The painted cave systems of the Upper Palaeolithic, Lascaux and Chauvet in France, Altamira in Spain among the best known, depict animals almost exclusively, aurochs, horses, bison and deer rendered with a technical confidence that surprised early researchers unused to attributing such skill to people this far back in prehistory. Human figures appear only rarely and are often stylized, incomplete or combined with animal features, in sharp contrast to the careful naturalism given to the animals themselves, an asymmetry scholars have long taken as a clue to what the images were for, even though no text survives anywhere to confirm any specific reading.
The dominant scholarly interpretation reads the caves as sites of ritual rather than simple decoration, pointing to their frequent placement deep in cave systems far from any evidence of ordinary habitation, to superimposed layers of paintings added over long stretches of time at the same locations, and to occasional partial human or human animal figures read by some researchers as evidence of shamanistic trance practice, a figure transformed or transforming rather than simply depicted. This shamanistic reading remains genuinely contested rather than settled fact: it explains some features of the art well and others only speculatively, and rival interpretations, hunting magic, seasonal calendars, teaching sites, group identity markers, each account for part of the evidence without any one commanding full consensus. What is not contested is that image making of this sophistication, this early, already required people to hold and transmit shared symbolic meaning across generations, whatever that meaning specifically was.
