John Donne was an English POET, satirist, lawyer and cleric in the Church of England during the late 16th and early 17th centuries. He is best known for his metaphysical poetry, which explored themes of love, faith, and death. His most famous works include 'The Flea, ' 'A Valediction: Forbidding Mourning, ' and 'Death Be Not Proud.' He is also remembered for his rhyming couplets and his use of conceits.
