Final answer:
Andrew Marvell and John Donne are best classified as Metaphysical Poets, known for their clever and complex language, metaphysical conceits, and intellectual explorations in their poetry.
Step-by-step explanation:
Andrew Marvell and John Donne are both examples of Metaphysical Poets. This group of 17th-century poets are known for their witty and complex poetry that employs ironic contrasts, paradoxes, and philosophical inquiries. Their work is often characterized by the use of metaphysical conceits—unusually imaginative analogies or metaphors—where an extended comparison might compare, for instance, the soul to a drop of dew, or love to a physical object like a compass. They were not Romantic Poets, Imagists, or Modernist Poets; rather, they belonged to an earlier tradition that differed significantly in style and themes from these later movements. While Romantic poets like Wordsworth and Shelley celebrated nature and emotions, and Modernist poets like Ezra Pound and Marianne Moore experimented with forms and language, Metaphysical poets focused on intellectual play and a witty display of emotion.
