'Titurel', a later offshoot of Wolfram von Eschenbach's 'Parzival', can be seen as one of the most enigmatic works in the history of German literature. With its highly complex form, the darkness of its language and imagery, and its fragmentary character, it is one of the most fascinating linguistic creations of the Middle Ages. This new edition, with its wealth of ancillary material, now makes the work accessible to a wider readership for the first time.
