     One of the traditions which is now a necessary part of Christmas is that of Father Christmas, or Santa

Claus. According to the modem 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 moming. 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. 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 chimneys of their houses. 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, or becomes 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 let them onto 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.
