Epiphany (Twelfth Night) marks a visit to the baby Jesus by The Magi, (the three Kings, or Wise Men). The word 'Epiphany' comes from Greek and means 'manifestation'. It celebrates 'the revelation of God in his Son as human in Jesus Christ'.
In the West, Christians began celebrating the Epiphany in the 4th century, associating it with the visit of the Wise Men to Jesus.
According to the Gospel of Matthew, (Matthew 2:1-12) the three kings found baby Jesus by following a star across the desert to Bethlehem.
The three kings - named Melchior, Caspar and Balthazar - followed the star of Bethlehem to meet the baby Jesus. According to Matthew 2:11, they offered symbolic gifts of gold, frankincense and myrrh.
The gifts were symbolic of the importance of Jesus' birth, the gold representing his royal standing; frankincense his divine birth; and myrrh his mortality.
During the medieval period, Christmas was celebrated for the 12 days from Christmas Eve on December 24, until the Epiphany. Even up until the 19th century, January 6 was as big a celebration as Christmas Day.
