With Gwydion, too, have disappeared the whole of the characters connected with him in that portion of the Mabinogi of Mâth, Son of Mathonwy, which recounts the myth of the birth of the sun-god. Neither Mâth himself, nor Lleu Llaw Gyffes, nor Dylan, nor their mother, Arianrod, play any more part; they have vanished as completely as Gwydion. But the essence of the myth of which they were the figures remains intact. Gwydion was the father by his sister Arianrod, wife of a waning heaven-god called Nwyvre (Space), of twin sons, Lleu, a god of light, and Dylan, a god of darkness; and we find this same story woven into the very innermost texture of the legend of Arthur.[387] The new Arianrod, though called “Morgawse” by Sir Thomas Malory[388], and “Anna” by Geoffrey of Monmouth[389], is known to earlier Welsh myth as “Gwyar”[390]. She was the sister of Arthur and the wife of the sky-god, Lludd, and her name, which means “shed blood” or “gore”, reminds us of the relationship of the Morrígú, the war-goddess of the Gaels, to the heaven-god Nuada[391]. The new Lleu Llaw Gyffes is called Gwalchmei, that is, the “Falcon of May”[392], and the new Dylan is Medrawt, at once Arthur’s son and Gwalchmei’s brother, and the bitterest enemy of both[393]. Besides these “old friends with new faces”, Arthur brings with him into prominence a fresh Pantheon, most of whom also replace the older gods of the heavens and earth and the regions under the earth. The Zeus of Arthur’s cycle is called Myrddin, who passed into the Norman-French romances as “Merlin”. All the myths told of him bear witness to his high estate. The first name of Britain, before it was inhabited, was, we learn from a triad, _Clas Myrddin_, that is, “Myrddin’s Enclosure”.[394] He is given a wife whose attributes recall those of the consorts of Nuada and Lludd. She is described as the only daughter of Coel—the British name of the Gaulish _Camulus_, a god of war and the sky—and was called Elen Lwyddawg, that is, “Elen, Leader of Hosts”. Her memory is still preserved in Wales in connection with ancient roadways; such names as _Ffordd Elen_ (“Elen’s Road”) and _Sarn Elen_ (“Elen’s Causeway”) seem to show that the paths on which armies marched were ascribed or dedicated to her.[395] As Myrddin’s wife, she is credited with having founded the town of Carmarthen (_Caer Myrddin_), as well as the “highest fortress in Arvon”, which must have been the site near Beddgelert still called _Dinas Emrys_, the “Town of Emrys”, one of Myrddin’s epithets or names.[396]
