Introduction

This chapter contextualizes the phenomenon of demonic possession and discusses its medieval interpretations as well as demonstrating its connections to fields of study such as heresy, demonology, and witchcraft. It sets out the main analytical concept of lived religion and shows how demons were integral within it, intersecting cultural, communal, and individual levels. Religion created a performative space and demonic presence was a fluid and multifaceted category within it. This chapter introduces the corpus of source material and methodological elements of canonization processes: the final records were an outcome of collaboration between lay witnesses and the inquisitorial committee, an amalgam of personal choices in the use of rhetoric, communal memories of actual past events, and the demands of canon law and the miracle genre. Therefore, depositions reveal inconsistencies in the universalizing discourse of the Church and manifest local nuances in the way people lived their religion.
