The document discusses the Metaphysical poets, a school of poetry from the 17th century. It notes that John Donne is considered the founder of this school. The Metaphysical poets were known for using conceits and comparisons in their work, as well as allusions to various fields like science, mythology, and history. Their poetry was also characterized by the use of colloquial language and complex, obscure language and imagery. The document then analyzes two poems - John Donne's "Holy Sonnet VI" and Andrew Marvell's "To His Coy Mistress" - to illustrate themes and styles common in Metaphysical poetry.
