This article highlights the “linguistic areas” for the vigesimal counting system in the Palearctic region. These areas can be associated with the existing language families to a considerable degree. The vigesimality appears as an archaism that it is interesting, particularly with regard to the Neolithization process whose spatiotemporal dynamics in Europe are well known. In a long-term history of counting and number construction, the attempt to understand this phenomenon should be given an anthropological perspective and an interdisciplinary approach that includes both linguistics and cognitive sciences.
