This observation respecting the mysterious language used by fairies recalls again the medieval story of Elidurus. The example of fairy words there given by Giraldus is thought by the learned rector of Llanarmon[51] to be 'a mixture of Irish and Welsh. The letter U, with which each of the words begins, is, probably, no more than the representative of an indistinct sound like the E mute of the French, and which those whose language and manners are vulgar often prefix to words indifferently. If, then, they be read dor dorum, and halgein dorum, dor and halgein are nearly dwr (or, as it is pronounced, door) and halen, the Welsh words for water and salt respectively. Dorum therefore is equivalent to "give me," and the Irish expression for "give me" is thorum; the Welsh dyro i mi. The order of the words, however, is reversed. The order should be thorum dor, and thorum halen in Irish, and in Welsh dyro i mi ddwr, and dyro i mi halen, but was, perhaps, reversed intentionally by the narrator, to make his tale the more marvellous.'[52] FOOTNOTES: [51] Rev.

Not only does his skeleton serve for Mary Lwyds[53] and the like, but his spirit flits. The Welsh fairies seem very fond of going horseback. An old woman in the Vale of Neath told Mrs. Williams, who told Thomas Keightley, that she had seen fairies to the number of hundreds, mounted on little white horses, not bigger than dogs, and riding four abreast. This was about dusk, and the fairy equestrians passed quite close to her, in fact less than a quarter of a mile away. Another old woman asserted that her father had often seen the fairies riding in the air on little white horses; but he never saw them come to the ground. He heard their music sounding in the air as they galloped by. There is a tradition among the Glamorgan peasantry of a fairy battle fought on the mountain between Merthyr and Aberdare, in which the pigmy combatants were on horseback. There appeared to be two armies, one of which was mounted on milk-white steeds, and the other on horses of jet-black. They rode at each other with the utmost fury, and their swords could be seen flashing in the air like so many penknife blades. The army on the white horses won the day, and drove the black-mounted force from the field. The whole scene then disappeared in a light mist. FOOTNOTE: [53] See Index. VI.
