It remains unknown how a population large enough to construct, augment, and maintain such a substantial complex was mobilized and compensated or fed in the conditions of pre-sedentary society. Scholars have been unable to interpret the pictograms, and do not know what meaning the animal reliefs had for visitors to the site. The variety of fauna depicted – from lions and boars to birds and insects – makes any single explanation problematic. As there is little or no evidence of habitation, and many of the animals pictured are predators, the stones may have been intended to stave off evils through some form of magic representation. Alternatively, they could have served as totems.
