Epiphany is a Christian feast celebrating the ‘shining forth’ or revelation of God to mankind in human form, in the person of Jesus Christ.
The observance had its origins in the eastern Christian churches, and included the birth of Jesus Christ; the visit of the three Magi (Caspar, Melchior and Balthasar) who arrived in Bethlehem; and all of Jesus’ childhood events, up to his baptism in the Jordan by John the Baptist. The feast was initially based on (and viewed as a fulfillment of) the Jewish Feast of Lights. This was fixed on January 6.
The first reference to Epiphany in the Latin West is a slighting remark by Clement of Alexandria in Stromateis, I, xxi, 45: “There are those, too, who over-curiously assign to the Birth of Our Saviour not only its year but its day…” Origen’s list of festivals (in Contra Celsus, VIII, xxii) omits any reference to Epiphany. The first reference to an ecclesiastical feast of the Epiphany, in Ammianus Marcellinus (XXI:ii), is in 361.
Thus in the Latin church, the feast of Christmas was established before that of Epiphany. Over time the western churches decided to celebrate Christmas on December 25. The eastern churches continued to treat January 6 as the day marking Jesus’s birth. This has given rise in the west to the notion of a twelve day festival, starting on December 25, and ending on January 6, called the twelve days of Christmas, although some Christian cultures — especially those of Latin America — extend it to 40 days, ending on Candlemas, or February 2 (known as Candelaria in Spanish).

Food and drink are the center 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.
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.
