Greek sculpture evolved over three main periods from the archaic to the classical and Hellenistic eras. In the archaic period, sculptures like kouroi and korai were rigid and geometric. The classical period saw a focus on idealized human beauty and proportions under artists like Polykleitos, Phidias, and Praxiteles. Finally, Hellenistic sculpture moved towards realism, emotion, and a variety of subjects influenced by the wider Hellenistic world.
