W. Y. Evans-Wentz,
The Fairy-Faith in Celtic Countries
“ In religions, mythologies, and the Fairy-Faith, too, we behold the attempts which have been made by different peoples in different ages to explain in terms of human experience this unseen world, its inhabitants, its laws, and man’s relation to it. The Ancients called its inhabitants gods, genii, daemons, and shades; Christianity knows them as angels, saints, demons, and souls of the dead; to uncivilized tribes they are gods, demons, and spirits of ancestors; and the Celts think of them as gods, and as fairies of many kinds. ”
