" Here we come to a semantic difficulty. Other peoples who were of considerable civilization had been referred to as barbarians for more than a thousand years. Others had been called by the names of the wolves. When the wolves themselves came, there was no other name to give them. The Goths, who were kingdom-founding Christians, had been called barbarians. The Gauls of ancient lineage had been so called, and the talented Vandals.
Even the Huns had been called barbarians. This is a thing beyond all comprehension, and yet it is not safe to contradict the idea even today. The Huns were a race of over-civilized kings traveling with their Courts. In the ordering of military affairs and in overall organization they had no superiors in the world. They were skilled diplomats, filled with urbanity and understanding. All who came into contact with them, Persians, Armenians, Greeks, Romans, were impressed by the Huns' fairness in dealing—considering that they were armed invaders; by their restraint and adaptability; by their judgment of affairs; by their easy luxury. They brought a new elegance to the Empire peoples; and they had assimilated a half dozen cultures, including that of China. But the Huns were not barbarians; no more were any of the other violent visitors to the Empire heretofore. "
