One can perceive a hierarchy of prestige and a legitimation strategy in the citation practices of those who write on Indo-European myth, religion, and civilization. Those who publish in the most scurrilous sources fail to provide footnotes at all, or do so in quite haphazard fashion . Those whose writings appear in Nouvelle Ecole and Mankind Quarterly, however, regularly invoke articles from the more reputable Etudes indo-europeennes and JIES to establish their scholarly bona fides. In the latter publications and the very best books, authors tend to base themselves on the writings of Georges Dumezil as the firm rock on which all can rest, secure against challenge.

What differentiates him from others of like opinion is the intricate scholarly code he developed, through which he made the arcane data of Indo-European mythology serve as t11e vehicles for his views, and through which his work came to command t11e attention of scholars everywhere. the body of work he produced is so challenging, so dense, and so influential, it deserves continued attention but attention of a critical variety. 137

Other authors have challenged the Stammbaum model on other grounds, observing that even if the historically attested Indo-European languages did descend from a single proto-language, the existence of this ancestral language by no means implies the existence of a single, ethnically homogeneous people who spoke it. Thus Franco Crevatin suggested that Swahili—an artificial lingua franca, spoken across vast portions of Africa as an instrument to facilitate long distance trade—may be a better analogue than Latin for theorizing Proto-Indo-European. His desire, like Trubetzkoy's, seems to be to imagine a more irenic, more diverse past as a means to guard against scholarly narratives that encode racism and bellicosity. In Crevatin's view there was a Proto-Indo-European language and there were people who spoke it for certain finite purposes, but no community of Proto-Indo-Europeans. Similar is Stefan Zimmer's position, intended as a rebuke of racist theories, hypothesizing a protolanguage spoken not be an ethnically pristine Urvolk but by a shifting, nomadic colluvies gentium, a "filthy confluence of peoples," (Lincoln 1999, pp. 212-213).
