Billy Blind, Billy Blin, Billy Blynde, Billie Blin, or Belly Blin is an English and Lowland Scottish household spirit, much like a brownie. It appears, however, only in ballads, where it frequently advises the characters. It is probable that the character of Billy Blind is a folk memory of the god Woden or Odin from Germanic mythology, in his "more playful aspect" and the character seems to have been the same character as that of Blind Harie, the "blind man of the game" in Scotland.
In Child Ballad no 6, Willie's Lady, Willie's wife has been in labour and can not deliver because Willie's mother, a rank witch, is preventing her. Billy Blind advises Willie to make a wax figure of a baby and invite his mother to the christening. In her rage, the mother demands to know how all her magic was undone, listing all the things she's done, and Willie is able to undo them.
