Professor Séamas ÓCatháin's monumental study of the Festival of Brigit - Imbolc, February 1st - updated, extended, and published in a new edition, in honour of Ireland's newest national holiday. Brigit was one of three great saints of early Irish Christianity, alongside Patrick, the patron saint of Ireland, and Colm Cille (Columba), Irish colonizer of Scotland and founder of Iona. By tradition, Saints' Day festivals and other Holy Days were celebrated over twenty-four hours, starting on the eve of the feast and continuing through the night and through the following day. Thus the Festival of Brigit includes Oíche Fhéile Bríde (St Brigit's Eve) and Lá Fhéile Bríde (St Brigit's Day) - on 31st January and 1st February respectively. However, these are not the oldest names associated with this festival in Irish tradition, for in earlier pre-Christian times it was called Imbolc - a word whose basic meaning has much to do with milking and milk-production.This book views Brigit - the Celtic goddess and the Christian-era Saint - not merely in an Irish context, but also in an international and western European context. It attempts to uncover the motivation of previous generations, both within Ireland and beyond it, in sustaining and preserving ancient practices and beliefs, and highlights how fundamentally important folk culture is to our understanding of the past.
