How does Michel de Montaigne use imagery in Complete Works: Essays, Travel Journal, Letters?

Imagery:

"Urbino, sixteen miles, a town of little distinction, on the top of a mountain of medium height, but lying in all directions according to the slopes of the place, so that there is nothing level about it, and everywhere you have to go up and down. The market was being held, for it was Saturday."

"He kept a tighter rein on his soldiers, and drew them up shorter, when they were near the enemy."
