Twelfth Night is a festival ... marking the coming of the Epiphany.

The Epiphany traditionally being celebrated on the 6th by certain in the West.

In Western Church traditions the Twelfth Night concludes the Twelve Days of Christmas

Bruce Forbes wrote that " "In 567 the Council of Tours proclaimed that the entire period between Christmas and Epiphany should be considered part of the celebration, creating what became known as the twelve days of Christmas, or what the English called Christmastide. On the last of the twelve days, called Twelfth Night, various cultures developed a wide range of additional special festivities. The variation extends even to the issue of how to count the days. If Christmas Day is the first of the twelve days, then Twelfth Night would be on January 5, the eve of Epiphany. If December 26, the day after Christmas, is the first day, then Twelfth Night falls on January 6, the evening of Epiphany itself."[5]

Origins and history

In medieval and Tudor England, the Twelfth Night marked the end of a winter festival that started on All Hallows Eve — now more commonly known as Halloween. The Lord of Misrule symbolizes the world turning upside down. On this day the King and all those who were high would become the peasants and vice versa. At the beginning of the Twelfth Night festival, a cake that contained a bean was eaten. The person who found the bean would rule the feast. Midnight signaled the end of his rule and the world would return to normal. The common theme was that the normal order of things was reversed. This Lord of Misrule tradition dates back to pre-Christian European festivals such as the Celtic festival of Samhain and the Ancient Roman festival of Saturnalia.[7]

Traditions

Food and drink are the centre of the celebrations in modern times, and all of the most traditional ones go back many centuries. The punch called wassail is consumed especially on Twelfth Night, but throughout Christmas time, especially in the UK. Around the world, special pastries, such as the tortell and king cake are baked on Twelfth Night, and eaten the following day for the Feast of the Epiphany celebrations. In English and French custom, the Twelfth-cake was baked to contain a bean and a pea, so that those who received the slices containing them should be designated king and queen of the night's festivities.[8]

In Ireland, it is still the tradition to place the statues of the Three Kings in the crib on Twelfth Night or, at the latest, the following Day Little Christmas.

In colonial America, a Christmas wreath was always left up on the front door of each home, and when taken down at the end of the Twelve Days of Christmas, any edible portions would be consumed with the other foods of the feast. The same held true in the 19th-20th centuries with fruits adorning Christmas trees. Fresh fruits were hard to come by, and were therefore considered fine and proper gifts and decorations for the tree, wreaths, and home. Again, the tree would be taken down on Twelfth Night, and such fruits, along with nuts and other local produce used, would then be consumed.
