As we have just considered the Gaelic Divinities in their character as the Fairy-Folk of popular Gaelic tradition, so now we proceed to consider the Brythonic Divinities in the same way, beginning with the greatest of them all, Arthur. Even a superficial acquaintance with the Arthurian Legend shows how impossible it is to place upon it any one interpretation to the exclusion of other interpretations, for in one aspect Arthur is a Brythonic divinity and in another a sixth-century Brythonic chieftain. But the explanation of this double aspect seems easy enough when we regard the historical Arthur as a great hero, who, exactly as in so many parallel cases of national hero-worship, came--within a comparatively short time--to be enshrined in the imagination of the patriotic Brythons with all the attributes anciently belonging to a great Celtic god called Arthur.[266] The hero and the god were first confused, and then identified,[267] and hence arose that wonderful body of romance which we call Arthurian, and which has become the glory of English literature. Arthur in the character of a culture hero,[268] with god-like powers to instruct mortals in wisdom, and, also, as a being in some way related to the sun--as a sun-god perhaps--can well be considered the human-divine institutor of the mystic brotherhood known as the Round Table. We ought, probably, to consider Arthur, like Cuchulainn, as a god incarnate in a human body for the purpose of educating the race of men; and thus, while living as a man, related definitely and, apparently, consciously to the invisible gods or fairy-folk. Among the Aztecs and Peruvians in the New World, there was a widespread belief that great heroes who had once been men have now their celestial abode in the sun, and from time to time reincarnate to become teachers of their less developed brethren of our own race; and a belief of the same character existed among the Egyptians and other peoples of the Old World, including the Celts. It will be further shown, in our study of the Celtic Doctrine of Re-birth, that anciently among the Gaels and Brythons such heroes as Cuchulainn and Arthur were also considered reincarnate sun-divinities. As a being related to the sun, as a sun-god, Arthur is like Osiris, the Great Being, who with his brotherhood of great heroes and god-companions enters daily the underworld or Hades to battle against the demons and forces of evil,[269] even as the Tuatha De Danann battled against the Fomors. And the most important things in the traditions of the great Brythonic hero connect him directly with this strange world of subjectivity. First of all, his own father, Uthr Bendragon,[270] was a king of Hades, so that Arthur himself, being his child, is a direct descendant of this Otherworld. Second, the Arthurian Legend traces the origin of the Round Table back to Arthur's father, Hades being 'the realm whence all culture was fabled to have been derived'.[271] Third,
