The latter, particularly, points to a religious or ritual function to these carvings, and indeed to the practice of a form of «shamanism» — that is, an
archaic magical or religious
belief system which sought connections between the visible and spirit worlds, and which ascribes spiritual properties to animals and natural forces.
The rock art, Boyd says, displays an
archaic core: an ancient
belief system that has been widely shared in Mesoamerican mythological traditions.
