Engraved slabs from the interior of passage graves. The first one comes
from the dolmen of the Pierres Plates, Gulf of Morbihan (Brittany, France);
the second from Gavrinis island (Brittany, France). The engravings show
a series of wavy lines and spirals the meaning of which is not easy
to detect. Marija Gimbutas, in her wide research on Neolithic religions,
has suggested that images like these recall the idea of flux, radiation,
thus referring to the generative force of the feminine (Gimbutas 2005).
Their presence on the wall of megalithic tombs betakes the conception
of a continuous cycle intertwining life and death together and attributing
to the dead and ancestors a central role in the regeneration of vital
force.
