The meaning of the host’s wife’s girdle changes over the course of the narrative. It is made out of green silk and embroidered with gold thread, colors that link it to the Green Knight. She claims it possesses the power to keep its wearer from harm, but we find out in Part 4 that the girdle has no magical properties. After the Green Knight reveals his identity as the host, Gawain curses the girdle as representing cowardice and an excessive love of mortal life. He wears it from then on as a badge of his sinfulness. To show their support, Arthur and his followers wear green silk baldrics that look just like Gawain’s girdle.
The Colour green
The mysterious, gigantic man who interrupts the feast at Arthur’s court on New Year’s Eve is green from the top of his head to the tips of his toes. We can use other things we know about the Green Knight to figure out what the symbolism of the color might be. For example, instead of carrying traditional knightly weapons, he carries a holly branch in one hand and a large axe in the other. Both of these objects connect him to nature, particularly the woods. The Green Knight’s test of Gawain makes him very aware of his strong survival instinct, something he shares with animals. And the place where Gawain must meet the Green Knight – the Green Chapel – is one of the most wild, natural places in the poem. Based on these clues, we’re pretty sure that the color green represents nature. People, places, and things in the poem that are green somehow have a significant connection to nature.
