When looking for interpretations of literature, one needs to look for the images, symbols, and themes associated with the story in hand. For "Sir Gawain and the Green Knight," there are many images and symbols that one can draw upon to help with understanding the text. An obvious image is that of the color green which represents life and youth. It is one of the images that can explain why the Green Knight is able to walk out of King Arthur's hall without a head but still living; this episode suggests that he is the epitome of life and regeneration! He tests Gawain's character through the charade they play; and, this places him in higher authority than Gawain, and possibly even Arthur, because he teaches life's lessons through risky challenges. If the Green Knight is the teacher, then Gawain must be the student who must learn a very important life lesson about truth, honesty, and courage. For more tips, check out the links below.
