Renee Curtis's three-volume critical edition of the Prose Tristan is the only edition of this very important medieval work ever published; until the first volume appeared in 1963, the work was only accessible in the form of a few fragments which had been edited and a summary of the romance made by E. Loseth in 1891. Dr Curtis's edition is based on a complete collation of all the manuscripts and this led her to choose the Carpentras manuscript 404 as the basis of her edition. This second volume appeared in1976. Professor Brian Woledge, the eminent medievalislt, wrote of the first volume in Erasmus: "The publication of this book is an event of some importance in Arthurian studies. The Prose Tristan was one of the most widely read works in medieval France; written between1215 and 1235, it continued to be copied until the end of the Middle Ages and its popularity lasted another hundred years in printed editions. It was in fact in prose rather than in poetic form that the legend was known.... Dr Curtis is to warmly congratulated on undertaking this important task"
