The circulation of large polished axe blades during the second half of the 5th millennium B.C. is a major phenomenon of the Western European Neolithic. Three recent discoveries of axe blades made of Alpine rocks are assimilated to this issue. The two blades from Vendeuil, discovered planted in the ground with the cutting edge facing upwards, exemplify the status of these oversized tools, which the social value-system has transported into the domains of ritual and the sacred ; their demonstrated place of origin is from Monviso (Piedmont, Italy), from rock quarried at 2400 metres. We can propose a provenance from Monviso or from Voltri for the two other axe blades, although this cannot yet be demonstrated by the spectroradiometric analyses.
