“ a brief history of artCave paintings. Clay then bronze statues. Then for about 1,400 years, people painted nothing except bold but rudimentary pictures of either the Virgin Mary and Child or the Crucifixion. Some bright spark realised that things in the distance looked smaller and the pictures of the Virgin Mary and the Crucifixion improved hugely. Suddenly everyone was good at hands and facial expression and now the statues were in marble. Fat cherubs started appearing, while elsewhere there was a craze for domestic interiors and women standing by windows doing needlework. Dead pheasants and bunches of grapes and lots of detail. Cherubs disappeared and instead there were fanciful, idealised landscapes, then portraits of aristocrats on horseback, then huge canvasses of battles and shipwrecks. Then it was back to women lying on sofas or getting out of the bath, murkier this time, less detailed then a great many wine bottles and apples, then ballet dancers. Paintings developed a certain splodginess - critical term - so that they barely resembled what they were meant to be. Someone signed a urinal, and it all went mad. Neat squares of primary colour were followed by great blocks of emulsion, then soup cans, then someone picked up a video camera, someone else poured concrete, and the whole thing became hopelessly fractured into a kind of confusing, anything-goes free for all. ”
