The Sidhe, or spirit race, called also the Feadh-Ree or fairies, are supposed to have been once angels in heaven, who were cast38 out by Divine command as a punishment for their inordinate pride.

Some fell to earth, and dwelt there, long before man was created, as the first gods of the earth. Others fell into the sea, and they built themselves beautiful fairy palaces of crystal and pearl underneath the waves; but on moonlight nights they often come up on the land, riding their white horses, and they hold revels with their fairy kindred of the earth, who live in the clefts of the hills, and they dance together on the greensward under the ancient trees, and drink nectar from the cups of the flowers, which is the fairy wine.

Other fairies, however, are demoniacal, and given to evil and malicious deeds; for when cast out of heaven they fell into hell, and there the devil holds them under his rule, and sends them forth as he wills upon missions of evil to tempt the souls of men downward by the false glitter of sin and pleasure.

They can also assume all forms, and will never know death until the last day comes, when their doom is to vanish away—to be annihilated for ever. But they are very jealous of the human race who are so tall and strong, and to whom has been promised immortality. And they are often tempted by the beauty of a mortal woman and greatly desire to have her as a wife.

The children of such marriages have a strange mystic nature, and generally become famous in music and song. But they are passionate, revengeful, and not easy to live with. Every one knows them to be of the Sidhe or spirit race, by their beautiful eyes and their............
