"But even if anthropological data were lacking, the numerous concordant testimonies of ancient texts would be more than sufficient to demonstrate that the upper layer of the population presented the Nordic type. Everywhere, whether common or rare in the population, this type is associated with social status, character and moral value. ... The Nordic type of Indo-European man is not a hypothesis: it is a fact of tradition. Now the decisive advantage of this type of testimony is that it is indisputable: we cannot imagine that the poets would have sung about tall, light-skinned, blond, blue-eyed men if their sponsors had been short, dark, if they had had dark skin and black eyes."
