Arthur is the legendary King of the Britons. The poet emphasizes the youthfulness of both the king and his courtiers, but there may be an element of criticism in this characterization, perhaps pointing to Arthur's immaturity. Arthur proves to be bolder and braver than his court when faced with the Green Knight's challenge. While his knights are silent, he steps forward and takes the axe, and he is prepared to chop off the Green Knight's head until Gawain asks to be given the task. Arthur is Gawain's uncle and Morgan's half-brother.
