“There Is a Polish Story of a Witch Who Made a Girdle of Human Skin”

From Sabine Baring-Gould’s indispensable work Curious Myths of the Middle Ages (1866):

There is a Polish story of a witch who made a girdle of human skin and laid it across the threshold of a door where a marriage-feast was being held. On the bridal pair stepping across the girdle they were transformed into wolves. Three years after the witch sought them out, and cast over them dresses of fur with the hair turned outward, whereupon they recovered their human forms, but, unfortunately, the dress cast over the bridegroom was too scanty, and did not extend over his tail, so that, when he was restored to his former condition, he retained his lupine caudal appendage, and this became hereditary in his family; so that all Poles with tails are lineal descendants of the ancestor to whom this little misfortune happened.
