This paper takes its cue from recent theoretical developments in religious and cultural studies to investigate the issues of materiality and religion as lived religion in Late Antiquity, the topic of the workshop. As a case study, I shall focus on quotidian religion as experienced by the congregations of Caesarius of Arles. Caesarius’ sermons, preached at a number of locations beside Arles itself, provide a fascinating (if problematic) source for investigating both urban and rural culture. In a famous sermon (Serm. 6) Caesarius compares religious instruction with learning about viticulture; this paper will explore how technologies of knowledge and practice were understood, and incorporated into daily life, by both preacher and audience.
