LONDON, ENGLAND—Archaeologists reexamining artifacts unearthed in a 1970 excavation in London’s Brentford neighborhood have discovered a fourth-century piece of pottery decorated with a Christian symbol. Culture 24 reports that the sherd was unearthed with a number of other artifacts when the line of a Roman road was discovered running between ancient Londinium and the west of Britain. Close examination of the sherd showed it bears a monogram of first two letters of the Greek Khristos (Christ). “Christian symbols from the Roman period are rare, especially from sites within Londinium’s surrounding Hinterland,” says archaeologist Adam Corsini of the Museum of London. “There are only a few examples within our collections relating to London.” To read about another rare Roman artifact unearthed in London, go to “Artifact: Roman Eagle Sculpture.”
