“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.” MythologyFairyGodsFolkloreFairies Book:British Fairy Origins Source: British Fairy Origins
“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.” FairyHalloweenGodsDemonsSpiritsSamhainBeltaneFaires Book:British Fairy Origins Source: British Fairy Origins
