The Welsh tradition of the The Mari Lwyd was a custom performed during winter celebrations around the dates of Christmas and New Year. A horse-figure, that in the past was often made from a horses skull, was mounted upon a pole. Which was carried by a person hidden under a cloth from door to door. Accompanied by a group of singers the Mari Lwyd knocks on the door and the first verse of a traditional song is sung. This would in turn be answered in song by the person in the house. After a number of verses had been exchanged, the Mari Lwyd singers would then be invited into the house and provided with food and drink before leaving with a farewell song.
This tradition continues in parts of South Wales. The history of the custom is a matter of debate. However, many believe it to be pre-Christian in origin although often later adapted to fit in with the stories related to the new faith.
