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.
Mrs. Claus
Since 1889, Mrs. Claus has been generally depicted in media as a fairly heavy-set, kindly, white-haired elderly female baking cookies somewhere in the background of the Santa Claus mythos. She sometimes assists in toy production, and oversees Santa's elves. It is worth noting that, when not portrayed as white-haired or elderly, she is often shown to have red hair. This could be because red hair is the color that most commonly fades to white with age. She is usually depicted wearing a fur dress of red or green.
