Cernunnos, this is because he is a lord of the underworld of fertility, the counterpart of which is the distant Elysium, to which Bran seems rather to belong. Thus, in presence of his head, time passes as a dream in feasting and joy. This is a true Elysian note, and the tabued door of the story is also suggestive of the tabus of Elysium, which when broken rob men of happiness.[353] As to the power of the head in protecting the land, this points to actual custom and belief regarding the relics of the dead and the power of divine images or sculptured heads.[354] The god Bran has become a king and law-giver in the _Mabinogion_ and the _Triads_,[355] 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.[356] 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.[357] Hence Bran's family is spoken of as one of the three saintly families of Prydein, and he is ancestor of many saints.[358] Branwen, "White Bosom," daughter of a sea-god, may be a sea-goddess, "Venus of the northern sea,"[359] unless with Mr. Nutt we connect her with the cauldron described in her legend,[360] 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.[361]
