In this article, we will explore how the consumption of ancient letter collections and the development of letter-writing practices, known as dictaminal culture, reflect the grandeur of Durham Cathedral Priory. Located near the Scottish border and in a place with a historical influx of Scandinavians, Durham Cathedral Priory was a distant Benedictine community which stood as one of the most significant examples against the idea of cultural and educational periphery. It had one of the most comprehensive and multidisciplinary libraries in Western Europe, of which a significant part is still available and heavily invested in primary and secondary education. In that context, Durham Cathedral Library was a beacon of erudition, social and political connectiveness and humane growth. Linked to all those advancements, we can find both the consumption of ancient letter collections, which we will present as a product of various techniques and genres and the development of letter-writing techniques, which were inherited from late Antiquity but were transformed into something utterly new in medieval Europe. Therefore, we intend to demonstrate how Durham Cathedral Priory was an epistolary stronghold in all senses, which allowed it to grow further than any other distant and small community in England.
