Santa Claus
Santa Claus, also known as Saint Nicholas, Kris Kringle, Father Christmas, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December). The modern Santa Claus grew out of traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas and the Dutch figure of "Sinterklaas" (himself also based on Saint Nicholas). Some maintain Santa Claus also absorbed elements of the Germanic god Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky.
Santa Claus
Santa Claus appears in the weeks before Christmas in department stores or shopping malls, or at parties. The practice of this has been credited to James Edgar, as he started doing this in 1890 in his Brockton, Massachusetts department store. He is played by an actor, usually helped by other actors (often mall employees) dressed as elves or other creatures of folklore associated with Santa. Santa's function is either to promote the store's image by distributing small gifts to children, or to provide a seasonal experience to children by listening to their wishlist while having them sit on his knee (a practice now under review by some organisations in Britain, and Switzerland). Sometimes a photograph of the child and Santa are taken. Having a Santa set up to take pictures with children is a ritual that dates back at least to 1918.
