How does Olaudah Equiano use imagery in The Interesting Narrative and Other Writings?

Imagery:

"Our women too were, in my eyes at least, uncommonly graceful, alert, and modest to a degree of bashfulness; nor do I remember to have ever heard of an instance of incontinence amongst them before marriage. They are also remarkably cheerful. Indeed cheerfulness and affability are two of the leading characteristics of our nation."

"Let the polished and haughty European recollect that his ancestors were once, like the Africans, uncivilized, and even barbarous."
