Folklore fairies rarely had wings; the Victorians added them
The winged, tiny fairy of children's books is a late invention. In older European folklore fairies were human-sized or shape-shifting, flew by magic or rode on birds, got blamed for tuberculosis, and were warded off with church bells, inside-out clothes and four-leaf clovers.
The word itself carries a history. Fay comes through Old French from the Latin fata, a form of fatum, meaning fate, and first described a beautiful woman who could steer human affairs by magic. Fairy began as a collective noun, faerie, roughly the realm or company of fays, and only from the fourteenth century was it used for a single creature. People often avoided the word altogether, preferring careful nicknames such as the good folk, the wee folk or the people of peace.
There was never one origin story. Christian tradition cast fairies as angels demoted during a heavenly revolt, caught between paradise and hell when the gates shut. Others saw them as the dead, as an older race of humans, or as nature spirits and pagan gods who lingered in reduced form after Christianity spread. Some historians, including Barthelemy d'Herbelot, traced them to the winged peris of Persian myth. In the seventeenth century, especially as Puritanism grew in England, fairies were often lumped with demons, and dealing with them could be punished as witchcraft; King James I described them in his Daemonologie as illusory spirits serving sorcerers.
Appearance varied widely. Accounts range from tiny beings to human-sized ones, and small size could be a disguise rather than a fixed trait. On Orkney they were short, dressed in dark grey and sometimes armoured. Wings, now standard, are rare in folklore and became common only in Victorian and later art; modern illustrators favour butterfly or dragonfly wings.
The Victorian and Edwardian craze shrank fairies into nursery figures and, through the Celtic Revival, made them part of Irish heritage. Scholars such as Carole Silver link the fascination to anxiety about industrialisation and vanishing folk customs. Even Arthur Conan Doyle wrote a 1922 book on the subject.
