Probably composed during the mid-15th century, this describes the love and tragic death of the poet Cearbhall O Dalaigh of Corcomroe in County Clare and Fearbhlaidh, the daughter of Seamus, king of Scotland. Although much is fictional, derived from early Irish myth and legend, some of the characters are based on historical figures. The first translation to appear in English, this includes both the prose and poetry found in the manuscript.
