One of the traditions which is now a necessary part of Christmas is that of Father Christmas, or Santa Claus. According to the modern legend, he is a magical figure who visits all the children of the world during the night before Christmas Day, leaving presents which they find the next morning. He flies through the night sky in a sledge pulled by reindeer, and enters houses by climbing down chimneys. This strange legend is based on the life of a man called Nicholas, but in fact we know very little about him. Historians think he was a Christian bishop(主教) in Turkey in about 285-350 A. D. One of the stories about him is that he helped three poor girls. No one would marry them because they were so poor. To provide them with money for their weddings, Nicholas secretly dropped some gold coins down the chimney of their house. After Nicholas died, he was made a saint(圣人) by the church. (The name Santa Claus thus comes from St Nicholas.) His feast day was celebrated in December, and parents started giving their children secret presents from St Nicholas. Over the years, this custom became part of our Christmas traditions.
Recently, a psychologist has claimed that Father Christmas is “the perfect fantasy” for children. According to Professor Anthony Clare, children love the character of Father Christmas because he is like an ideal father: he loves children and gives them presents, but he never criticizes them, is never angry, and children do not even need to thank him for the presents. Other writers, however, point out that Father Christmas can be a frightening character to some children. Jane Bidder says that some children are terrified of this fat, bearded old man. It can certainly confuse many children. As parents, we warn our children to be careful of strangers and never to let them into the house, and yet we tell children that a strange man will come into their bedroom at night! Some children can become very worried about this idea and fear that he is a kind of burglar.
Most children, however, understand from their parents and from the media that Father Christmas is basically a benign character, and look forward to his annual visit with joy and excitement.
