Christianity and Early Irish Myth

For my research project, I will be analyzing the Christian themes present in Irish mythology to determine the influence that Christianity had on the early pagan beliefs of the Irish people The arrival of Christianity on the island and the subsequent writing of Irish history by those Christians allowed them to portray the religion and beliefs of the Irish as they wished.  Thus, today our view of Irish beliefs is heavily influenced by Christian views. We do not have any of the original Irish myths that were passed down through oral tradition.  By analyzing Christian texts for common themes and then looking into the surviving Irish mythos for resemblances or traces of these themes, I hope to see just how much of the Irish myths were affected by Christianity, and if there is any hope of reconstructing something along the lines of what the original myths might have looked like.
