“Arthurian myth” is a frequently used term. But what is a ‘myth’? The current discussion of the term in the field of German studies is here opened up to interdisciplinary consideration. Focusing on Arthurian literature, the volume considers which interpretation of ‘myth’ is appropriate to which phenomena. Both content-related and structural definitions of myth are examined, with particular scrutiny of the mythic substrate in Arthurian romances and the various individual approaches to mythical narrative forms. It becomes clear that no definition of ‘myth’ is possible beyond one pertaining to the individual text.
