Neoclassicism was an artistic style that emerged in the late 18th century as a reaction against the over-ornamentation of Rococo. Inspired by the clarity and restraint of ancient Greek and Roman art, Neoclassicism emphasized simplicity, order, and rationality. Key figures included the painters Jacques-Louis David and Jean-Auguste Dominique Ingres, the sculptor Antonio Canova, and the architects Robert Adam and Robert Smirke. Famous works from this period included David's painting The Oath of the Horatii, Canova's sculpture Psyche Revived by Cupid's Kiss, and buildings like the Madeleine Church in Paris.
