In Errigal: Sacred Mountain, Cathal Searcaigh (one of Ireland's most celebrated poets) goes on a pilgrim path around Errigal and (in the active meditation of walking) summons up the spirit of this revered mountain, the largest in Ireland. In his "Passages of Light", we get a vivid and insightful word-journey around a mountain that has shaped the thinking of one of the most eminent poets in the Irish language. This book is a sure-footed mix of memoir, acute observation, wry humour and wisdom.
