Cela rejoint ce que j'avais écrit sur le topic concernant les campaniformes.
Un archéologiste, Kristian Kristiansen, a écrit récemment dans le dernier numéro des dossiers d'archéologie sur les Indo-Européens, ceci:
Citer :
A partir du milieu du IIIè millénaire, la rencontre entre les cultures des tombes individuelles/culture de la céramique cordée au nord, et les cultures Campaniformes au sud, entraina l'apparition des langues proto-celtiques qui s'étendirent de la péninsule ibérique aux Iles Britanniques et devinrent ainsi les principales langues de la côte atlantique. Elles ne diffusèrent en Europe centrale qu'au début de l'âge du fer.
Ainsi le campaniforme pourrait être à l'origine de la celtisation de l'Europe occidentale au 3ème millénaire avant JC.

Citer :
Beyond the Aegean, some of the earliest written records of Europe come from the south-west, what is now southern Portugal and south-west Spain. Herodotus, the 'Father of History', locates the Keltoi or 'Celts' in this region, as neighbours of the Kunetes of the Algarve. He calls the latter the 'westernmost people of Europe'. However, modern scholars have been disinclined - until recently - to consider the possibility that the south-western inscriptions and other early linguistic evidence from the kingdom of Tartessos were Celtic. This book shows how much of this material closely resembles the attested Celtic languages: Celtiberian (spoken in east-central Spain) and Gaulish, as well as the longer surviving languages of Ireland, Britain, and Brittany. In many cases, the 85 Tartessian inscriptions of the period c.750-c.450 BC can now be read as complete statements written in an Ancient Celtic language.
