"To His Coy Mistress" by Andrew Marvell is an unnamed man's proposal to his coy mistress to sleep with him. When the mistress does not give in to the lover's persuasive pleas while playing to her romantic sensibilities, he attempts to frighten her with the reality of the nearness of death. The lover uses this theme of carpe diem in his argument by trying to convince his lover to be with him by telling her of what little time they have, and because of this scarcity of time, they must be together now while they have the chance to. In other words they must "seize the day" while they still have time.
In the first stanza of the poem the male speaker begins his seduction by telling her of all the wonderful things they could do if only they had enough time. He ironically gives them impossibly long stretches of time in which they have to spend together, "I would love you ten years before the flood, and as you should, if you please, refuse till the conversion of the Jews," he proclaims. He then speaks of how his "vegetable love" would grow slowly with time and how he would use this infinite amount of time that they have to treasure her and shower her with beautiful compliments. He explains to her that she deserves nothing but the best and assures her that if they had the time, he would have courted her and done all of these wonderful, romantic things, but unfortunately they do not.
The lover then abruptly pulls his mistress out of this romantic world of ever lasting love and beautiful compliments and takes her to the "deserts of vast eternity" where the mistress's beauty and therefore appeal is all lost. His desperation increases as he pleads for his lover to understand that death is oh so near! "But at my back I always hear Time's winged chariot hurrying near," he shows her the bleak reality that is the fleetingness of life. He attempts to scare her by describing disturbing images of worms attempting to steal the lifeless body of the mistress's "long preserved virginity.
