Core Plot Summary
The story opens at King Arthur’s Christmas feast, where a mysterious giant green knight crashes the hall and challenges the court to a beheading game: one knight will strike him with an axe, then submit to a return blow in one year. Sir Gawain accepts, beheads the knight, who picks up his head and rides off, reminding Gawain of their pact. A year later, Gawain travels to the Green Chapel to fulfill his end. Along the way, he stays at a castle where the lord proposes a daily exchange: Gawain will give the lord any gifts he receives, and the lord will give Gawain his hunting spoils. Gawain hides a magical green girdle from the lord’s wife, which she claims will keep him safe. At the Green Chapel, the Green Knight (revealed as the castle lord in disguise) delivers three feigned blows, only nicking Gawain’s neck to punish him for hiding the girdle. Gawain returns to Camelot, where the court adopts the girdle as a symbol of humility and honor.
