In Elizabethan England, Jan. 5 was celebrated as Twelfth Night, the Eve of Epiphany, with bonfires of seasonal evergreens. That's the origin of the title of William Shakespeare's play, “Twelfth Night.”
The Shakespearean play that refers to the date of epiphany is called Twelfth Night. The play revolves around the mistaken identities of Sebastian and Viola, who both end up falling in love with the wrong people. The date of epiphany is significant in the play because it marks the end of the festive season and the beginning of a new year.
