A Companion to Byzantine Epistolography introduces and contextualizes the culture of Byzantine letter-writing from various socio-historical, material and literary angles. While this culture was long regarded as an ivory-tower pastime of intellectual elites, the eighteen essays in this volume, authored by leading experts in the field, show that epistolography had a vital presence in many areas of Byzantine society, literature and art. The chapters offer discussions of different types of letters and intersections with non-epistolary genres, their social functions as media of communication and performance, their representations in visual and narrative genres, and their uses in modern scholarship. The volume thus contributes to a more nuanced understanding of letter-writing in the Byzantine Empire and beyond.
