The fairies of Shakespeare's plays are not typical of the fairies of early modern belief. While the fairies in Shakespeare's most famous play, A Midsummer Night's Dream, are portrayed as relatively benign, and ultimately good, the fairies of early modern England were almost universally viewed as evil spirits. The darker opinion of fairies in early modern England is attested to in a variety of sources, including literary, religious, legal, and contemporary works of scholarship. The early modern English material on fairies establishes two things: first, that fairies were considered real, in the sense that they were believed to be real beings who really inhabited the English countryside, and second, that they were pernicious.
In A Discourse Concerning Devils and Spirits, first appearing in print as an appendix to the 1665 edition of Scot's Discovery of Witchcraft, the anonymous author discusses the abodes of fairies and like creatures:
Subordinate unto these of the Air, are the Terrestrial Spirits, which are of several degrees according to the places which they occupy, as Woods, Mountains, Caves, Fens, Mines, Ruins, Desolate Places, and Ancient Buildings, called by the Ancient Heathens after various names, as Nymphs, Satyrs, Lamii, Dryades, Sylvanes, Cobali … And more particularly Faeries …
All of these locales are places that would be found in the countryside, and all are the sorts of ordinary places that English villagers would be familiar with in their area.
