Once denounced as a demon by the Orthodox church, Morozko brings presents to good children, and is often accompanied by a snow maiden
Grandfather Frost, Ded Moroz, or Morozko is a seasonal character from Slavic folklore easily mistaken for Saint Nicholas or Father Christmas. He has a long white beard, wears a full-length red or blue coat and hat, and brings presents to good children. He is sometimes accompanied by his granddaughter, Snegurochka the snow maiden, who is made of snow.
But Grandfather Frost is a pre-Christian spirit, once denounced as demonic by the Orthodox church. His character also encompasses the darker side of winter.
