Written in the late-twelfth century, the Old French Romance of Tristran by Beroul is one of the earliest surviving versions of the story of Tristran and Iseut. Preserved in only one manuscript, the poem records the tragic tale that became one of the most popular themes of medieval literature, in several languages. This volume is a comprehensive and up-to-date presentation of the story, including the first ever diplomatic edition of the text, replicating the exact state of the original manuscript. It also contains a new critical edition, complemented by extensive notes and a brief analytic preface.Edited by noted medievalist Barbara N. Sargent-Baur, The Romance of Tristran by Beroul and Beroul II: A Diplomatic Edition and a Critical Edition will be an essential resource for specialists interested in the study of this important text. An English translation of the Old French text appears in The Romance of Tristran by Beroul and Beroul II: Student Edition and English Translation.
