Through the many literary works that have effectively attempted to create the figure Arthur, a fairly solid composite emerges. The events that shape the Arthurian legend are a mixture of the historic chronology of Europe and the several ficticious stories and occurences that took place only in the pages of literature. Though there have been scholars who have theorized that Arthur is a shadow or a tale mirroring great Celtic or Norse kings who actually lived and of whom we have fragmented histories, the Arthur known to the world is a character of literature more than history. The oldest known Arthurian work is the poem Culhouch and Owlen.Through such great authors as Geoffrey of Monmouth, Chretien, Malory, Tennyson, Wagner, and White, Arthur has become an immortal literary phenomenon that continues to be popular today.
