ABSTRACT
This chapter suggests that heresy will centre on historiographical and hagiographical sources because he believe, and will try to demonstrate, that the perception of heresy, in the Middle Ages, is closely linked to the conception of history. It focuses on Monastic Historiography, Identity Consciousness and Networks in Aquitaine and the Loire Valley, from the Carolingian Times to the Twelfth Century, which is the title of the current doctoral dissertation, under the supervision of Professor Philippe Depreux, at the University of Limoges. A further aim is to contribute new considerations to the debate about the possible dualism of eleventh-century heretics' in comparison with their twelfth-century successors, namely the famous Cathars', being that the use of an excessively broad definition of dualism' has led to eleventh-century sources being over-interpreted. The chapter examines testimonies from monastic historiographers who shared a more general clerical vision of the relation between past and present.
