Thanks for that link. Tracey's stuff embodies everything that has gone wrong with society, it seems to me. I can't bear to look at it. On another thread I rambled on about buying metal detectors' finds and, amongst them, is a Roman child's toy, a hollow cast pig, two two and a half inches long. (I'm going to list it on eBay at the weekend). That too captures a pig perfectly - in a way that doesn't seem possible nowadays. I have my own Chauvet cave - it's called the Bold Venture and I'm the only person to have visited. If Berger's staement is extended then it is is the making of art that defines us as human.
