The Guardian view on metal detecting: hobbyists as well as experts can play a part in unearthing the past | Editorial

Detectorists and archaeologists sometimes clash, but the recent find of two Roman swords was the thrilling result of collaboration

The discovery of two swords at a dig in Gloucestershire has fuelled speculation that a Roman villa may once have stood there, at a period in the second or third century AD when Saxons were making inroads in the region. Experts think that the blades may even have been deliberately hidden - but not deep enough to concealthem from a novice metal detectorist, GlennManning. Next month, the public will get a chance to see the weapons when they go on display at the Corinium museum in Cirencester, to which they havebeen given.

The items join a growing list of striking finds by hobbyists. These include a gold nugget found in the Shropshire Hills by Richard Brock, who located it with the help of an old machine that was only half working". Another newcomer dug up a gold necklace bearing the initials of Henry VIII and Katherine of Aragon, which is now in the British Museum.
