Prophecy, Fate and Memory in the Early and Medieval Celtic World brings together a collection of studies that closely explore aspects of culture and history of Celtic-speaking nations. Non-narrative sources and cross-disciplinary approaches shed new light on traditional questions concerning commemoration, sources of political authority, and the nature of religious identity. Leading scholars and early-career researchers bring to bear hermeneutics from studies of religion and literary criticism alongside more traditional philological and historical methodologies. All the studies in this book bring to their particular tasks an acknowledgement of the importance of religion in the worldview of antiquity and the Middle Ages. Their approaches reflect a critical turn in Celtic studies that has proved immensely productive across the last two decades.
