"Contemporary methodologies, linguistic or archaeological, for determining the spoken language of a remote archaeological culture are virtually nonexistent. Simplified notions of the congruence between an archaeological culture, an ethnic group, and a linguistic affiliation millennia before the existence of texts is mere speculation, often with a political agenda. Archaeology has a long way to go before its methodology allows one to establish which cultural markers, pottery, architecture, burials, etc., are the most reliable for designating ethnic identity."
