Neoclassicism refers to a period in the late 17th and 18th centuries that drew inspiration from the intellectual and structural ideals of classical antiquity. It had three stages: the Restoration period, the Augustan age, and the age of Johnson. Famous poets of this era included John Milton, John Dryden, Alexander Pope, and Samuel Johnson. Neoclassical poetry was characterized by rationalism, scholarly allusions, didacticism, realism, and adherence to classical rules rather than passion or emotion. It often employed heroic couplets and poetic diction.
