Père Fouettard
The Père Fouettard (French pronunciation: [pɛʁ fwetaʁ]) (French for Father Whipper) is a character who accompanies St. Nicholas in his rounds during St. Nicholas' Day (6 December) dispensing lumps of coal and/or floggings to the naughty children while St. Nick gives gifts to the well behaved. He is known mainly in the far north and eastern regions of France and in the south of Belgium, although similar characters exist all over Europe (see Companions of Saint Nicholas). This "Whipping Father" was said to bring a whip with him to spank all of the naughty kids who misbehaved.
Origin
The most popular story about the origin of Le Père Fouettard was first told in the year 1150. An innkeeper (or in other versions a butcher) captures three boys who appear to be wealthy and on their way to enroll in a religious boarding school. Along with his wife, he kills the children in order to rob them. One gruesome version tells that they drug the children, slit their throats, cut them into pieces, and stew them in a barrel. St. Nicholas discovers the crime and resurrects the children. After this, Le Père Fouettard repents and becomes St. Nick's partner. A slightly altered version of this story claims that St. Nicholas forced Le Père Fouettard to become his assistant as a punishment for his crimes.
