The fae relationship with the humble and everyday candle is rather more complex and magical than we might initially imagine. Four examples illustrate different aspects of this.
Fae beings are sometimes compared to candles- that is, when they appear in the form of points of light and especially when seen as the will of the wisp– looking like a lantern to lead travellers astray. In such a form they have often been compared explicitly to candle flames . In the form of the canwyll corph (corpse candle) in Wales, they appear to predict an imminent death. For both phenomena, see c.12 of my Beyond Faery (2020).
Faeries also make normal everyday use of the light that candles provide- for example, the lhiannan shee of the Isle of Man performs the role of a washer woman akin to the bean nighe of the Scottish Highlands. She will be seen at night, washing clothes in a river by the light of a taper. Perhaps, too, just like humans, faeries can be comforted by the homely light. At Manor Farm, East Halton, in Lincolnshire, the resident hob was something of a nuisance, because he could use his great strength for pranks as well as undertaking chores. The residents of the farm were said to leave a candle lit in a window every night ‘to keep the Hob quiet.’
Candles have more magical properties, though. In County Durham, there was once a great fear of pregnant women and unbaptised babies being stolen by the ever watchful faeries (as nurse maids and as changelings), so the practice was to leave a candle burning all night in the same room as the cradle. Some explanation of the reasoning behind this might come from an incident reported on the Isle of Man. A confined mother was being watched over at night by two women. They kept feeling drowsy and, as soon they started to fall asleep, the candle in the room would dim. The pair would then awaken with a start, brought on by their fear of the little folk, and the flame would flare up again. This happened several times until they awoke to find the expectant mother out of bed and an argument taking place outside. The fairies had been in the act of taking her but the women’s waking had disturbed and defeated them. These examples suggest that candle light can have some power to dispel faery power, or to keep them at bay, and it may in fact be this that was being exploited against the hob on Manor Farm.
In Arkengarthdale in North Yorkshire, a man laid a bogle in his cottage by opening his bible, lighting a candle and then pronouncing the injunction “Now then, you can read, or dance, or die as you like.” The bogle was observed to vanish in the form of a grey cat and wasn’t seen again for many years. However- as is often the case- the banishment was not permanent. One day the man met the bogle again on the stairs of his house- and this spelled his doom. Shortly after the encounter he left home to go to his work in a local mine, and died in an accident. This use of the candle as part of the exorcism ceremony may have simply relied upon the precedent of church practices, of course, but the flame might also have had special properties against the bogle.
A poor widow from Reeth (the neighbouring parish to Arkengarthdale) suffered inconvenience and loss when her neighbour stole some candles from her. The thief soon found himself haunted by a bogle; he tried shooting it but it had no body that could be wounded (of course). The next day it came to him, warning “I’m neither bone nor flesh nor blood, thou canst not harm me. Give back the candles, but I must take something from thee.” It plucked an eyelash, which may seem harmless enough, except that his eye ‘twinkled’ for ever after that day. The protection given to the poor woman may indicate faery morality, but perhaps the particular concern over candles suggests an extra, magical dimension to the story.
Lastly, we have a record of magical candles being used by Scottish faeries. A man’s wife was abducted into the faery hill at Pollochaig in Inverness-shire. Another local man had been given some enchanted wax candles by the sith folk, the sort they use to light their nocturnal dances (although more poetic and romantic accounts of such festivities tend to describe them using glow-worms for illumination) . This favoured individual lent the husband one but warned that the Good Neighbours would use tricks to try to steal it back and defeat him. Just as predicted, the husband lost the candle. He borrowed one after another, making repeated (failed) attempts to enter the sithean until he finally succeeded and got his wife back, but- sadly- by this point all those magical candles had been used up.
To sum up, the faery interaction with candles seem to be threefold. They can use them for conventional lighting purposes but tapers may also be used magically, both against the faes and by them. The exact significance of this is still hard to determine: our limited folklore evidence illustrates the situations but doesn’t presently provide quite enough detail for us to really understand the dynamics.
