How does Chretien De Troyes use imagery in Arthurian Romances?

Much of the novel is concerned with describing the armor that individual knights wear and the locations to which they travel. Their chivalrous actions are described.

"Gawain saw that the ground had been much trampled by many horses and strewn with many fragments of shields and lances. There were clear signs that a pitched battle had been waged there between many knights; Gawain was bitterly disappointed not to have been present."
