Enrico Calzolari in Italy has sent me a number of photos of sites in Italy and Sardinia which I have deciphered and drawn based on his photos and which I reproduce with Enrico's permission.
To our file folder on Italy
I have uploaded
The gif is distorted on some screens because of the size of the picture and you may have to copy it to your graphics program to see it correctly, or, alternatively, look at the .tif, which is shown correctly online.
Grotto N in Combara, Italy, is clearly a carved rock drawing site, where this entrance shows a planisphere of the heavens with the cave entrance forming the ellipse of the Milky Way and the stars outside of that ellipse being around it (so my decipherment).
Historcially, Grotto N was used by "priestesses" of a sort, so that some of the figures seemingly visible toward the back of the cave are not redrawn but only referred to by text.
As can be read at
the first evidence of human settlement in this region is in fact in
caves such as Grotto N.
