We propose a wide concept in Megalithic Art that includes the decorations in the interior of the monuments, and also the similar graphics detected in the open air, either on rocks, on menhirs and in various spatial contexts (habitational areas, economic areas, funeral areas). The Megalithic Art so understood appears as very similar in all their regional versions. This model can’t be understood as a settling model of some groups above the other. We understand better an interpretation that advocates by the absorptive capacity and the cultural vivacity of all the implied regions. A capillarity model similar as the one, which is applied to the origin of the European producing peoples. The graphics that we analyse here, while deep expression of the symbolic thought, express strong continuity instead of remarkable breaks. [Copyright &y& Elsevier]
