The early modern fairies do not have any single origin, representing a conflation of disparate elements of folk belief, influenced by literature and speculation. Their origins are less clear in the folklore, being variously dead, or some form of demon, or a species completely independent of humans or angels. The folkloristic or mythological elements combine Celtic, Germanic and Greco-Roman elements. Folklorists have suggested that their actual origin lies in religious beliefs that lost currency with the advent of Christianity. These explanations are not necessarily incompatible, and they may be traceable to multiple sources.
