Père Fouettard (pronounced [pɛʁ fwɛtaʁ]; French for "Father Whipper" or "Old Man Whipper") is a character who accompanies St. Nicholas on his rounds during St. Nicholas' Day (6 December) dispensing lumps of coal and/or beatings to naughty children while St. Nicholas gives gifts to the well behaved. He is known mainly in the far north and eastern regions of France, in the south of Belgium, and in French-speaking Switzerland, 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 children who misbehaved.
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. Nicholas' partner. A slightly different version of this story claims that St. Nicholas forced Le Père Fouettard to become his assistant as a punishment for his crimes.
Another story states that during the Siege of Metz (a city in Eastern France) in 1552, an effigy of king Charles V was burned and dragged through the city. Meanwhile, an association of tanners created a grotesque character (also a tanner) armed with a whip and bound in chains who punished children. After Metz was liberated, the charred effigy of Charles V and the character created by the tanners somehow assimilated into what is now known as Le Père Fouettard. Events surrounding the city's liberation and the burning of the effigy coincided with the passage of St. Nicholas, hence Le Père Fouettard became his "bad cop" counterpart.
In the 1930s, Le Père Fouettard appeared in the United States under the translated name Father Flog or Spanky. Although almost identical to the original French personification, Father Flog had nothing to do with Christmas and also had a female accomplice named Mother Flog. The two doled out specific punishments for specific childhood crimes (e.g. cutting out the tongue for lying).
The most common depiction of Le Père Fouettard is of a man with a sinister face dressed in dark robes with scraggly unkempt hair and a long beard. He is armed with a whip, a large stick, or bundles of switches. Some incarnations of the character have him wearing a wicker backpack in which children can be placed and carried away. Sometimes he merely carries a large bundle of sticks on his back. Often, his face is darkened to varying degrees. Some say it is because of his being born of a burned effigy, others say that it is from the soot in the chimneys that he goes down with St. Nicholas. In other representations, Le Père Fouettard is identical to the Dutch character Zwarte Piet (Black Peter). Further renderings of the character show him as being nearly identical to Saint Nicholas or Santa Claus, but wearing a black suit.
