When dealing with 17th-century poetry, it may be helpful to classify poets as cavalier or metaphysical poets, as this distinction often appears on the GRE literature. According to The Columbia Electronic Encyclopedia:
“The foremost poets of the Jacobean era, Ben Jonson and John Donne, are regarded as the originators of two diverse poetic traditions—the Cavalier and the metaphysical.”
A brief comparison of these authors will give you a pretty good idea of their divergent styles. While Johnson’s poetry is generally light or humorous in style, secular in subject, and often deals with love or sexuality, Donne’s is characterized by subtle argumentations and “metaphysical conceits,” often dealing with the soul or religion. Several metaphysical poets, especially John Donne, were influenced by NeoPlatonism. One of the primary Platonic concepts found in metaphysical poetry is the idea that the perfection of beauty in the beloved acted as a remembrance of perfect beauty in the eternal realm. (See John Donne – A Valediction Forbidden Mourning).
