I'd love to see this 3D documentary by Werner Herzong. Coincidentally, I've been spending a bit of time over the last few weeks listening to descriptions of the caves in Lascaux in Southern France where Picasso emerged and said 'we've learned nothing' after seeing the intense visionary drawings which in this instance also adorn the caves at Chauvet Pont d'Arc. However both locations (and others) liberally portray therianthropes for no explicable rational reason.
Anybody else learned of the similarities between these caves and the features of cathedrals such as Chartres?
