Refers to the ancient Greek period, culture, and art of ancient Greece that lasted from about 330 BCE to 31 BCE, when Augustus defeated Cleopatra and Mark Antony. It is characterized by an international culture that was ushered in by Alexander the Great's conquest of India, Egypt, and the Near East. In architecture and art, the style is marked by greater sophistication, complexity, and diversity than was known in earlier Greek styles. Architecture diverges from strict rules of earlier periods. Sculptors emphasized more realistic figures in a greater variety of poses than in earlier Greek art.
