“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.”

“This brings me to the question of the antiquity of the belief in fairies and to the associated problem of the existence of strata or stages in fairy belief. The antiquity of the belief is revealed by the wide distribution of tales concerning fairies, while it is also indicated by the antipathy of the elves to iron and salt - ancient taboos both. Not only so, but many traits respecting fairies, especially shape-shifting and the belief in their semi-corporeal state, are eloquent of primitive notions. That the process of the fairy belief witnessed more than one stage of development in the course of successive ages appears more than probable. 'The fairies of one race,' remarks Wentz, 'are the people of the preceding race.' If this statement lacks a certain precision, one realizes the implication; that is, that the ghosts or gods of a preceding race may come to be regarded by their successors as fairies.”

“There may be fairies, there may be elves, but God helps those who help themselves.”

“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.”

“(...) Some fairy lore makes a clear division between good and wicked types of fairies — between those who are friendly to mankind, and those who seek to cause us harm. In Scottish tales, good fairies make up the Seelie Court, which means the Blessed Court, while bad fairies congregate in the Unseelie Court, ruled by the dark queen Nicnivin. In old Norse myth, the Liosálfar (Light Elves) are regal, compassionate creatures who live in the sky in the realm of Alfheim, while the Döckálfar (the Dark Elves) live underground and are greatly feared. Yet in other traditions, a fairy can be good or bad, depending on the circumstance or on the fairy's whim. They are often portrayed as amoral beings, rather than as immoral ones, who simply have little comprehension of human notions of right and wrong.The great English folklorist Katherine Briggs tended to avoid the "good" and "bad" division, preferring the categorizations of Solitary and Trooping Fairies instead. (...)”

“All three of the English types I have mentioned can, I think, be accounted for as the results of the presence of different cultures, existing side by side in the country, and who were the creation of the folk in ages distantly removed one from another. In a word, they represent specific " strata" of folk-imagination. The most diminutive of all are very probably to be associated with a New Stone Age conception of spirits which haunted burial-mounds and rude stone monuments. We find such tiny spirits haunting the great stone circles of Brittany. The "Small People," or diminutive fairies of Cornwall, says Hunt, are believed to be "the spirits of people who inhabited Cornwall many thousands of years ago. "The spriggans, of the same area, are a minute and hirsute family of fairies" found only about the cairns, cromlechs, barrows, or detached stones, with which it is unlucky to meddle." Of these, the tiny fairies of Shakespeare, Drayton, and the Elizabethans appear to me to be the later representatives. The latter are certainly not the creation of seventeenth-century poets, as has been stated, but of the aboriginal folk of Britain.”
