An appearance, or a becoming manifest.
A church festival celebrated on the 6th of January, the twelfth day after Christmas, in commemoration of the visit of the Magi of the East to Bethlehem, to see and worship the child Jesus; or, as others maintain, to commemorate the appearance of the star to the Magi, symbolizing the manifestation of Christ to the Gentles; Twelfthtide.
Literally, an unveiling, a revelation. The name of the festival held on January 6, celebrating the visit of the Magi to the infant Jesus, and symbolizing the revelation of Christ to the Gentiles, and by extension to all the nations. The name is also applied to the liturgical season extending from January 6 up to Ash Wednesday.
