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. .Lewis Spence

It must not be thought, however, that in pagan Ireland Fairyland was altogether conceived as a Hades or place of the dead. We have already seen that in some of its types and aspects it was inherently nothing of the sort; as when, for example, it came to be confused with the Land of the Gods. In all likelihood these separate paradises and deadlands of a nature so various were the result of the stratified beliefs of successive races dwelling in the same region. A conquering race would scarcely credit that its heroes would, after death, betake themselves to the deadland of the beaten and enslaved aborigines. The gods of vanquished races might be conceived as presiding over spheres of the dead for which their victors would have nothing but contempt, and which, because of that very contempt, might come to be conceived as hells or places of a debased and grovelling kind, pestiferous regions which only the spirits of despised "natives" or the undesirable might inhabit.Lewis Spence

Here it is necessary briefly to consider the question of the cult of ancestors before venturing farther. The spirits of the departed are believed to be possessed of supernatural powers which they did not enjoy in the flesh. They may also be dissatisfied or malignant in consequence of being suddenly deprived of life, and if they are neglected by the living, are apt to be revengeful. Therefore they must be cajoled and propitiated. Fear of beings belonging to a mysterious state or sphere of which he knew nothing continually haunted and terrified primitive man and induced in him what is known as" the dread of the sacred." It was every man's personal duty to attend to the demands or requirements of his deceased ancestors. At first he would succour his own immediate forebears with food and gifts; but it must have been borne in upon him that when his parents joined the great majority, the care of the spirits of their parents likewise devolved upon him.. and, by degrees, he might even come to regard himself as responsible for the well-being of a line of spirit ancestors of quite formidable genealogy. These, through his neglect, might starve in their tombs; or, alternatively, they might crave his company. Because of vengeance or loneliness they might send disease upon him, for the savage almost invariably believes illness to be brought about by the action of jealous or neglected ancestors. The loneliness of the spirit-world is the dead man's greatest excuse for desiring the company of his descendants. .Lewis Spence

But I find it necessary to repeat in this particular place that the division into classes, which is so salient a part of modern demonology, had, and has, little significance for primitive man or for the peasant in a comparatively low state of mental development. To such people, spirits of all kinds - fairies, the ghosts of the dead, and even witches and water-kelpies - are all creatures of the supernatural class between which he scarcely differentiates.Lewis Spence

At Bealltainn, or May Day, every effort was made to scare away the fairies, who were particularly dreaded at this season. In the West Highlands charms were used to avert their influence. In the Isle of Man the gorse was set alight to keep them at a distance. In some parts of Ireland the house was sprinkled with holy water to ward off fairy influence. These are only a mere handful out of the large number of references available, but they seem to me to reveal an effort to avoid the attentions of discredited deities on occasions of festival once sacred to them. The gods duly return at the appointed season, but instead of being received with adoration, they are rebuffed by the descendants of their former worshippers, who have embraced a faith which regards them as demons. In like manner the fairies in Ireland were chased away from the midsummer bonfires by casting fire at them. At the first approach of summer, the fairy folk of Scotland were wont to hold a "Rade, " or ceremonial ride on horseback, when they were liable to tread down the growing grain.Lewis Spence

It must be understood that in some cases the process by which a god or goddess degenerates into a fairy may occupy centuries, and that in the passage of generations such an alteration may be brought about in appearance and traits as to make it seem impossible that any relationship actually exists between the old form and the new. This may be accounted for by the circumstance that in gradually assuming the traits of fairyhood the god or goddess may also have taken on the characteristics of fairies which Already existed in the minds of the folk, the elves of a past age, who were already elves at a period when he or she still flourished in the full vigour of godhead. For in one sense Faerie represents a species of limbo, a great abyss of traditional material, into which every kind of ancient belief came to be cast as the acceptance of one new faith after another dictated the abandonment of forms and ideas unacceptable to its doctrines. The difference between god and fairy is indeed the difference between religion and folk-lore. .Lewis Spence

As Mr. R. U. Sayee has well said: 'It should be clear a priori that fairy lore must have developed as a result of modifications and accretions received in different countries and at many periods, though we must not overlook the part played by tradition in providing a mould that to some extent determines the nature of later additions.' It must also be self-evident that a great deal of confusion has been caused by the assumption that some spirit-types were fairies which in a more definite sense are certainly not of elfin provenance. In some epochs, indeed, Faerie appears to have been regarded as a species of limbo to which all 'pagan' spirits - to say nothing of defeated gods, monsters, and demons - could be banished, along with the personnel of Olympus and the rout of witchcraft. Such types, however, are usually fairly easy of detection.Lewis Spence
