‘Faerie itself may perhaps most nearly be translated by Magic — but it is magic of a peculiar mood and power, at the furthest pole from the vulgar devices of the laborious, scientific, magician.’
- J. R. R. Tolkien, On Fairy-Stories
The Green children of Woolpit
Wikipedia Green children of Woolpit
After learning to speak English, the children—Ralph says just the surviving girl—explained that they came from a land where the sun never shone and the light was like twilight. William says the girl called their home St Martin's Land; Ralph adds that everything there was green. According to William, the children were unable to account for their arrival in Woolpit; they had been herding their father's cattle when they heard a loud noise (according to William, it was like the sound of the bells of Bury St Edmunds Abbey[11]) and suddenly found themselves by the wolf pit where they were found. Ralph says that they had become lost when they followed the cattle into a cave and, after being guided by the sound of bells, eventually emerged into our land.
