[3] Jacob Grimm (Deutsche Mythologie) traces the threatening or scary companions of Saint Nicholas (such as the Krampus of the Austro-Bavarian dialect region) to Christianized versions of household spirits (kobolds, elves).
This association took place mainly in the territories of the Holy Roman Empire, including German-speaking Europe, the Low Countries, the Czech lands, Hungary and Slovakia.
In Italy, for example, there are Babbo Natale ("Father Christmas", a local version of Santa Claus) and the Befana, a witch-like old lady that rides a broomstick and brings candies on Epiphany's eve.
In some areas of Northern Italy (Bergamo, Brescia, Cremona, Lodi, Mantova, Parma, Piacenza, Reggio Emilia, Verona, Trento, Udine) there is Santa Lucia, a veiled blind old woman who on December 13 brings gifts to children, riding a donkey that tows a cart, accompanied by her helper Castaldo or Castaldòn.
In other areas there is Gesù bambino ("Child Jesus"), and in many parts of Switzerland and northeastern Italy (east of the Piave river), Saint Nicholas is also celebrated on December 6.
