Krampus is a horned, demon-type creature, sometimes depicted as half man half goat. His name means “claw” and he’s possibly based on mythological creatures such as the satyrs.
Mostly known in Austria and Bavaria, he said to visit on 5th December, the day before St Nicholas. He carries a chain or a birch stick to wave around, and his job is to remind the naughty children to be good.
According to some stories he leaves lumps of coal for the children who haven’t been well behaved but in others he goes as far as carrying them off to eat!
