This female aurochs is one of the most accomplished figures in Lascaux. This is due to the abundance and quality of the anatomical details, but also to the rendering of motion, which is rarely found in Prehistoric iconography. The body is contorted and its hindlimbs are flattened against its abdomen. To attenuate the problems of working with a brush on a coarse-grained surface, the red and black pigments that make up the structuring lines for the body, head and limbs were applied using the spray technique. Only the horns and muzzle were applied with a brush. The image of the Falling Cow is indissociable from the red grid sign that appears just in front of it. A number of researchers have compared this geometric figure to a trap, but the Palaeolithic imagination was certainly more complex than it now appears.
