Scientists say they have a bone from St Nicholas. He was a holy man who lived 1,600 years ago. He did many miracles, so the Christian church made him the saint of children. A scientist said: "We could…be looking at remains from St Nicholas." Stories that he secretly gave presents to children started today's Santa Claus story.

Santa Claus is also called Father Christmas. He brings presents to good children on Christmas Eve. Bad children get some coal. He delivers his presents on a sleigh pulled by flying reindeer. Santa is a fat, happy man with a white beard. He wears a red coat with a white collar. He has a toy-making workshop in the North Pole.
