The realistic theory of the origin of the Tylwyth Teg must be mentioned respectfully, because among its advocates have been men of culture and good sense. This theory presumes that the first fairies were men and women of mortal flesh and blood, and that the later superstitions are a mere echo of tales which first were told of real beings. In quasi-support of this theory, there is a well-authenticated tradition of a race of beings who, in the middle of the sixteenth century, inhabited the Wood of the Great Dark Wood (Coed y Dugoed Mawr) in Merionethshire, and who were called the Red Fairies. They lived in dens in the ground, had fiery red hair and long strong arms, and stole sheep and cattle by night. There are cottages in Cemmaes parish, near the Wood of the Great Dark Wood, with scythes in the chimneys, which were put there to keep these terrible beings out. One Christmas eve a valiant knight named Baron Owen headed a company of warriors who assailed the Red Fairies, and found them flesh and blood. The Baron hung a hundred of them; but spared the women, one of whom begged hard for the life of her son. The Baron refused her prayer, whereupon she opened her breast and shrieked, 'This breast has nursed other sons than he, who will yet wash their hands in thy blood, Baron Owen!' Not very long thereafter, the Baron was waylaid at a certain spot by the sons of the 'fairy' woman, who washed their hands in his warm and reeking blood, in fulfilment of their mother's threat. And to this day that spot goes by the name of Llidiart y Barwn (the Baron's Gate); any peasant of the neighbourhood will tell you the story, as one told it to me. There is of course no better foundation for the fairy features of it than the fancies of the ignorant mind, but the legend itself is--very nearly in this shape--historical. The beings in question were a band of outlaws, who might naturally find it to their interest to foster belief in their supernatural powers.
