He was poor and with a family, and could neither read nor write; but knew French and was of noble birth, which enabled him to frequent the court of Hermann of Thuringia. His chief works were three epic poems: "Parzival" (about 1210), the greatest of German court epics; "Titurel" (about 1210?), left unfinished; "Willehalm" (begun before 1216), left unfinished; both afterward completed by other hands. He wrote also lyrics, among which were four "Day Songs."
He died about 1220.
