Theory One:
Faeries were originally worshiped as minor goddesses, such as nymphs or tree spirits. In alchemy they were regarded as elementals. With the coming of Christianity, the church decreed them to be evil beings and they were marginalized.
Theory Two:
Faeries were a folkloric belief concerning the dead. Ghosts and faeries have similar legends; the burial mounds of the Tír na nÓg, the danger of eating food in the Realm of Fae or Hades, and both the dead and faeries living underground.
Theory Three:
Faeries were a class of demoted angels. One story states that when the angels revolted, God ordered the gates shut; those still in heaven remained angels, those in hell became demons, and those caught in between became faeries.
Theory Four:
Faeries were an intelligent species, distinct from humans and angels. The Celts describe a race of diminutive people who had been driven into hiding by invading humans. They came to be seen as spirits and believed to still exist in the Otherworld.
Some believe faeries still exist in one form or another--a race of beings, spirits of the dead, or descendants of fallen angels. Others believe they are nothing but folklore and myth. What do you think?
