How does Francois Rabelais use imagery in Gargantua and Pantagruel?

Imagery:

"My Lord, without any doubt, he is trying to ape the language of the Parisians; yet all he can do is flay Latin alive. He thinks he is pindarizing; he believes he is a great orator in French because he despises the common spoken usage."

"Wait till this war is over, for you can never tell what problems may turn up, and war waged without a good supply of money has but one puff of vigour. Riches are the sinews of battle."
