But with respect to the Grecians, as no barrier has ever existed between them and any other [Footnote 3] race than the Turks, and these only in the shape of religious scruples, which on one side had the highest political temptation to give way, there was no pledge stronger than individual character, there could be no national or corporate pledge, for the maintenance of this insulation. As therefore, in many recorded cases, the strongest barrier (viz., that against Mahometan alliances) is known to have given way, as in other cases innumerable, but forgotten, it must be presumed to have given way? this inference follows, viz., that if anywhere the Grecian blood remains in purity, the fact will be entirely without evidence; and for us, the result will be the same as if the fact had no existence. Simply as a matter of curiosity, if our own opinion were asked as to the probability, that in any situation, a true-blooded population yet survives at this day, we should answer that, if anywhere, it will be found in the most sterile of the Greek islands. Yet, even there the bare probability of such a result will have been open to many disturbances; and especially if the island happen to be much in the way of navigators, or the harbors happen to be convenient, or if it happen to furnish a good stage in a succession of stages, (according to the ancient usages of Mediterranean seamanship), or if it possessed towns containing accumulations of provisions or other stores, or offered good watering-places; under any of these endowments, an island might be tempting to pirates, or to roving adventurers, or to remote overpeopled parts of Italy, Africa, Asia Minor, &c.; in short, to any vicious city where but one man amongst the poorer classes knew the local invitations to murderous aggressions. Under so many contingencies operative through so many centuries, and revolutions so vast upon nations so multiplied, we believe that even a poor unproductive soil is no absolute pledge for non-molestation to the most obscure of recesses.
