John Donne (1572-1631) is a poet of concerted emotional and intellectual force, whose strenuously original approach to the subject matter, diction and form of verse re-made English poetry. Donne’s poetry combines paradoxical wit, scientific and theological learning with the rhythms and diction of spoken language. Crises of love, conscience, and faith are the great concerns of his poetry which is by turns exalted or disenchanted, direct or oblique, morally profound or outrageously spiteful.
