The Dean of Exeter is the head of the Chapter of the Cathedral Church of Saint Peter in Exeter. The chapter was established by Bishop William Briwere (1224-44) who set up the offices of Dean and chancellor of Exeter Cathedral, allowing the chapter to elect those officers. This Note explores the possibility of Deans of Christianity existing in Exeter prior to Bishop Briwere having established the office.
