The ultimate fate of Bran and his party in the medieval Irish tale Imram Brain maic Febail (‘The Voyage of Bran Mac Febal’) is that upon attaining the otherworld, when they try to return to the land of the living a great age has passed and the party are unable to set foot in the land without crumbling to dust. In other words, the Christian narrator denies them access to reincarnation. Bran is only allowed to pass on his story and then fade into legend, the narration finishing with the lines:
And from that hour his wanderings are not known.
The motif of immortality’s end appears in a modified form in the other famous Irish medieval legendary tale of the ‘Children of Lir’, who were transformed into immortal swans and cursed to travel Ireland for hundreds of years until ‘released’ by the coming of Christianity. The ‘Voyage of Bran’ leaves the state of Bran and his party indefinite, but the Children of Lir resume a withered mortal form or crumble to dust, though not usually before receiving christian confession and going to the Christian afterlife.
There are other Irish accounts of very long-lived members of ancient races receiving similar treatment. Some of these, such as in the pseudo-historical Christian narrative of the Lebor Gabála Érenn or ‘Book of Invasions’, and other related historical legends written in the middle ages, contain accounts of ‘Fintan’, one of the first settlers in Ireland who legends and stories claimed lived on in various animal and human forms until the coming of christianity. The Welsh medieval author Walter Map (De Nugis Curialum) left us the tale of King Herla which was based on similar themes as that of Bran, Finn and Caílte. The Middle Irish tale of mad pagan King Suibhne (‘Sweeney’) who literally flies around in a semi-animalistic form until released to heaven by a saint may also continue the Irish Christian tradition which told stories designed to counter a pagan belief in reincarnation.
The theme of submission of the pagan order to that of christianity occurs most strongly in the middle irish manuscript tales of the Acallam na Senórach (‘Colloquy of the Ancients’ or ‘Tales of the Elders of Ireland’ etc) which contains the majority of the ancient tales dealing with Finn and his band. It is set within a Christian framework in which the ancient giant warrior Caílte mac Rónáin (Finn’s nephew) relates tales of Finn and of the Tuatha Dé Danann to an interested St Patrick: By implication Caílte is exchanging the reality of an otherworldly existence in the pagan time frame with a Christianised legendary life in the hearafter.
All of these tales are careful to create a linkage between the old and new religious orders, again demonstrating conformity with the principles of the Christianised reformed laws of the Roman Empire propounded by Theodosius and his successors during the late classical period, during which time christianity was setting up shop in the Atlantic West of Europe. It was a theme of peaceful cohabitation of old and new which formed the skeleton of many medieval narrative and literary traditions, and managed to preserve the tenets of paganism, which after all seemed to explain everything which christianity could not and would continue to influence the folk traditions and beliefs down to modern times.
