L’acte diplomatique comme « preuve » dans l’écriture de l’histoire au travers de deux cas hispaniques L’Historia Compostellana et le Corpus Pelagianum

This article analyses the value given to the diplomatic act with regard to historiographic writing, using two Hispanic examples: the Historia Compostellana, a historical narrative about the episcopal seat of Saint-Jacques-de-Compostelle and the Corpus Pelagianum, a historiographic compilation realised by or at the request of the Bishop of Oviedo. These texts reveal a different conception of the status and role of the archival document in historiographic writing.
