"Aryan people first emerge from the gloom of prehistory on the northern borders of the Fertile Crescent of the Ancient East... So it is clear enough that the dynasts installed on the Upper Euphra­ tes by 1400 B.C. were Aryans, closely akin to those we meet in the Indus Valley and later in Media and Persia... (the first Aryans were racially Nordics and) the Nordic's superiority in physique fitted them to be vehicles of a superior language. (Childe 1926: 16,19,212)"
