Fairies have long been with us – in our imaginations, at least. But for many hundreds of years, they were not necessarily tiny and fey, but grotesque or fierce elemental forces, capable of great darkness. "In 1800, if you thought your child was a fairy it would have been like demonic possession – you would have put that child in the fire to drive out the fairy," points out Alice Sage, a curator and historian.
