Recent research in the DNA of prehistoric horses has resulted in a new interpretation of the well-known panel of the Spotted horses
of Pech Merle. The conclusion that has been popularized by this research is that the artists accurately depicted the animals as they saw them in their environment. It has long been evident that some artists of the European Ice Age caves were able to realize graphic memesis to a remarkable degree. This new study of the genome of ancient horses appears to confirm the artist’s intention of creating the actual appearance of dappled horses. I will question this conclusion as well as the relevance of this study to the art by examining the Spotted horses
in the context of the entire panel and the panel in the context of the whole cave. To further enlarge our view, I will consider the use of similar dots and dappling in the rock art of other paleolithic people. The visual effect of dots will be seen in terms of their psychological impact. Discoveries by neuroscientists regarding the effect of such stimuli on human cognition will be mentioned. I will conclude with another possible interpretation of the meaning of the Spotted horses
of Pech Merle.
