Like Caesarius of Heisterbach, Thomas de Cantimpre, or Salimbene (until recently), Durandus is one of the most important 13thc. texts not to be readily available in a decent, well-edited English version (or even, except for Salimbene, in an excellent Latin edition). I've looked at a French version of the 'Rationale', and it's fair. As I recall, there was no proper scholarly introduction. I don't know if it's the same translation as the one Otfried mentions. My notes are at home. But neither the Neale/Webb, nor the Passmore, go very far towards a proper English edition/translation. What Otfried says about a forthcoming new Corpus Chris. ed. is the best news I've had in a long time. The 13thc. is not well-served. Why is that? Migne runs out after Innocent III (1216!). The most important 13thc. texts are often difficult to find, or to use for scholarly purposes, and to obtain for students.
