The Titurel (written around 1220), an added counterpart to Wolfram von Eschenbach's Parzival, can be described as one of the most enigmatic works in the history of German literature. Its highly complex form, peculiar and dark language, and imagery, as well as its fragmentary nature, make the epic one of the most fascinating linguistic creations of the Middle Ages. This bilingual new edition makes the work accessible to a broader audience for the first time. The study edition includes the original text, a critical apparatus, and a modern translation. The study commentary explains difficult passages and introduces the research discussion. A concise preface by the editors and a selected bibliography complement the edition.
