In Spain Christmas celebrations continue until the 6th of January (Epiphany or Twelfth Night which marks the end of the winter celebrations that start on All Hallows Eve. In mediaeval times this was a time when the Lord of Misrule ruled symbolising the World turning upside down as all of the Lords of the land would become peasants and vice versa). On this day, DÃa de los Reyes Magos, children receive presents from the Wise Men (named in tradition as Melchor, Gaspar and Balthasar) to whom they have written letters in the days leading up to this date. These letters are either given to the wise men’s ‘emissaries’ and royal postmen in the town squares of their homes a few days before or to the Wise Men themselves as they parade through their town on the 5th of January.
