A place called Glozel in France is the setting for what must be either the most extraordinary discovery in the history of archaeology - or a monstrous fraud. Weird pots and phallic idols and magic writings are the bones of contention between archaeologists who have declared for more than 40 years that Glozel is a modern fake and some physicists who have been saying for the past four years that everything they have tested with their 'glow-curve' dating method is at least 2,000 years old. Chronicle has been following the case since 1974 and reports tonight with a round-up of all the latest evidence on the unsolved mystery that still surrounds Glozel.
