Koning Arthur met ridder en Keizer Karel de Grote met priester

King Arthur, a legendary British king who appears in a cycle of medieval romances (known as the Matter of Britain) as the sovereign of a knightly fellowship of the Round Table. It is not certain how these legends originated or whether the figure of Arthur was based on a historical person. The legend possibly originated either in Wales or in those parts of northern Britain inhabited by Brythonic-speaking Celts.
