Scientists say they have a bone from Santa Claus. His real name is St Nicholas. He was a holy man who lived in the 4th century. Many stories say he did many miracles, so the Christian church made him a saint – the saint of children. A scientist said: "This bone…suggests that we could possibly be looking at remains from St Nicholas." There are stories that he secretly gave presents to poor people. This is the story behind today's Santa Claus.

Santa Claus is also called Father Christmas. He brings presents to well-behaved children on Christmas Eve. Badly-behaved children get some coal. He delivers his presents on a sleigh. The sleigh is pulled through the air by flying reindeer. Santa Claus is a fat, happy man with a white beard. He wears a red coat with a white collar, red trousers, a black belt and black boots. He lives in the North Pole and has a toy-making workshop there.
