Read it through once

Finally, Marvell's chief contribution to English poetry may be described as this synthesis of clarity, wit, and moral irony. He anticipated in many ways the later emphasis upon precision and restraint. His influence is not dramatic or obvious; it works by example, by the demonstration that poetic greatness can consist in the perfection of tone and the economy of expression. To read Marvell is to learn the art of saying much in little, of keeping the mind alive to the complexity of experience while preserving the music and immediacy of feeling.
