This excellent book is a worthy successor to Myles Dillon 'Early Irish Literature' (1948). In addition to her introductions to each genre, the author summarizes the most important stories in each. These summaries show more clearly than any other method could how very different early Irish society--its organization, its laws, and its interests--were from those of contemporary English and Continental and certainly from those of the modern world. Identifying a common vision with other cultures is not so difficult when examining Ireland's early religious literature, but one has to dig deep into the more alien secular literature to identify a shared understanding even though the earliest versions of these stories were transcribed in Irish monasteries by Christian scribes. This short but dense study is a must-have book for anyone interested in early Irish society and should be read in conjunction with the stories she describes, which can be found in Cross and Slover 'Ancient Irish Tales', Jeffrey Gantz 'Early Irish Myths and Sagas', and Koch and Carey 'The Celtic Heroic Age', and Green and O'Connor 'A Golden Treasury of Irish Poetry, A.D. 600-1200.
