Dating the Gesta martyrum: a manuscript‐based approach

The gesta martyrum are an anonymous and disparate group of texts celebrating saints venerated in early medieval Rome as having been martyred in that city. This paper investigates the problems involved in placing these texts in their early medieval contexts. Since the beginning of the twentieth century, when scholarship moved away from attempts to identify a core of authentic ancient tradition in these early medieval narratives, most work on the corpus has concentrated on dating the composition of the accounts of individual martyrs. Given the sparsity of absolute chronological markers through references or citations in other written sources, this has inevitably rested on circumstantial evidence and the reconstruction of probable contexts for the redaction of specific works. This paper argues that much new light can be shed on the development of the cult of Roman martyrs if we shift the focus of our investigation from the origin and composition of the Urtexts to the surviving manuscript witnesses – all bar one eighth century or later – and the complex process of transmission which they document. The earliest copies of gesta martyrum, in both legendaries and other manuscripts, reveal surprisingly diverse contexts of transmission. Detailed investigation of Vienna National bibliothek 357, which Dufourcq argued contains a copy of a collection of martyr‐narratives available to Gregory the Great, shows that in fact this manuscript sheds light on interest in Roman martyrs north of the Alps in the late Carolingian period, and the networks of contact and communication through which information about the Roman martyrs was transmitted across time and space.
