As with painting, Neoclassicism made its way into sculpture in the second half of the 18th century. In addition to the ideals of the Enlightenment, the excavations of the ruins at Pompeii began to spark a renewed interest in classical culture. Whereas Rococo sculpture consisted of small-scale asymmetrical objects focusing on themes of love and gaiety, neoclassical sculpture assumed life-size to monumental scale and focused on themes of heroism, patriotism, and virtue.

In his tomb sculpture, the Enlightenment philosophe Voltaire is honored in true Neoclassical form. In a style influenced by ancient Roman verism, he appears as an elderly man to honor his wisdom. He wears a contemporary commoner’s blouse to convey his humbleness, and his robe assumes the appearance of an ancient Roman toga from a distance. Like his ancient predecessors, his facial expression and his body language suggest an air of scholarly seriousness.

Neoclassical sculptors benefited from an abundance of ancient models, albeit Roman copies of Greek bronzes in most cases. The leading Neoclassical sculptors enjoyed much acclaim during their lifetimes. One of them was Jean-Antoine Houdon, whose work was mainly portraits, very often as busts, which do not sacrifice a strong impression of the sitter’s personality to idealism. His style became more classical as his long career continued, and represents a rather smooth progression from Rococo charm to classical dignity. Unlike some Neoclassical sculptors he did not insist on his sitters wearing Roman dress, or being unclothed. He portrayed most of the great figures of the Enlightenment, and traveled to America to produce a statue of George Washington, as well as busts of Thomas Jefferson, Benjamin Franklin, and other luminaries of the new republic. His portrait bust of Washington depicts the first President of the United States as a stern, yet competent leader, with the influence of Roman verism evident in his wrinkled forehead, receding hairline, and double chin.

The Italian artist Antonio Canova and the Danish artist Bertel Thorvaldsen were both based in Rome, and as well as portraits produced many ambitious life-size figures and groups. Both represented the strongly idealizing tendency in Neoclassical sculpture.

Canova has a lightness and grace, where Thorvaldsen is more severe. The difference is exemplified in Canova’s Hebe (1800–05), whose contrapposto almost mimics lively dance steps as she prepares to pour nectar and ambrosia from a small amphora into a chalice, and Thorvaldsen’s Monument to Copernicus (1822-30), whose subject sits upright with a compass and armillary sphere.

Neoclassical Architecture

Neoclassical architecture, which began in the mid-18th century, looks to the classical past of the Graeco-Roman era, the Renaissance, and classicized Baroque to convey a new era based on Enlightenment principles. This movement manifested in its details as a reaction against the Rococo style of naturalistic ornament, and in its architectural formulas as an outgrowth of some classicizing features of Late Baroque. In its purest form, Neoclassicism is a style principally derived from the architecture of Classical Greece and Rome. In form, Neoclassical architecture emphasizes the wall and maintains separate identities to each of its parts.

The first phase of Neoclassicism in France is expressed in the Louis XVI style of architects like Ange-Jacques Gabriel (Petit Trianon, 1762–68). Ange-Jacques Gabriel was the Premier Architecte at Versailles, and his Neoclassical designs for the royal palace dominated mid 18th century French architecture.

After the French Revolution, the second phase of Neoclassicism was expressed in the late 18th century Directoire style. The Directoire style reflected the Revolutionary belief in the values of republican Rome. This style was a period in the decorative arts, fashion, and especially furniture design, concurrent with the post-Revolution French Directoire (November 2, 1795–November 10, 1799). The style uses Neoclassical architectural forms, minimal carving, planar expanses of highly grained veneers, and applied decorative painting. The Directoire style was primarily established by the architects and designers Charles Percier (1764–1838) and Pierre-François-Léonard Fontaine (1762–1853), who collaborated on the Arc de Triomphe in Paris, which is considered emblematic of French neoclassical architecture.

Though Neoclassical architecture employs the same classical vocabulary as Late Baroque architecture, it tends to emphasize its planar qualities rather than its sculptural volumes. Projections, recessions, and their effects on light and shade are more flat. Sculptural bas-reliefs are flatter and tend to be framed in friezes, tablets, or panels. Its clearly articulated individual features are isolated rather than interpenetrating, autonomous, and complete in themselves.

Even sacred architecture was classicized during the Neoclassical period. The Panthéon, located in the Latin Quarter of Paris, was originally built as a church dedicated to St. Geneviève and to house the reliquary châsse containing her relics. However, during the French Revolution, the Panthéon was secularized and became the resting place of Enlightenment icons such as Voltaire and Jean-Jacques Rousseau. Designer Jacques-Germain Soufflot had the intention of combining the lightness and brightness of the Gothic cathedral with classical principles, but its role as a mausoleum required the great Gothic windows to be blocked. In 1780, Soufflot died and was replaced by his student, Jean-Baptiste Rondelet.

Similar to a Roman temple, the Panthéon is entered through a portico that consists of three rows of columns (in this case, Corinthian) topped by a Classical pediment. In a fashion more closely related to ancient Greece, the pediment is adorned with reliefs throughout the triangular space. Beneath the pediment, the inscription on the entablature translates as: “To the great men, the grateful homeland.” The dome, on the other hand, is more influenced by Renaissance and Baroque predecessors, such as St. Peter’s in Rome and St. Paul’s in London.

Intellectually, Neoclassicism was symptomatic of a desire to return to the perceived “purity” of the arts of Rome. The movement was also inspired by a more vague perception (“ideal”) of Ancient Greek arts and, to a lesser extent, 16th century Renaissance Classicism, which was also a source for academic Late Baroque architecture. There is an anti-Rococo strain that can be detected in some European architecture of the earlier 18th century. This strain is most vividly represented in the Palladian architecture of Georgian Britain and Ireland.

The trend toward the classical is also recognizable in the classicizing vein of Late Baroque architecture in Paris. It is a robust architecture of self-restraint, academically selective now of “the best” Roman models. These models were increasingly available for close study through the medium of architectural engravings of measured drawings of surviving Roman architecture.

French Neoclassicism continued to be a major force in academic art through the 19th century and beyond—a constant antithesis to Romanticism or Gothic revivals.
