Chaucer's poetry was a new kind-he adapted European literary techniques to the English language and came up with a revolutionary new poetic style for the language. However, in other parts of the country, there were poets who were still using the alliterative techniques of Old English. One such poet wrote "Sir Gawain and the Green Knight", the tale of Sir Gawain's courageous rise to the Green Knght's challenge. Sir Gawain was one of King Arthur's Knights of the Round Table.
In this poem we see head-rhyme and the four strong beats of Old English poetry:
"On the ground the Green Knight graciously stood,
With his head slightly slanting to expose the flesh."
And we see some of the violent imagery that we saw in "Beowulf":
"And slashed swiftly down on the exposed part,
So that the sharp blade sheared through, shattering the bones,"
and
"The fair head fell from the neck, struck the floor,
And people spurned it as it rolled around.
Blood spurted from the body, bright against the green."
Some say that the Green Knight represents the old Celtic pagan religion (remember, King Arthur is a Celtic legend; Beowulf is a Scandinavian legend); while King Arthur and his knights represent Christianity. Thus, in this tale the old beliefs are challenging the new, but the new prevail. The "green man" is a common image in Celtic mythology.
REMEMBER: The word "romance" in medieval literature is different to the modern meaning. Romance means adventure, rising to challenges, and eventually earning the love of a lady.
