Four thousand years ago, in Western Europe, men with crude stone tools carved intricate patterns over the great stone tombs of their dead. Tonight in Chronicle two artists, Patrick Carey and Peter Rawstorne, see if it is possible with the eye of imagination to get behind the abstract forms of this art to the mind of the Stone Age men who created it. Patrick Carey's film, Mists of Time, explores the world of magic of the ancient artists. Peter Rawstorne's exhibition of tracings reflects the strange designs and patterns they used to create this world.
