Across Alpine Europe during the Christmas season, men and women adorn themselves in devil horns and carry pitchforks, hellbent on scaring children into behaving. Welcome to Krampusnacht.

Krampus, in Tyrol also called Tuifl, is a demon-like creature represented by a fearsome, hand-carved wooden mask with animal horns, a suit made from sheep or goat skin and large cow bells attached to the waist that the wearer rings by running or shaking his hips up and down. (Getty Images)

Krampus has been a part of Central European, alpine folklore going back at least a millennium, and since the 17th-century Krampus traditionally accompanies St. Nicholas and angels on the evening of December 5 to visit households to reward children that have been good while reprimanding those who have not.
