Happy Twelfth Night to everybody!
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 can be traced to pre-Christian European festivals such as the Celtic festival of Samhain and the Ancient Roman festival of Saturnalia.
In some countries, and in the Catholic religion worldwide, the Twelfth Night and Epiphany marks the start of the Carnival season, which lasts through Mardi Gras Day.
