The poets represented here cover a good selection of this Elizabethan style. (Elizabeth herself is represented by a verse). Gardner has wisely chosen the poets and their poems. Have this volume if only to read the verse of Donne and Marvell, heck, if only to read "The Sonne Rising" and "To My Coy Mistress". Certainly this would be an excellent place to start in a study of the metaphysical poets.
Her style at times leans towards the metaphysical itself: 'A brief comparison can be a conceit if two things patently unlike, or which we should never think of together, are shown to be alike in a single point in such a way, or in such a context, that we feel their incongruity'. So to help understand the poetry we have an introduction that is partly written in a 'stong lines' style and which needs almost the same amount of concentration as the poetry.
There is a bit of literary name dropping: 'Between Dryden and Johnson comes Pope, who is reported by Spence to have remarked that "Cowley, as well as Davenant, borrowed his metaphysical style from Donne"'.
The spellings have not been modernised which may be a problem.
Overall recommened strongly.
