The significance of Arthur's court in "Sir Gawain and the Green Knight " is seen from the beginning to the end of the story. Sir Gawain, a knight in King Arthur's court, represents the knightly code of honor. It is his duty to uphold the reputation of the court, as the court is known for holding the worthiest knights, where courage, honor, and loyalty shine. The beliefs and opinions of Arthur's court are tested but through Sir Gawain's valiancy and integrity, the reputation of the court is suppressed. .
It was Christmastime in Camelot, where all the good and great of the land gathered for the feast (lines 37-38). Among them is Sir Gawain, sitting at the dais and participating in the festival. During the celebration, the Green Knight suddenly arrives in all his magnificence and proposes a game to Arthur's court, a blow for a blow, also known as the "Beheading Game " (pg. 135). While everyone at court is in a state of shock, the Green Knight insults the knights and laughs at the king. After being insulted, King Arthur quickly accepts his proposal. As Sir Gawain is loyal to his king, he offers to take the king's place in the game and says, "I stake my claim. / May this melee be mine. / Should you call me, courteous lord " (lines 341-343). Making this statement, Sir Gawain is showing loyalty to his oath and to king Arthur. He is taking upon himself the duties of the king, asking that the job be given to him to slay the Green Knight once and for all. Only if the king accepts Sir Gawain's offer should he take his place in the game. One characteristic of Arthur's court is seen through Sir Gawain's loyalty to the king. He is given his place in the game to carry out the deed.
The rules of the game are repeated by Sir Gawain as he states, "I heave this axe, and whatever happens after, / in twelve month's time I'll be struck in return / with any weapon you wish, and by you and you / alone " (lines 382-385).
