John Donne was a leader of the Metaphysical poetry movement in 17th century England. This movement revolted against the outdated conventions of Elizabethan poetry, which had become artificial and lacked intellectual substance. As a Metaphysical poet, Donne wrote poems that were remarkable for their passionate intensity, intellectual complexity, and dramatic qualities. He drew on his own spiritual and romantic experiences. The Metaphysical poets, including Donne, Richard Crashaw, George Herbert, and Henry Vaughan, were known for their use of ingenious and unconventional conceits, arguments, and wit in their poetry.
