Since the very first images were made by dipping hands in natural pigment and pressing them on cave walls in Lascaux and Altamira artists have been getting their hands dirty to make their mark. These simple images have to be some of the most economical, powerful and evocative symbols known to us. I believe it helpful to revisit visual images of this nature, to regain perspective and seek solace in them - especially at times when contemporary questions abound such as those being asked at this colloquium.
