The surviving body of ancient letters offers the reader a stunning variety of material, ranging from the everyday letters preserved among the Oxyrhynchus papyri to imperial rescripts, New Testament Epistles, fictional or pseudepigraphical letters and a wealth of missives on almost every conceivable subject. They offer us a unique insight into ancient practices in the fields of politics, literature, philosophy, medicine and many other areas. This collection presents a series of case studies in ancient letters, asking how each letter writer manipulates the epistolary tradition, why he chose the letter form over any other, and what effect the publication of volumes of collected letters might have had upon a reader's engagement with epistolary works. This volume is the first of its kind on ancient letters in any language, and it brings together both well-established and promising young scholars currently working in the fields of ancient literature, history, philosophy and medicine to engage in a shared debate about this most adaptable and 'interdisciplinary' of genres.
