Old Norse, Old Nordic, or Old Scandinavian is a stage of development of North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia and the consolidation of Scandinavian kingdoms from about the 8th to the 15th centuries.
The Rök runestone in Östergötland, Sweden, is the longest surviving source of early Old East Norse. It is inscribed on both sides.
