John Donne was a 17th century English poet known as one of the Metaphysical Poets. He reacted against the sweet tones of 16th century verse and adopted a more energetic, witty, and inventive style that fused rationality with passion. His poems sought to imitate human speech patterns, giving them a realistic and intimate feel. Donne often used metaphors and conceits that creatively extended comparisons over entire poems, drawing from academia like astronomy, metallurgy, and physiology. His poems sometimes involved paradoxes that expressed the contradictory nature of human behavior or arguments designed to tease the recipient.
