Roman Art and the Evolution of Early Christian Architecture

Realism and Idealism in Roman Sculpture

Roman portraiture includes both bust sculptures and historical equestrian relief sculptures. These reliefs are prominently featured on commemorative monuments, altars, triumphal arches, and columns.

The Rise of Christianity

Half a century after the spread of Christianity throughout the Roman Empire, Emperor Constantine granted religious freedom to Christians via the Edict of Milan in 313 AD. By 380 AD, the Edict of Thessalonica declared Christianity the official religion of the empire.

Architecture for Worship Services

Following the Roman model, the first major basilicas were built in Rome, such as Saint John Lateran and St. Peter's Basilica. These structures defined the guidelines for Christian architecture until the 19th century.

• Interior Layout: The building maintains a rectangular shape divided into 3 to 5 naves.
• Transept: A nave added across the space above the apse, with arms protruding from the main body of the building.
• Roofing: Instead of traditional Roman barrel vaults, wooden roofs were used, often hidden by smooth coffered ceilings.
• Entrance: The entrance is preceded by an arcaded courtyard or atrium, followed by a narthex (vestibule) where catechumens—those not yet baptized—would gather.

Baptisteries and Mausoleums

Early Christian builders also adopted circular forms for baptisteries and mausoleums, typically featuring a baptismal font at the center.

Christianization of Classical Imagery

The process of Christianization involved adopting classical figures to represent Christ, often modeled after figures like Apollo or the moschophoros. While wall painting declined in basilicas, rich mosaics began to appear on walls, vaults, and floors.

New Artistic Characteristics

• Spirituality: Creation of an atmosphere of spirituality through monochromatic backgrounds.
• Hierarchical Importance: Figures are depicted in different sizes to signify symbolic importance.
• Stylization: Faces lack individualization, marking Rome's transition into a new world.

Glossary

• Vault: A roof structure based on a semicircular arch.
