In this case we think Arthur is very clearly a ruler of the spirit realm, for, like the great Tuatha De Danann king Dagda, he can command its fairy-like inhabitants, and his army is an army of spirits or fairies. The unknown author of _Kulhwch_, like Spenser in modern times in his _Faerie Queene_, seems to have made the Island of Britain the realm of Faerie--the Celtic Otherworld--and Arthur its king. But let us take a look at more of the men pledged to Kulhwch from among Arthur's followers: Clust the son of Clustveinad, who possessed clairaudient faculties of so extraordinary a kind that 'though he were buried seven cubits beneath the earth, he would hear the ant fifty miles off rise from her nest in the morning'; and the wonderful Kai, who could live nine days and nine nights under water, for his breath lasted this long, and he could exist the same length of time without sleep. 'A wound from Kai's sword no physician could heal.' And at will he was as tall as the highest tree in the forest. 'And he had another peculiarity: so great was the heat of his nature, that, when it rained hardest, whatever he carried remained dry for a handbreadth above and a handbreadth below his hand; and when his companions were coldest, it was to them as fuel with which to light their fire.' Yet besides all these strange knights, Arthur commanded a being who is without any reasonable doubt a god or ruler of the subjective realm--'Gwynn ab Nudd, whom God has placed over the brood of devils in Annwn, lest they should destroy the present race. He will never be spared thence.' Whatever each one of us may think of this wonderful assembly of warriors and heroes who recognized in Arthur their chief, they are certainly not beings of the ordinary type,--in fact they seem not of this world, but of that hidden land to which we all shall one day journey.[293] But to avoid too much conjecture and to speak with a degree of scientific exactness as to how Arthur and these companions of his are to be considered, let us undertake a brief investigation into the mythological character and nature of the chief one of them next to the great hero--Gwynn ab Nudd. Professor J. Loth has said that 'nothing shows better the evolution of mythological personages than the history of Gwynn';[294] and in Irish we have the equivalent form of Nudd in the name Nuada--famous for having had a hand of silver; and Nuada of the Silver Hand was a king of the Tuatha De Danann. The same authority thus describes Gwynn, the son of Nudd:--'Gwynn, like his father Nudd, is an ancient god of the Britons and of the Gaels. Christian priests have made of him a demon. The people persisted in regarding him as a powerful and rich king, the sovereign of supernatural beings.'[295] And referring to Gwynn, Professor Loth in his early edition of _Kulhwch_ says:--'Our author has had an original idea: he has left him in hell, to which place Christianity had made him descend, but for a motive which does him the
