The recollections of Joseph Prost, an Austrian priest who initiated the Redemptorist parish missionary campaign in Ireland in 1851, provide a fascinating chronicle of the devotional revolution by one of its most earnest organisers. Tireless and uncompromising in his determination to save souls and reinvigorate the Roman Catholic faith, Prost often came into conflict with the parish clergy and his Redemptorist brethren. Though writing from memory two decades after his departure from Ireland, Prost supplies a detailed account of religious practices and social mores just after the Great Famine in Limerick, Derry, Wexford and many other Irish towns. The text has been translated from the German and fully annotated, with an introductory essay on Prost's career and the development of the parish mission movement. The publication of this memoir is a major contribution to Irish religious and cultural history.
