How does the mystical number three present itself within the story "Sir Gawain and Green Knight"?Please help me answer this question...

The number three is very important in the prose work "Sir
Gawain and the Green Knight".

The first time the number
three appears in the text as Gawain is leaving Arthur's castle to keep his promise to
the Green Knight. Gawain crosses himself three times and asks Christ to give him
speed.

The second appearance of the number three appears
when Gawain is speaking of how long he has been traveling to find the chapel of the
Green Knight.

In the third appearance of the number three,
Sir Gawain has arrived at Lord Bertalik's castle and they have made a promise to each
other to give to each whatever they receive during the day. The trumpets blow three
times signalling the beginning of the first day's hunt.

The
fourth appearance of the number three comes, again, during another hunt day. Three of
Bertalik's men throw themselves onto a boar to submit him.  The boar is too strong and
the men fail.

The fifth reference to the number three,
again, is during another hunt. This time Bertalik and his men are pursuing a fox. The
reference to three is that the fox was being threatened "threefold" by the men and
elements around him.

The sixth and seventh references to
the number three is spoken of when Lady Bertalik gives Gawain three kisses and Gawain,
then in turn, gives the three kisses to Lord
Bertalik.

Overall, the number three is used, as was typical
in Medieval literature, to provide symmetry to the text. The collections of threes which
exist are also important:

-Lady Bertalik goes to see Gawain
on three separate occasions.

-Lord Bertalik goes hunting on
three seperate days.

-Lady Bertalik kisses Gawain three
seperate times.

-Gawain swings the axe upon the Green
Knight three times.
