Theories and interpretations

In the early 20th century, following the work of Walter Baldwin Spencer and Francis James Gillen, scholars such as Salomon Reinach, Henri Breuil and Count Bégouën interpreted the paintings as 'utilitarian' hunting magic to increase the abundance of prey. Jacob Bronowski states, "I think that the power that we see expressed here for the first time is the power of anticipation: the forward-looking imagination. In these paintings the hunter was made familiar with dangers which he knew he had to face but to which he had not yet come."

Another theory, developed by David Lewis-Williams and broadly based on ethnographic studies of contemporary hunter-gatherer societies, is that the paintings were made by paleolithic shamans. The shaman would retreat into the darkness of the caves, enter into a trance state, then paint images of their visions, perhaps with some notion of drawing out power from the cave walls themselves.

R. Dale Guthrie, who has studied both highly artistic and lower quality art and figurines, identifies a wide range of skill and age among the artists. He hypothesizes that the main themes in the paintings and other artifacts (powerful beasts, risky hunting scenes and the representation of women in the Venus figurines) are the work of adolescent males, who constituted a large part of the human population at the time. However, in analyzing hand prints and stencils in French and Spanish caves, Dean Snow of Pennsylvania State University has proposed that a proportion of them, including those around the spotted horses in Pech Merle, were of female hands.

Analysis in 2022, led by Bennet Bacon, an amateur archaeologist, along with a team of professional archeologists and psychologists at the University of Durham, including Paul Pettitt and Robert William Kentridge, suggested that lines and dots (and a commonly seen, if curious, "Y" symbol, which was proposed to mean "to give birth") on upper palaeolithic cave paintings correlated with the mating cycle of animals in a lunar calendar, potentially making them the earliest known evidence of a proto-writing system and explaining one object of many cave paintings.
