Not many folk-tales have been preserved in which Gwyn is mentioned by name. His memory has lingered longest and latest in the fairy-haunted Vale of Neath, so close to his “ridge, the Tawë abode ... not the nearest Tawë ... but that Tawë which is the farthest”. But it may be understood whenever the king of the fairies is mentioned. As the last of the greater gods of the old mythology, he has been endowed by popular fancy with the rule of all the varied fairy population of Britain, so far, at least, as it is of Celtic or pre-Celtic origin. For some of the fairies most famous in English literature are Teutonic. King Oberon derives his name, through the French _fabliaux_, from Elberich, the dwarf king of the _Niebelungenlied_,[552] though his queen, Titania, was probably named out of Ovid’s _Metamorphoses_.[553] Puck, another of Shakespeare’s fays, is merely the personification of his race, the “pwccas” of Wales, “pookas” of Ireland, “poakes” of Worcestershire, and “pixies” of the West of England.[554] It is Wales that at the present time preserves the most numerous and diverse collection of fairies. Some of them are beautiful, some hideous; some kindly, some malevolent. There are the gentle damsels of the lakes and streams called Gwragedd Annwn, and the fierce and cruel mountain fairies known as the Gwyllion. There are the household sprites called Bwbachod, like the Scotch and English “brownies”; the Coblynau, or gnomes of the mines (called “knockers” in Cornwall); and the Ellyllon, or elves, of whom the pwccas are a branch.[555] In the North of England the spirits belong more wholly to the lower type. The bogles, brownies, killmoulis, redcaps, and their like seem little akin to the higher, Aryan-seeming fairies. The Welsh bwbach, too, is described as brown and hairy, and the coblynau as black or copper-faced. We shall hardly do wrong in regarding such spectres as the degraded gods of a pre-Aryan race, like the Irish leprechauns and pookas, who have nothing in common with the still beautiful, still noble figures of the Tuatha Dé Danann.
