W.B.Yeats was an occultist, writer, poet, and Irish Celtic nationalist.....
Yeats was interested in folktales as a part of an exploration of national heritage and for the revival of Celtic identity. His study with George Russell and Douglas Hyde of Irish legends and tales was published in 1888 under the title Fairy and Folk Tales of the Irish Peasantry. Yeats assembled for children a less detailed version, Irish Fairy Tales, which appeared in 1892. The Wanderings Of Oisin And Other Poems (1889), took its subject from Irish mythology.
