"Jarrige and Hassan reject the idea that these finds were associated with invaders related to the Hissar III C complex, since "there is nothing in the Gorgan Plain and at Hissar to prove that northern Iran has been a relay station for invading people. The . . . grey ware can very well be explained within its local context" (163-164). Nor are these scholars partial to the northern steppe Andronov alternatives, since: We leave to the linguists the problem of whether Indo-European languages were introduced into the Middle Asian regions from a still unknown part of the Eurasian steppes in the course of the third millennium or if Indo-Iranian languages have been associated with these regions for a much longer period. As far as archaeology is concerned, we do think that it is increasingly necessary for specialists in Indo-lranian studies to pay attention to the . . . interrelated cultural entities of the late third and early second millennium in the regions between Mesopotamia and the Indus. It is a direction of research that is likely to be more fruitful than are traditional attempts to locate remains left by nomads from "the Steppes," attempts that were in fashion when the Indo-Iranian Borderlands were thought to be a cultural vacuum.
