No one is certain if such a people existed, never mind what they looked like.
“Much stress has been laid by Penka and others on the physical characteristics of the Aryan race, as pointing to Scandinavia as our original home. No one can deny the fact that the people who speak Aryan languages are partly dark and brachycephalic, partly fair and dolichocephalic, and partly mixed. The majority, however, even at the present day, is with the dark and brachycephalic tribes. Nevertheless, we are asked to believe that our earliest forefathers were dolichocephalic, had blue eyes and blond hair, though nothing is said as to how they became brachycephalic, and how their eyes became brown and their hair black. …when will people learn at last that blood has nothing to do with language, and that all we can do as philologists is to classify languages, taking it for granted that they were spoken by somebody, but leaving those somebodies to the tender mercies of the ethnologist?” – Friedrich Max Müller, Biographies of words and the home of the Aryas (1888), pag. 107-108
“I have declared again and again that if I say Aryas, I mean neither blood nor bones, nor hair nor skull; I mean simply those who speak an Aryan language! … I commit myself to no anatomical characteristics. … To me an ethnologist who speaks of Aryan race, Aryan blood, Aryan eyes and hair, is as great a sinner as a linguist who speaks of a dolichocephalic dictionary or a brachycephalic grammar.” – Friedrich Max Müller, Biographies of words and the home of the Aryas (1888), pag. 120
“Ethnologists persist in writing of Aryas…&c., forgetting that these terms have nothing to do with blood, or bones, or hair, or facial angles, but simply and solely with language.” – Friedrich Max Müller, Biographies of words and the home of the Aryas (1888), pag. 245
Needless to say, Friedrich Max Müller’s work was taken out of proportions i.e. in the event that he was supposedly to have been the one who popularized the term.
However, many other Ethnologists, have done so prior to him as he so clearly demonstrated in his book, and it was rather prone to divert Europeans from their true Christian identity, heritage, history and culture.
Aryan (which in essence only means “noble”), is these days commonly used for the Adamic Race (Europeans) and yes I am as guilty as anyone who let it slip in, I might also add, it means to be of a characteristic of pure noble race (Adamic, unmongrelized) and it was not an uncommon usage for the National Socialists!
