How does Robert Greene use imagery in The Art of Seduction?

Imagery:

"So while the chaperone knitted away, the duke initiated her into the rituals of libertinage," Book 1, Chapter 2: The Rake, p. 20.

"D'Annunzio would craft slogans for the audience to repeat, or would ask emotionally loaded questions for them to answer. He flattered the crowd, made them feel they were part of some drama. Everything was vague and suggestive," Book 1, Chapter 2: The Rake, p. 23.
