The Welsh tradition of the the Mari Lwyd is a custom performed during winter celebrations around the dates of Christmas and New Year. Although performed over the Christmas period, the Mari Lwyd is thought to be a pre-Christian tradition believed to bring good luck. The strange and frightening horse-figure, that in the past was often made from a horses skull, but now mostly artificial, was mounted upon a pole. Which was carried by a person hidden under a cloth, which had ribbons attached, from door to door.
