Old Icelandic santa
Jólasveinn (santa) are figures from Icelandic folklore who in modern times have become the Icelandic version of Santa Claus. Their number has varied throughout the ages, but currently they are considered to be thirteen. They put rewards or punishments into shoes placed by children in window sills during the last thirteen nights before Christmas Eve. Every night, one jólasveinn visits each child, leaving gifts or rotting potatoes, depending on the child’s behavior throughout the year.
