For several weeks, Gawain traverses a cold and mysterious landscape, then comes upon a grand castle. It is coming to be Christmas time and he is hospitably invited into this great castle where he is encouraged to join the celebration. He is treated to every possible consideration. The lord of the castle proposes that someone devise a Christmas game.
Gawain says he would love to join in the merriment of the games, but that he is honor-bound to go to the Green Chapel by New Year’s. The lord of the castle tells him not to worry, the chapel is very nearby, and then he introduces the game. Each day, the lord will go hunting while Gawain stays in the castle. At the end of each day, they will exchange what each has caught. The lord of the castle goes hunting, of course, and catches various prey. Gawain, meanwhile, is in the castle, where he is subjected to the amorous advances of the lady of the castle. Gawain courteously refuses the lady, but each day, they exchange a kiss. Rather comically, at the end of each day, the lord of the castle comes back and hands over to Gawain his prey from that day’s hunt, and Gawain kisses the lord of the castle.
On the third day, the lady of the castle gives Gawain a green sash that will allegedly protect him from any evil or misfortune. When the lord returns, Gawain decides not to hand over the sash. The next day, Gawain gets directions to the Green Chapel. He takes his leave, and he goes on to acquit himself of his debt.
