British faeries have a curious and contradictory relationship to humans’ ability to see them.
On the one hand, the faes are not infrequently associated with springs and wells that have the power of curing defects and diseases in human eyes. La Fontaine des Mittes on Jersey was one such: it cured both dumbness and sore eyes. This fountain is inhabited by two faeries (or nymphs), called Arna and Aiuna, whose presence perhaps is related to its curative properties. Compare, though, another Jersey site, Le Lavoir des Dames (fairies’ bathing place) off Sorrel Point. If you spied on the faes bathing there, they’d blind you. Readers may well be familiar with the fact that blinding (or striking dumb) are common punishments for violating faery privacy or glamour. The commonest victims are midwives who acquire- by accident- the ability to see through faery concealment whilst attending at a confinement. The midwives later see the faery father or some such person at a market- frequently stealing- and they are deprived of their (second) sight more or less violently. This may involve a breath or dust in the eye, a light touch or it may require physically and violently putting the eye out. A Guernsey woman who assisted at a fairy birth at the mound called Le Creux es Faies got baby spit in her eyes; fairy spit also subsequently stopped her seeing les p’tits gens ever again.
Other faery sites with healing powers include a well at Bugley in Wiltshire which relieved sore eyes, whilst the water of the Faeries’ Well near Blackpool treated weak eyes. Note that a mother who took some of this water to help her daughter’s failing vision tried it first on her own eyes before applying it to her child- for the entirely understandable maternal reason that she didn’t want to harm her child further. This accidentally and unintentionally bestowed the second sight upon her and for this abuse of the waters’ healing properties she was duly blinded by a fairy man at a market. In passing, we may speculate as to whether the daughter too gained the second sight- and why the faes seem not to have been so concerned about that risk. Perhaps where the water is applied as a cure, it has no ‘side-effects,’ perhaps (as is often said) children naturally have the second sight and can see the faeries anyway.
Lastly, elf arrows are said to be a good treatment for sore eyes and for this reason (as well as to protect themselves against elf assaults and to be able to cure their livestock) people would collect them.
In the Hertfordshire fairy-tale of the Green Lady, a poor girl finds employment as servant to a faery woman. One of her chores is fetching water from a well and the fish in that well warn her to neither eat the lady’s food nor to spy upon her. The girl ignores the second injunction and sees the woman dancing with a bogie. She’s found out and is blinded as a punishment, but the fairy well water restores her sight.
On the Isle of Man, a man who accidentally saw the fairies one night in a pea field near Jurby, witnessing a great crowd of little people dancing in red cloaks, was blinded for life by an old fairy woman who spotted him. Another, who spied on them when they were dancing by looking through the keyhole of a deserted cottage, was blinded with a poke from the bow of the fiddle for his impertinence. The Manx Little People will often expand their flocks by stealing sheep from humans. To do this, they use their glamour to make it impossible for a shepherd to accurately count the sheep he’s tending. The only remedy is for him to wash his eyes in running water first.
Scottish witch suspect John Stewart was rendered dumb- and blind in one eye- after the fairy king struck him with a white rod. This seems to have been a preliminary to teaching him some of the faeries’ secrets and magical knowledge. Perhaps we might say that some of his human senses were deliberately restricted before they were expanded by the acquisition of faery powers. Stewart’s sight and speech were restored in due course.
Our Good Neighbours can be highly touchy, though. A Victorian report from Wrexham tells of a fairy that blinded a person just because he looked at it. A very similar account comes from Exmoor: a person who ‘had dealings’ with the pixies later saw them thieving at the market in Minehead. When she protested, she was blinded. There is no mention of midwifery being involved, which may imply that her mere association with the fairies gave her the second sight.
