The project aims to study the way in which Bersuire, in the 14th century, translated Livy's History of Rome, a translation whose influence would be capital on the constitution of the French lexicon, political in particular, and the construction of a historical science, based on Western conceptions of Roman institutions. The team will also study the influence of this translation until the 16th century. and up to Spain and Italy. To carry out this large-scale study, it is first necessary to have access to the text of Bersuire, from which we have kept three Decades, i.e. groups of 10 books. The team will produce the critical edition, in digital version for decades III and IV. The recruitment of two doctoral students, guided by specialists in digital edition, will make it possible to carry out this essential step. Then specialists in literature, philology, lexicon, history, as well as two post-docs recruited within the framework of the project, will study the various fields considered.
