Note 1 — Chapter XII · Race in Folklore and Myth

There is, however, no evidence to show that either of them is really the ‘she’ of whom we are in quest; but I have something to say about both as illustrating the other side of the theme, how the study of language may help mythology. This I have so far only illustrated by a reference to the equation of Ζεύς with Dyaus and their congeners. Within the range of Celtic legend the case is similar with Dôn, who figures on Welsh ground, as I have hinted, as mother of certain heroes of the oldest chapters of the Mabinogion. For it is from her that Gwydion, the bard and arch-magician, and Gofannon the smith his brother, are called sons of Dôn; and so in the case of Arianrhod, daughter of Dôn, mother of Ỻew, and owner of the sea-laved castle of Caer Arianrhod, not far distant from the prehistoric mound of Dinas Dinỻe, near the western mouth of the Menai Straits, as already mentioned in another chapter, p. 208 above. In Irish legend, we detect Dôn under the Irish form of her name, Danu or Donu, genitive Danann or Donann, and she is almost singular there in always being styled a divinity. From her the great mythical personages of Irish legend are called Tuatha Dé Danann, or ‘the Goddess Danu’s Tribes,’ and sometimes Fir Déa, or ‘the Men of the Divinity.’ The last stage in the Welsh history of Dôn consists of her translation to the skies, where the constellation of Cassiopeia is supposed to constitute Ỻys Dôn or Dôn’s Court, as the Corona Borealis is identified with Caer Arianrhod or ‘the Castle of Dôn’s Daughter’; but, as was perhaps fitting, the dimensions of both are reduced to comparative littleness by Caer Gwydion, ‘the Magician Gwydion’s Battlements,’ spread over the radiant expanse of the whole Milky Way1. Now the identification of this ancient goddess Danu or Dôn as that in whom the oldest legends of the Irish Goidels and the Welsh Goidels converge, has been the work not so much of mythology as of the science of language; for it was the latter that showed how to call back a little colouring into the vanishing lineaments of this faded ancestral divinity2.
