In Poland New Year's Eve is known as St Sylvester's Eve. This name according to legends arose from Pope Sylvester I, who was supposed to have imprisoned a dragon called Leviathan who was suppose to be able to escape on the first day of the year 1000, devour the land and the people, and was suppose to have set fire to the heavens. On New Year's Day, when the world did not come to an end, there was great rejoicing and from then on this day was called St Sylvester's Eve.
