The Céli Dé (`clients of God'), sometimes referred to as the Culdees, comprise the group of monks who first appeared in Ireland in the eighth century in association with St Máel Ruain of Tallaght. Although influential and important in the development of the monastic tradition in Ireland, they have been neglected in general histories. This book offers an investigation into the movement.
