" On the conversion of the European tribes to Christianity the ancient pagan worship was by no means incontinently abandoned. So wholesale had been the conversion of many peoples, whose chiefs or rulers had accepted the new faith on their behalf in a summary manner, that it would be absurd to suppose that any, general acquiescence in the new gospel immediately took place. Indeed, the old beliefs lurked in many neighbourhoods, and even a renaissance of some of them occurred in more than one area. Little by little, however, the Church succeeded in rooting out the public worship of the old pagan deities, but it found it quite impossible to effect an entire reversion of pagan ways, and in the end compromised by exalting the ancient deities to the position of saints in its calendar, either officially, or by usage. In the popular mind, however, these remained as the fairies of woodland and stream, whose worship in a broken-down form still flourished at wayside wells and forest shrines. The Matres, or Mother gods, particularly those of Celtic France and Ireland, the former of which had come to be Romanized, became the bonnes dames of folklore, while the dusii and pilosi, or hairy house-sprites, were so commonly paid tribute that the Church introduced a special question concerning them into its catechism of persons suspected of pagan practice. Nevertheless, the Roman Church, at a somewhat later era, reversed its older and more catholic policy, and sternly set its face against the cultus of paganism in Europe, stigmatizing the several kinds of spirits and derelict gods who were the objects of its worship as demons and devils, whom mankind must eschew with the most pious care if it were to avoid damnation.

" Only hinted at in some of these tales, and clearly stated in others, it is apparent that there was a long and continuing conflict between paganism and Christianity in the early centuries A.D. This may also be the explanation behind other well creation tales, such as the slaying by St Barry of a 'great serpent' in County Roscommon. The saint thrust his crozier at it before it disappeared into Lough Lagan, and where his knee touched the ground, a holy well, Tobar Barry, sprang up. Although the serpent may represent paganism, and the saint's victory is therefore the victory of Christianity over paganism, we cannot entirely ignore the possibility that some of the serpents in similar Irish tales may have been real water monsters, which are still seen from time to time in the lakes of Ireland and Scotland. These eerie, ugly monsters, with their aura of primeval mystery, appropriately symbolize the uncouth savagery which the Christians attributed to all non-Christian beliefs; but that is not to say that the monsters were totally symbolic and did not have a reality of their own.

" There is one element in Christianity which was not borrowed from Paganism -- religious intolerance. Referring to Buddhism, Confucianism, and Taoism, a writer on China says: 'Between the followers of the three national religions there is not only a total absence of persecution and bitter feeling, but a very great indifference as to which of them a man may belong.... Among the politer classes, when strangers meet, the question is asked: 'To what sublime religion do you belong,' and each one pronounces a eulogium, not on his own religion, but on that professed by the others, and concludes with the oft-repeated formula 'Religions are many; reason is one; we are all brothers.
