W. B. Yeats 
The Celtic Twilight 

Best known for his poetry, William Butler Yeats dedicated a large part of his life to Irish folklore. His aim was to study the mythic and magical roots of the Irish tales, which resulted in this great ‘handful of dreams, ‘ as the author called it. ‘The Celtic Twilight’ invites you into the eerie and puckish world of fairies, ghosts, and spirits. Its title referred to the pre-dawn hours when the Druids performed their rituals. Yeats wrote the book from stories recounted to the poet by his friends, neighbors, and acquaintances.
