in the Mabinogion and the Triads,303 while Geoffrey of Monmouth describes how Belinus and Brennus, in the Welsh version Beli and Bran, dispute the crown of Britain, are reconciled, and finally conquer Gaul and Rome.304 The mythic Bran is confused with Brennus, leader of the Gauls against Rome in 390 B.C., and Belinus may be the god Belenos, as well as Beli, father of Lludd and Caswallawn. But Bran also figures as a Christian missionary. He is described as hostage at Rome for his son Caradawc, returning thence as preacher of Christianity to the Cymry—a legend arising out of a misunderstanding of his epithet "Blessed" and a confusing of his son with the historic Caractacus.305 Hence Bran's family is spoken of as one of the three saintly families of Prydein, and he is ancestor of many saints.306
Branwen, "White Bosom," daughter of a sea-god, may be a sea-goddess, "Venus of the northern sea,"307 unless with Mr. Nutt we connect her with the cauldron described in her legend,308 symbol of an orgiastic cult, and regard her as a goddess of fertility. But the connection is not clear in the story, though in some earlier myth the cauldron may have been her property. As Brangwaine, she reappears in romance, giving a love-potion to Tristram—perhaps a reminiscence of her former functions as a goddess of love, or earlier of fertility. In the Mabinogion she is buried in Anglesey at Ynys Bronwen, where a cairn with bones discovered in 1813 was held to be the grave and remains of Branwen.309
The children of Dôn, the equivalent of Danu, and probably like her, a goddess of fertility, are Gwydion, Gilvæthwy, Amæthon, Govannon, and Arianrhod, with her sons, Dylan and Llew.310 These correspond, therefore, in part to the Tuatha Déa, though the only members of the group who bear names similar to the Irish gods are Govannon (= Goibniu) and possibly Llew (= Lug). Gwydion as a culture-god corresponds to Ogma. In the Triads Beli is called father of Arianrhod,311 and assuming that this Arianrhod is identical with the daughter of Dôn, Professor Rh^ys regards Beli as husband of Dôn. But the identification is far from certain, and the theory built upon it that Beli is one with the Irish Bile, and that both are lords of a dark underworld, has already been found precarious.312 In later belief Dôn was associated with the stars, the constellation Cassiopeia being called her court. She is described as "wise" in a Taliesin poem.313
This group of divinities is met with mainly in the Mabinogi of Math, which turns upon Gilvæthwy's illicit love of Math's "foot-holder" Goewin. To assist him in his amour, Gwydion, by a magical trick, procures for Math from the court of Pryderi certain swine sent him by Arawn, king of Annwfn. In the battle which follows when the trick is discovered, Gwydion slays Pryderi by enchantment. Math now discovers that Gilvæthwy has seduced Goewin, and transforms him and Gwydion successively into deer, swine, and wolves. Restored to human form, Gwydion proposes that Arianrhod should be Math's foot-holder, but Math by a magic test discovers that she is not a virgin. She bears two sons, Dylan, fostered by Math, and another whom Gwydion nurtures and for whom he afterwards by a trick obtains a name from Arianrhod, who had sworn never to name him. The name is Llew Llaw Gyffes, "Lion of the Sure Hand." By magic, Math and Gwydion form a wife for Llew out of flowers. She is called Blodeuwedd, and later, at the instigation of a lover, Gronw, she discovers how Llew can be killed. Gronw attacks and wounds him, and he flies off as an eagle. Gwydion seeks for Llew, discovers him, and retransforms him to human shape. Then he changes Blodeuwedd into an owl, and slays Gronw.314 Several independent tales have gone to the formation of this Mabinogi, but we are concerned here merely with the light it may throw on the divine characters who figure in it.
Math or Math Hen, "the Ancient,"315 is probably an old divinity of Gwyned, of which he is called lord. He is a king and a magician, pre-eminent in wizardry, which he teaches to Gwydion, and in a Triad he is called one of the great men of magic and metamorphosis of Britain.316 More important are his traits of goodness to the suffering, and justice with no trace of vengeance to the wrong-doer. Whether these are derived from his character as a god or from the Celtic kingly ideal, it is impossible to say, though the former is by no means unlikely. Possibly his supreme magical powers make him the equivalent of the Irish "god of Druidism," but this is uncertain, since all gods were more or less dowered with these.
Gwydion's magical powers are abundantly illustrated in the tale. At Pryderi's court he changes fungus into horses and dogs, and afterwards slays Pryderi by power of enchantments; he produces a fleet by magic before Arianrhod's castle; with Math's help he forms Blodeuwedd out of flowers; he gives Llew his natural shape when he finds him as a wasted eagle on a tree, his flesh and the worms breeding in it dropping from him; he transforms the faithless Blodeuwedd into an owl. Some of these and other deeds are referred to in the Taliesin poems, while Taliesin describes himself as enchanted by Gwydion.317 In the Triads he is one of the three great astrologers of Prydein, and this emphasis laid on his powers of divination is significant when it is considered that his name may be derived from a root vet, giving words meaning "saying" or "poetry," while cognate words are Irish fáith, "a prophet" or "poet," German wuth, "rage," and the name of Odinn.318 The name is suggestive of the ecstasy of inspiration producing prophetic and poetic utterance. In the Mabinogion he is a mighty bard, and in a poem, he, under the name of Gweir, is imprisoned in the Other-world, and there becomes a bard, thus receiving inspiration from the gods' land.319 He is the ideal fáith—diviner, prophet, and poet, and thus the god of those professing these arts. Strabo describes how the Celtic vates (fáith) was also a philosopher, and this character is given in a poem to Seon (probably = Gwydion), whose artists are poets and magicians.320 But he is also a culture-god, bringing swine to men from the gods' land. For though Pryderi is described as a mortal who has himself received the swine from Annwfn (Elysium), there is no doubt that he himself was a lord of Annwfn, and it was probably on account of Gwydion's theft from Annwfn that he, as Gweir, was imprisoned there "through the messenger of Pwyll and Pryderi."321 A raid is here made directly on the god's land for the benefit of men, and it is unsuccessful, but in the Mabinogi a different version of the raid is told. Perhaps Gwydion also brought kine from Annwfn, since he is called one of the three herds of Britain,322 while he himself may once have been an animal god, then an anthropomorphic deity associated with animals. Thus in the Mabinogi, when Gwydion flees with the swine, he rests each night at a place one of the syllables of which is Moch, "swine"—an ætiological myth explaining why places which were once sites of the cult of a swine-god, afterwards worshipped as Gwydion, were so called.
Gwydion has also a tricky, fraudulent character in the Mabinogi, and although "in his life there was counsel," yet he had a "vicious muse."323 It is also implied that he is lover
