Mar 31 John Donne an English poet and a cleric in the Church of England. He is considered the pre-eminent representative of the metaphysical poets. His works are noted for their strong, sensual style and include sonnets, love poems, religious poems, Latin translations, epigrams, elegies, songs, satires and sermons. His poetry is noted for its vibrancy of language and inventiveness of metaphor, especially compared to that of his contemporaries. Donne's style is characterised by abrupt openings and various paradoxes, ironies and dislocations. These features, along with his frequent dramatic or everyday speech rhythms, his tense syntax and his tough eloquence, were both a reaction against the smoothness of conventional Elizabethan poetry and an adaptation into English of European baroque and mannerist techniques. His early career was marked by poetry that bore immense knowledge of English society and he met that knowledge with sharp criticism. Another important theme in Donne's poetry is the idea of true religion, something that he spent much time considering and about which he often theorized. He wrote secular poems as well as erotic and love poems. He is particularly famous for his mastery of metaphysical conceits
