It must also be admitted that the original characteristics of different nations are changing day by day, and are therefore more difficult to grasp.  As races blend and nations intermingle, those national differences which formerly struck the observer at first sight gradually disappear.  Before our time every nation remained more or less cut off from the rest; the means of communication were fewer; there was less travelling, less of mutual or conflicting interests, less political and civil intercourse between nation and nation; those intricate schemes of royalty, miscalled diplomacy, were less frequent; there were no permanent ambassadors resident at foreign courts; long voyages were rare, there was little foreign trade, and what little there was, was either the work of princes, who employed foreigners, or of people of no account who had no influence on others and did nothing to bring the nations together.  The relations between Europe and Asia in the present century are a hundredfold more numerous than those between Gaul and Spain in the past; Europe alone was less accessible than the whole world is now.

Moreover, the peoples of antiquity usually considered themselves as the original inhabitants of their country; they had dwelt there so long that all record was lost of the far-off times when their ancestors settled there; they had been there so long that the place had made a lasting impression on them; but in modern Europe the invasions of the barbarians, following upon the Roman conquests, have caused an extraordinary confusion.  The Frenchmen of to-day are no longer the big fair men of old; the Greeks are no longer beautiful enough to serve as a sculptor’s model; the very face of the Romans has changed as well as their character; the Persians, originally from Tartary, are daily losing their native ugliness through the intermixture of Circassian blood.  Europeans are no longer Gauls, Germans, Iberians, Allobroges; they are all Scythians, more or less degenerate in countenance, and still more so in conduct.

This is why the ancient distinctions of race, the effect of soil and climate, made a greater difference between nation and nation in respect of temperament, looks, manners, and character than can be distinguished in our own time, when the fickleness of Europe leaves no time for natural causes to work, when the forests are cut down and the marshes drained, when the earth is more generally, though less thoroughly, tilled, so that the same differences between country and country can no longer be detected even in purely physical features.

If they considered these facts perhaps people would not be in such a hurry to ridicule Herodotus, Ctesias, Pliny for having described the inhabitants of different countries each with its own peculiarities and with striking differences which we no longer see.  To recognise such types of face we should need to see the men themselves; no change must have passed over them, if they are to remain the same.  If we could behold all the people who have ever lived, who can doubt that we should find greater variations between one century and another, than are now found between nation and nation.
