How does Jeanette Winterson use imagery in Sexing the Cherry?

Imagery:

"I fell in love once, if love be that cruelty which takes us straight to the gates of Paradise only to remind us they are closed for ever."

"The earth is round and flat at the same time. This is obvious. That it is round appears indisputable; that it is flat is our common experience, also indisputable. The globe does not supersede the map; the map does not distort the globe."
