Runestone

Möjbro Runestone, ca. 5th century.
Wikipedia - "A runestone is typically a raised stone with a runic inscription, but the term can also be applied to inscriptions on boulders and on bedrock. The tradition began in the 4th century, and it lasted into the 12th century, but most of the runestones date from the late Viking Age. Most runestones are located in Scandinavia, but there are also scattered runestones in locations that were visited by Norsemen during the Viking Age. Runestones are often memorials to deceased men. Runestones were usually brightly colored when erected, though this is no longer evident as the color has worn off."
