Andrew Marvell uses hyperbole as well as the metaphysical conceit in his poem To His Coy Mistress.
A clear example of hyperbole, or exaggeration, are the following lines:
Love you ten years before the flood, (...)"
and
Thine eyes, and on thy forehead gaze; (...)"
what is exaggerated is the number of years
The hyperboles are:
Vaster than empires and more slow;
An hundred years should go to praise
Thine eyes, and on thy forehead gaze;
Two hundred to adore each breast,
But thirty thousand to the rest;
An age at least to every part,
The hyperboles serve to show how big the love for his mistress is, in putting it on measurable but impposible terms like vaster than empires or hundreds of years
