Hidden or well visible, secret or really known by everybody, in two words public or private: it’s in
this continuous dichotomy that we can describe the rock art tradition of Valcamonica. At least modern
people, as we are, can see and visit (almost) always the rock art sites discovered up today. Was it
possible also in the ancient times? Could everybody visit a rock art site or was the access to
it normed by rules? Why are some panels well visible (because engraved on vertical surfaces), while other
are practically invisible unless we don’t walk over them? Our paper tries to get a key-clue for the interpretation
of these problem
