The theory that Lludd Llaw Ereint or Lodens Lamargentios represents Nodens (Nuada) L=amargentios, the change being the result of alliteration, has been contested,357 while if the Welsh Lludd and Nudd were identical it is strange that they should have become distinct personalities, Gwyn, son of Nudd, being the lover of Creiddylad, daughter of Lludd,358 unless in some earlier myth their love was that of brother and sister. Lludd is also confused or is identical with Llyr, just as the Irish Ler is with Alloid. He is probably the son of Beli who, in the tale of Lludd and Llevelys, by the advice of Llevelys rids his country of three plagues.359 These are, first, the Coranians who hear every whisper, and whom he destroys by throwing over them water in which certain insects given him by Levelys have been bruised. The second is a shriek on May-eve which makes land and water barren, and is caused by a dragon which attacks the dragon of the land. These Lludd captures and imprisons at Dinas Emreis, where they afterwards cause trouble to Vortigern at the building of his castle. The third is that of the disappearance of a year's supply of food by a magician, who lulls every one to sleep and who is captured by Lludd. Though the Coranians appear in the Triads as a hostile tribe,360 they may have been a supernatural folk, since their name is perhaps derived from còr, "dwarf," and they are now regarded as mischievous fairies.361 They may thus be analogous to the Fomorians, and their story, like that of the dragon and the magician who produce blight and loss of food, may be based on older myth or ritual embodying the belief in powers hostile to fertility, though it is not clear why those powers should be most active on May-day. But this may be a misunderstanding, and the dragons are overcome on May-eve. The references in the tale to Lludd's generosity and liberality in giving food may reflect his function as a god of growth, but, like other euhemerised gods, he is also called a mighty warrior, and is said to have rebuilt the walls of Caer Ludd (London), his name still surviving in "Ludgate Hill," where he was buried.362 This legend doubtless points to some ancient cult of Lludd at this spot.
Nudd already discussed under his title Nodons, is less prominent than his son Gwyn, whose fight with Gwthur we have explained as a mythic explanation of ritual combats for the increase of fertility. He also appears as a hunter and as a great warrior,363 "the hope of armies," and thus he may be a god of fertility who became a god of war and the chase. But legend associated him with Annwfn, and regarded him, like the Tuatha Déa, as a king of fairyland.364 In the legend of S. Collen, the saint tells two men, whom he overhears speaking of Gwyn and the fairies, that these are demons. "Thou shalt receive a reproof from Gwyn," said one of them, and soon after Collen was summoned to meet the king of Annwfn on Glastonbury Tor. He climbed the hill with a flask of holy water, and saw on its top a splendid castle, with crowds of beautiful and youthful folk, while the air resounded with music. He was brought to Gwyn, who politely offered him food, but "I will not eat of the leaves of the tree," cried the saint; and when he was asked to admire the dresses of the crowd, all he would say was that the red signified burning, the blue coldness. Then he threw the holy water over them, and nothing was left but the bare hillside.365 Though Gwyn's court on Glastonbury is a local Celtic Elysium, which was actually located there, the story marks the hostility of the Church to the cult of Gwyn, perhaps practised on hilltops, and this is further seen in the belief that he hunts souls of the wicked and is connected with Annwfn in its later sense of hell. But a mediant view is found in Kulhwych, where it is said of him that he restrains the demons of hell lest they should destroy the people of this world. In the Triads he is, like other gods, a great magician and astrologer.366
Another group, unknown to the Mabinogion, save that Taliesin is one of the bearers of Bran's head, is found in the Book of Taliesin and in the late story of Taliesin. These, like the Arthur cycle, often refer to personages of the Mabinogion; hence we gather that local groups of gods, originally distinct, were later mingled in story, the references in the poems reflecting this mingling. Late as is the Hanes Taliesin or story of Taliesin, and expressed as much of it is in a Märchen formula, it is based on old myths about Cerridwen and Taliesin of which its compiler made use, following an old tradition already stereotyped in one of the poems in the Märchen formula of the Transformation Combat.367 But the mythical fragments are also mingled with traditions regarding the sixth century poet Taliesin. The older saga was perhaps developed in a district south of the Dyfi estuary.368 In Lake Tegid dwell Tegid Voel, Cerridwen, and their children—the fair maiden Creirwy, Morvran, and the ugly Avagddu. To give Avagddu knowledge, his mother prepares a cauldron of inspiration from which three drops of inspiration will be produced. These fall on the finger of Gwion, whom she set to stir it. He put the finger in his mouth, and thus acquired the inspiration. He fled, and Cerridwen pursued, the rest of the story being accommodated to the Transformation Combat formula. Finally, Cerridwen as a hen swallows Gwion as a grain of wheat, and bears him as a child, whom she throws into the sea. Elphin, who rescues him, calls him Taliesin, and brings him up as a bard.369
The water-world of Tegid is a submarine Elysium with the customary cauldron of inspiration, regeneration, and fertility, like the cauldron associated with a water-world in the Mabinogion. "Shall not my chair be defended from the cauldron of Cerridwen," runs a line in a Taliesin poem, while another speaks of her chair, which was probably in Elysium like that of Taliesin himself in Caer Sidi.370 Further references to her connection with poetry show that she may have been worshipped by bards, her cauldron being the source of their inspiration.371 Her anger at Gwion may point to some form of the Celtic myth of the theft of the elements of culture from the gods' land. But the cauldron was first of all associated with a fertility cult,372 and Cerridwen must therefore once have been a goddess of fertility, who, like Brigit, was later worshipped by bards. She may also have been a corn-goddess, since she is called a goddess of grain, and tradition associates the pig—a common embodiment of the corn-spirit—with her.373 If the tradition is correct, this would be an instance, like that of Demeter and the pig, of an animal embodiment of the corn-spirit being connected with a later anthropomorphic corn-goddess.
Taliesin was probably an old god of poetic inspiration confused with the sixth century poet of the same name, perhaps because this boastful poet identified himself or was identified by other bards with the gods. He speaks of his "splendid chair, inspiration of fluent and urgent song" in Caer Sidi or Elysium, and, speaking in the god's name or identifying himself with him, describes his presence with Llew, Bran, Gwydion, and others, as well as his creation and his enchantment before he became immortal.374
