The first modern study of prehistoric religion in Ireland to draw on the combined evidence of archaeology, literature and folklore to illuminate practice and belief from the earliest human habitation in the island down to the advent of Christianity in the fifth century AD. An excellent book... a highly accessible and lively assessment of continuity and change in belief and religion from pre-Celtic times through to the arrival of St Patrick. ...Afine book and to be recommended to a wide readership, especially to all those who think that Irish history started in 1601.
