We find many stories of gods, demigods, and heroes tangled up together in folk-tales and in the literature they have influenced. It is sometimes difficult to distinguish between them, and again it is interesting to note how the hero-myth has been converted into the tale of a god. Celtic romances and folk-supernaturalism give many stories of gods, demigods, and heroes of superhuman force. It would be interesting if one could trace them to their ultimate sources and discover how much they have been suggested or influenced by classical mythology. In _Fiction of the Irish Celts_, by Patrick Kennedy, are numberless stories of the Fianna Eironn, or Heroes of Ireland, some of whom really flourished in the third century and whose adventures were the favorite stories of the kings and chiefs as sung by the ancient bards. Kennedy also retells many of the Ossianic legends. In _Bardic Stories of Ireland_ he relates the exploits of personages dating back to druidic times and earlier, who reflect the remote stages of the legendary history of the people, such as the antique King Fergus, who was given supernatural power by the fairies and slew the sea-monster; Cormac, who did many doughty deeds assisted by the powers of the Immortals, and many others. W. B. Yeats, in his _Stories of Red Ranrahan_, gives us glimpses of an Irish François Villon, a man of wandering nature, of human frailties, yet with a divine gift of song. Lady Gregory tells the wonderful saga of Cuchulain, the hero-god of Ireland, in _Cuchulain of Muirthemne_, which W. B. Yeats calls "perhaps the best book that has ever come out of Ireland." It was his mother Dechtire that drank the soul of Lugh of the Strong Hand, as he flew into her wine-cup in the form of a Mayfly, so that she was bound by enchantment and carried away with her fifty maidens as a flock of lovely birds. When anger came upon him the hero light would shine about his head, he understood all the arts of the druids and had supernatural beauty and strength in battle. Cuchulain, the Hound of Ulster, and his Red Branch have filled the legendry of Ireland with wonder.
