Unveiling the Evolution of Ancient Art: From Hidden 3D Animals to Changing Pigments

Researchers have used stereoscopic photography, a centuries-old technique, to identify hidden animal figures on the walls of a cave in Spain. The method involves taking pairs of high-resolution photographs that can be viewed together to create a 3D image. Through this technique, archaeologists discovered previously unseen depictions of horses and an extinct cattle species. The photographs provide a more accurate representation of how the art would have been perceived by the cave's creators, offering new insights into the creative process of Paleolithic cave artists.
