Celtic Hagiography and Saints Cults is an exploration of sanctity and the cult of saints in the Celtic-speaking regions of Europe. It is a multidisciplinary collection which brings together some of the most recent research on Celtic hagiography and saints' cults by a selection of leading international scholars in the field. In addition to surveying the topic and discussing the most prominent Celtic saints, there are also articles on such subjects as regional saints (Melangell, Moluag, Gerardine), the Celtic lives of Mary Magdalene and Martha, and on connections between the treatment of saints in the different Celtic regions. Celtic Hagiography draws on an extensive range of different sources in order to not only present a representative sample of case studies from all the Celtic regions but also to make the most recent research into Celtic saints' cults available to a wider audience. The volume thus provides the opportunity to investigate similarities, as well as differences, between the different Celtic societies, the development of Christianity in the Celtic regions and the production of hagiographies and religious literature.
