Edward Story, bishop of Chichester 1478-1503, was a scholar who found himself, as bishop, embroilled in the events of both Church and State. His register, edited here, was intended to record the work of the administration of his diocese but it also reveals his involvement in national affairs, and gives windows into the life of the men and women of Sussex, including the talkative nuns of Ruspar, local heretics and the inhabitants of the bishop's prison. Medieval bishops were constantly travelling between their manors, and an appendix reconstucts Story's itinerary. The documents are presented here in translation with full introduction and elucidatory notes.
