How does Ovid use imagery in The Erotic Poems?

Imagery:

"Every lover's on active service, my friend, active service, believe me and Cupid has his headquarters in the field. Fighting and love-making belong to the same age-group—in bed as in war, old men are out of place. A commander looks to his troops for gallant conduct, a mistress expects no less," p. 100.

"Love was better than doing nothing. That's how Cupid slips in; that's how he stays," p. 244.
