Druids belong to the realm of myth - archaeologists have never been able to prove their existence. But now researchers in England have uncovered the grave of a powerful, ancient healer. Was he a druid?

There's a joke among archaeologists: Two of their kind, in the future, find a present-day public toilet. "We've discovered a holy site!" cries one. "Look, it has two separate entrances," says the other. "This here," he says, pointing to the door with a pictogram of a woman, "was for priests. This is evident by the figure wearing a long garment."

Philip Crummy is an archaeologist who tries not to pass off ancient toilets for holy sites but, lately, the director of the Colchester Archaeological Trust has been pulling a number of artifacts from the ground near the site of an ancient city, Camulodunum, that would tempt any archaeologist to speculate, at least a little. Crummy has stumbled upon a small cemetery about 4.5 kilometers (2.8 miles) southwest of present-day Colchester. The dead were all buried between the years 40 and 60 A.D. For a cemetery that's a short lifespan; but in Britain it's an important period, because in the year 43 A.D. the island became a Roman colony.
