Joan the Wad
Joan the Wad is a mythological character in Cornish folklore. She is the Queen of the Pixies, which are tiny mythical creatures usually associated with the counties of Cornwall and Devon in England.
Wad is an Eastern Cornwall colloquial term for torch or bundle of straw.
Folklore
Joan the Wad has been associated with Jack o' the Lantern, the King of the Pixies. The two may also be considered will-o'-the-wisp type characters who lead travellers astray on lonely moors, hence the rhyme:Jack-the-lantern, Joan-the-wad,
That tickled the maid and made her mad,
Light me home, the weather's bad.
However, Joan is also thought to use her Wad to light the way to safety and good luck, as another rhyme says, "Good fortune will nod, if you carry upon you Joan the Wad".
