|Fairies are small supernatural creatures of human form. They live in everyday surroundings. They are generally thought to be beneficial to humans. However, they are known to play pranks and it is best to treat them with respect. They are small, beautiful, airy, nearly transparent in body, and can assume any form. In Ireland fairies are called Sidhi, (pronounced "shee").
Fairies, as we know them today, are the ancient remnants of the Tuatha de Danaan, which means the people of the goddess Anu. Anu being like Mother Earth, the Tuatha were the gods and goddesses of the various aspects of nature. Like Nature itself, some were good and some were pretty frightening. With the onset of Christianity, these creatures, while still a rich part of Celtic myth and legend, grew considerably less forbidding and less powerful over the centuries becoming the whimsical, ethereal, airy, creatures we think of today.
