For any type of translation, the concept of movement makes it possible to take into account the many successive states of a given text and to interpret its variations. The documents examined here each bear witness to the transformations they have undergone when, changing language, style or period, they changed audience. This book presents a selection of papers presented at the seventh international conference on the theory and practice of the translation of documents in the Middle Ages, held at Paris III University - New Sorbonne in July 2004. The period covered by these documents and their translations extends from Antiquity to the present day. A total of twenty-eight studies are presented. The richess of the domains covered, the highly technical analysis, and the consideration given to questioning modern translation techniques, illustrate the remarkable vitality of current studies relating to the multiple aspects of the translation of medieval documents.
