged to this line, and how long he lived. And unquestionably it is this which fulfils the promise I made, that it should appear why it is said of the sons of Heber, "The name of the one was Peleg, for in his days the earth was divided."[248] For what can we understand by the division of the earth, if not the diversity of languages? And, therefore, omitting the other sons of Shem, who are not concerned in this matter, Scripture gives the genealogy of those by whom the line runs on to Abraham, as before the flood those are given who carried on the line to Noah from Seth. Accordingly this series of generations begins thus: "These are the generations of Shem: Shem was an hundred years old, and begat Arphaxad two years after the flood. And Shem lived after he begat Arphaxad five hundred years, and begat sons and daughters." In like manner it registers the rest, naming the year of his life in which each begat the son who belonged to that line which extends to Abraham. It specifies, too, how many years he lived thereafter, begetting sons and daughters, that we may not childishly suppose that the men named were the only men, but may understand how the population increased, and how regions and kingdoms so vast could be populated by the descendants of Shem; especially the kingdom of Assyria, from which Ninus subdued the surrounding nations, reigning with brilliant prosperity, and bequeathing to his descendants a vast but thoroughly consolidated empire, which held together for many centuries.
