Marvell's a worthy successor of Donne's to the post of Lord Wit, as exemplified in the former's poems about love, gardens and metaphysics. Like Donne, Marvell could write with a pen both learned and beautiful, but he also had a more florid style than his predecessor, which helps him occasionally to soar aloft. Finally, to round off the parallels, M. was a stickler for couplets, meaning that neither poet's ambitions lay in rhyme nor stanza form.
However, Marvell would take his metaphors much further than Donne, and showcased his learning with more vim, as showcased by such whoppers as "An Horatian Ode", the two poems dedicated to Cromwell and the two Painter poems. These works are riddled with allusions, without any sacrifice of the poetic effect. Granted, for me personally, it isn't always very interesting to read such context-dependent poems, especially of politicians, but the way Marvell pulls it off is really admirable.
In fact, my main complaint is not about Marvell but about this edition. It has no footnotes or explanatory notes whatsoever. How is one supposed to get a grasp of especially the poems under the title "Of Public Affairs" without copious notes to elucidate the copious references that Marvell is barraging at the reader? While the notes would definitely mar the initial reading experience due to the constant necessity to interrupt the flow, they would be better in the long run to gain proper appreciation of Marvell's talent. There were also a couple of times, when certain obsolete word choices would have warranted an explanation, though for the most part the verbiage is pretty understandable for anyone already familiar with the language of the times, and I must say I am somewhat glad that Everyman has retained the original spelling and not saturated the text with needless definitions.
As for Marvell's style, I can't say that I think his rhythm to be that impeccable. He constantly favours the couplets, which can give his longer poems a rather jejune air, and when these are delivered in a somewhat uneven rhythm, it can make the reading somewhat cumbersome in the long run.
But for the most part, it was apparent that Marvell has a great command of the nuances of the language and a keen mind to boot. I would not have minded if the compilation had focused more on the more general topics such as love and death and kept the political poems to a minimum, but at least one was given a proper idea of the scope of the poet's genius.
