Ancient Legends, Mystic Charms, and Superstitions of Ireland was published in 1887. In it, Lady Wilde lets us look into the minds of the Irish peasantry of the time. She did this by interviewing the elders of a dying faith now referred to as the “fairy religion,” or sometimes simply as witchcraft. Sections of the book have not always been considered authoritative according to some sources, such as Sacred-Texts.com.
This should be taken in context, however. In the preface, Lady Wilde separates herself from the individuals whose stories she’s about to share. She explains the historical and cultural importance of the tales themselves. Wilde then reminds the reader that this might have been the last chance for anyone to record the stories from the dying generation before they would be lost forever. She also offers other reasons for being interested in the pagan subject as well, including a love for anything Irish. Finally, she concludes her apologetic preface by reminding the reader that she’s a woman.
