Sir Gawain and the Green Knight is a story from the Arthurian legend which was originally a published poem written in the 14th century. It tells the tale of the Green Knight who comes to King Arthur’s castle and challenges a knight to deliver one blow and that blow will be returned one year later. Sir Gawain takes the challenge and cuts the head off the Green Knight but the knight doesn’t die. He instructs Sir Gawain that he will deliver the same blow, which puts Gawain on a quest. The story teaches about honour and keeping of one’s word.
