" The lover's soul breathes through her body with "instant fires." This is not literal fire on her skin, but it's rather used to describe how the feeling of lustful desire is like heat. In line 26, "marble vault" is being used as a euphemism to describe the death of his beautiful lady and her grave; however, he does this in a decent and indirect manner. .
In line 31," the grave's a fine and private place," he uses euphemism to describe privacy and loneliness of the marble vault, which he mentioned earlier in line 26. In line 44, "iron gates of life" is a metaphor used to describe all the obstructions and circumstances beyond his control that are blocking his ambitions of making his way through her heart. .
The similes used in "To His Coy Mistress" include line 34 "Sits on thy skin like morning dew," where he makes a comparison between the lady's youthful hue and the morning dew. Line 38 "like amorous birds of prey," Marvell describes their symbiotic and playful co-existence like amorous birds of prey. .
The hyperbole (exaggeration) used by the character to exaggerate his feelings and emotions can be found in line 8 "Love you ten years before the flood." Obviously, the character was not born during Noah's time. And this can be considered as one of his luring techniques to get the coy mistress. Hyperbolism found from line 10 to 18, "Till the conversion of the Jews." describes the length of time he would allow their love to develop. This biblical reference gives an impression that the Jews did not want to be converted by Jesus Christ. Likewise, a comparison is being made in this line to exaggerate his unchanging love for the mistress." "My vegetable love should grow" "Vaster than empires, and more slow;" exaggerates how much love he would develop for the lady over time.
