“The truth is that applying words such as ‘worth’ and ‘value’ to art is an abuse of language. They are terms not of art but of a science, that of economics. They describe price in a market in which supply is fixed but demand exorbitant. Nobody does Klimts any more. The picture was expensive because, unless Christie’s was pulling a fast one in a “negotiated” secret deal, there must have been another buyer prepared to pay nearly as much. Getting journalists to hype a work of art to legitimise its market price is playing with words.”
