In Norse tradition, fairies
are believed to descend from the small, dark Neolithic people
who escaped to remote areas from Iron Age invaders. Here they
carried on their agriculture and hunter/gatherer way of life
from their earth homes, using their flint-tipped arrows and flint
spears and knives.
They carried with them the tradition of
worshipping the Goddess and, because they became so elusive,
tales grew up of their fairy kingdom and powers of invisibility.
These peoples became known as 'The Little People', the fairies,
and their reaction to the sword-wielding invaders is reflected
in their legendary fear of metal, especially iron.
The deities of the Old Ways were also translated
into fairies. The Goddess survived in myth and secret worship
as the Good Fairy, the Fairy Godmother, or Queen of the Fairies,
Titania (as described in Shakespeare's 'A Midsummer Night's Dream').
The Horned God became the Fairy King, Oberon.
