Tertullian

“ Granted, then, that the Phrygians were the earliest race, it does not follow that the Christians are the third. For how many other nations come regularly after the Phrygians? Take care, however, lest those whom you call the third race should obtain the first rank, since there is no nation indeed which is not Christian. Whatever nation, therefore, was the first, is nevertheless Christian now. [9] It is ridiculous folly which makes you say we are the latest race, and then specifically call us the third. ”

“ We are indeed said to be the “third race” of men. What, a dog-faced race? [2] Or broadly shadow-footed? [3] Or some subterranean [4] Antipodes? If you attach any meaning to these names, pray tell us what are the first and the second race, that so we may know something of this “third.” Psammetichus thought that he had hit upon the ingenious discovery of the primeval man. ”
