Roman mosaic found in Cotswold field

Paul Ballinger and John Carter didn't find anything with their metal detector recently, but noticed tiles in a plowed field. After some searching, they uncovered a 40-foot (12 meter) diameter mosaic floor dating to 4th century Roman times. (photo)

The mosaic floor, found near Kemble, England, is one of the largest early mosaics yet discovered in the country.
