This is a visual evocation of the neoclassical period of art and architecture during the 18th and 19th century together with the influence of neoclassical forms in late 20th-century architecture and design. It deals with art, architecture, interiors, ornament and garden design. Originating in the discoveries of archaeologists at Pompeii and Herculaneum, neoclassicism swept Europe to influence the fine and decorative arts, introducing the styles of late Republican and early Imperial Rome. Crossing over into the world of political ideas, neoclassicism also became associated with revolutions in France and the United States of America. Painting, sculpture, architecture, interiors and the landscape garden all reflected neoclassical values and concerns. Today, in the 20th century, the influence of the neoclassical tradition still survives in architecture and decoration.
