 Recent radiocarbon studies, both on materials recovered from archaeological deposits in the rockshelters and on materials in the paintings themselves, have suggested that the Great Murals may have a time range extending as far back as 7,500 years ago.No consensus exists about the motivations that led to the painting of the Great Murals.Among the contexts suggested for their production have been hunting magic, warfare, shamans' traces, weather control, and ancestor veneration.
