How does Jean de Joinville use imagery in Chronicles of the Crusades?

Examples of Imagery:

"At that moment the hearts of all those present, French and Venetians alike, were deeply moved, and many a tear was shed out of sympathy for this good and worthy man who would have had so much reason to remain behind. For he was very old, and although his eyes appeared bright and clear, he was none the less totally blind, having lost his sight through a wound in the hear. He was a man of great heart."

"Murzuphlus arrived without ceremony and with very few attendants, as he had been asked to do. As soon as he was in the house, Alexius drew him aside into a private room, where he had him flung to the ground and had his eyes torn out of his head. Judge for yourselves, after hearing of this treachery, whether people who could treat each other with such savage cruelty would be fit to hold lands or would deserve to lose them?"
