Problem:Passage: In Camelot on New Year's Day, King Arthur's court is exchanging gifts and waiting for the feasting to start when the king asks first to see or hear of an exciting adventure. A gigantic figure, entirely green in appearance and riding a green horse, rides unexpectedly into the hall. He wears no armour but bears an axe in one hand and a holly bough in the other. Refusing to fight anyone there on the grounds that they are all too weak to take him on, he insists he has come for a friendly "Christmas game": someone is to strike him once with his axe on condition that the Green Knight may return the blow in a year and a day. The splendid axe will belong to whoever takes him on. Arthur himself is prepared to accept the challenge when it appears no other knight will dare, but Sir Gawain, youngest of Arthur's knights and his nephew, begs for the honour instead. The giant bends and bares his neck before him and Gawain neatly beheads him in one stroke. However, the Green Knight neither falls nor falters, but instead reaches out, picks up his severed head and remounts, holding up his bleeding head to Queen Guinevere while its writhing lips remind Gawain that the two must meet again at the Green Chapel. He then rides away. Gawain and Arthur admire the axe, hang it up as a trophy and encourage Guinevere to treat the whole matter lightly.
