Roman Architecture continued the legacy left by Greek architects and the established architectural orders, especially the Corinthian. However, the Romans were not content with simply emulating their predecessors. They were innovators who combined new construction techniques and materials with creative design to produce a whole range of brand new architectural structures. This article explores the fascinating world of Roman architecture, showcasing their innovative buildings and the materials and techniques they employed.

The Architectural Orders

Roman architects followed the guidelines established by the Greeks in terms of the architectural orders - Doric, Ionic, and Corinthian. The Corinthian order, in particular, was favored by the Romans and many of their buildings, even into Late Antiquity, had a distinct Greek influence. The Romans, however, added their own unique touch to the Corinthian capital, making it more decorative. They also enhanced the cornice, as can be seen in the Arch of Septimius Severus in Rome.

The Romans also introduced the composite capital, which combined the volute of the Ionic order with the acanthus leaves of the Corinthian. Another architectural adaptation was the Tuscan column, a form of the Doric column but with a smaller capital, slender shaft without flutes, and a molded base. The Romans also preferred monolithic columns, unlike the Greeks who used several drums stacked on top of each other.

Architectural Column Orders

Additionally, columns were often used for decorative purposes even when they were no longer structurally necessary. They were detached from the building yet remained attached to the façade at the base and entablature, or they became a part of the wall itself, functioning purely as decoration. This blending of architectural elements created a unique aesthetic that is distinctively Roman.

Materials & Techniques

Roman architects utilized various materials and techniques to bring their designs to life. Marble, particularly Carrara marble from Tuscany, was the stone of choice for state-funded projects. The Romans also imported marble from other parts of the empire, such as Parian marble from Paros and Pentelic marble from Athens. They favored colored varieties as well, including yellow Numidian marble, purple Phrygian marble, red porphyry from Egypt, and green-veined Carystian marble from Euboea.

Columns of Hagia Sophia

Another notable material used by the Romans was travertine white limestone, sourced from quarries near Tivoli. Its precise carving and inherent load-bearing strength made it an excellent substitute for marble. In addition to the use of stone, the Romans revolutionized the construction industry with their discovery of concrete. They realized that concrete could support significant weight and be used to create innovative architectural designs.

Concrete, known as opus caementicium, was made by mixing stone aggregate with lime mortar. It was laid thickly and provided a whole new range of construction possibilities. By incorporating volcanic sand, known as pozzolana, the Romans could create concrete that set under water and was even stronger than regular concrete. This technique allowed for the construction of large, soaring arches, column capitals, and sprawling domes.

Pantheon, Rome

To enhance the appearance of their structures, the Romans used stucco, marble veneer, and even brick or terracotta. Stucco, made from a mixture of sand, gypsum, and marble dust, could be carved and used to replicate architectural decorations typically rendered in stone. Brick, in particular, was a cost-effective alternative to stone and could be intricately carved to resemble architectural features.

Roman Architects: Masters of Construction

Although the credit for Roman buildings was often given to those who conceived and financed the projects, some architects did gain recognition for their work. Notable architects like Apollodorus of Damascus, who was responsible for Trajan's Forum and Baths in Rome, and Severus and Celer, who designed Nero's Golden House, left their mark on the architectural landscape.

Pont del Diable Aqueduct, Tarraco

Perhaps the most famous Roman architect is Vitruvius, whose work "On Architecture" has survived intact. Vitruvius covered all facets of architecture, providing advice for aspiring architects and capturing the essential ethos of Roman architecture: "All buildings must be executed in such a way as to take account of durability, utility, and beauty."

Key Roman Buildings: Icons of Roman Ingenuity

Roman architecture is renowned for its magnificent structures that have stood the test of time. Here are some key examples that showcase the creativity and innovation of Roman architects:

Aqueducts & Bridges: These impressive structures were designed to transport fresh water to urban centers from distant sources. The Pont du Gard near Nimes is a particularly awe-inspiring example.

Basilicas: Originally used as law courts, basilicas were large gathering places that often featured colonnades and were built along one side of the city's marketplace, or forum. The Severan Basilica at Lepcis Magna is a notable example.

Plan of the Baths of Diocletian

Baths: Roman baths were architectural wonders, known for their creative use of arches, domes, and vaults. The Baths of Caracalla in Rome exemplify the grandeur of these complexes.

Private Homes: Roman residences enchanted with their rich interior decoration, including frescoes and stucco. The House of the Vettii at Pompeii is a remarkable example.

Temples: Roman temples combined elements from Etruscan and Greek designs. The Maison Carrée at Nimes is a well-preserved exemplar.

Theatres & Amphitheatres: Roman theaters featured semicircular orchestras and highly decorative stage buildings. The Colosseum, with its awe-inspiring architecture, is the most famous amphitheater.

Triumphal Arches: Triumphal arches were monumental structures built to commemorate significant events. The Arch of Constantine in Rome is the largest surviving example.

Walls: Roman walls, which varied in width from thin to massive, were constructed using various techniques such as opus reticulatum and opus testaceum. They were often covered in plaster stucco for protection and decorative purposes.

Roman architecture, with its daring designs and innovative use of materials, left an indelible mark on the world of architecture. Their creations not only showcased their engineering prowess but also served as symbols of Roman power and cultural superiority. From their pioneering use of concrete to their intricate architectural details, Roman architecture continues to inspire and influence architectural styles to this day.
