Roman architecture in the context of "Trajan's Bridge"

De architectura (On architecture, published as Ten Books on Architecture) is a treatise on architecture written by the Roman architect and military engineer Marcus Vitruvius Pollio and dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first known book on architectural theory, as well as a major source on the canon of classical architecture.

It contains a variety of information on Greek and Roman buildings, as well as prescriptions for the planning and design of military camps, cities, and structures both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). Since Vitruvius wrote early in the Roman architectural revolution that saw the full development of cross vaulting, domes, concrete, and other innovations associated with Imperial Roman architecture, his ten books give little information on these distinctive innovations of Roman building design and technology.

The art of Ancient Rome, and the territories of its Republic and later Empire, includes architecture, painting, sculpture and mosaic work. Luxury objects in metal-work, gem engraving, ivory carvings, and glass are sometimes considered to be minor forms of Roman art, although they were not considered as such at the time. Sculpture was perhaps considered as the highest form of art by Romans, but figure painting was also highly regarded. A very large body of sculpture has survived from about the 1st century BC onward, though very little from before, but very little painting remains, and probably nothing that a contemporary would have considered to be of the highest quality.

Ancient Roman pottery was not a luxury product, but a vast production of "fine wares" in terra sigillata were decorated with reliefs that reflected the latest taste, and provided a large group in society with stylish objects at what was evidently an affordable price. Roman coins were an important means of propaganda, and have survived in enormous numbers.

Ancient Greek art is the visual and applied arts, as well as the architecture, produced by the Hellenes or Greek peoples from the start of the Iron Age to the Hellenistic period, ending with Roman conquest of Greece at the Battle of Corinth in 146 BCE. It stands out among that of other ancient cultures for its development of naturalistic but idealized depictions of the human body, in which largely nude male figures were generally the focus of innovation. The rate of stylistic development between about 750 and 300 BC was remarkable by ancient standards, and in surviving works is best seen in sculpture. There were important innovations in painting, which have to be essentially reconstructed due to the lack of original survivals of quality, other than the distinct field of painted pottery.

Greek architecture, technically very simple, established a harmonious style with numerous detailed conventions that were largely adopted by Roman architecture and are still followed in some modern buildings. It used a vocabulary of ornament that was shared with pottery, metalwork and other media, and had an enormous influence on Eurasian art, especially after Buddhism carried it beyond the expanded Greek world created by Alexander the Great. The social context of Greek art included radical political developments and a great increase in prosperity; the equally impressive Greek achievements in philosophy, literature and other fields are well known.

Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire, usually dated from AD 330, when Constantine the Great established a new Roman capital in Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. There was initially no hard line between the Byzantine and Roman Empires, and early Byzantine architecture is stylistically and structurally indistinguishable from late Roman architecture. The style continued to be based on arches, vaults and domes, often on a large scale. Wall mosaics with gold background became standard for the grandest buildings, with frescos a cheaper alternative.

The richest interiors were finished with thin plates of marble or coloured and patterned stone. Some of the columns were also made of marble. Other widely used materials were bricks and stone. Mosaics made of stone or glass tesserae were also elements of interior architecture. Precious wood furniture, like beds, chairs, stools, tables, bookshelves and silver or golden cups with beautiful reliefs, decorated Byzantine interiors.

The Roman architectural revolution, also known as the concrete revolution, is the name sometimes given to the widespread use in Roman architecture of the previously little-used architectural forms of the arch, vault, and dome. For the first time in Europe, possibly in the world (earlier experiments with arches in Ancient Egypt and Mesopotamia notwithstanding), the potential of these elements was fully appreciated and exploited in the construction of a wide range of civil engineering structures, public buildings, and military facilities. Throughout the Roman Empire, from Syria to Scotland, engineers erected structures using semicircular arches. The first use of arches was for civic structures, like drains and city gates. Later the arches were utilized for major civic buildings bridges and aqueducts, with the outstanding 1st century AD examples provided by the Colosseum, Pont Du Gard, and the aqueduct of Segovia. The introduction of the ceremonial triumphal arch dates back to Roman Republic, although the best examples are from the imperial times (Arch of Augustus at Susa, Arch of Titus).

A crucial factor in this development that saw a trend to monumental architecture was the invention of Roman concrete (also called opus caementicium), which led to the liberation of the shape from the dictate of the traditional materials of stone and brick.

Romanesque art is the art of Europe from approximately 1000 AD to the rise of the Gothic style in the 12th century, or later depending on region. The preceding period is known as the Pre-Romanesque period. The term was invented by 19th-century art historians, especially for Romanesque architecture, which retained many basic features of Roman architectural style – most notably round-headed arches, but also barrel vaults, apses, and acanthus-leaf decoration – but had also developed many very different characteristics.

In southern France, Spain, and Italy there was an architectural continuity with the Late Antique, but the Romanesque style was the first style to spread across the whole of Catholic Europe, from Sicily to Scandinavia. Romanesque art was also greatly influenced by Byzantine art, especially in painting, and by the anti-classical energy of the decoration of the Insular art of the British Isles. From these elements was forged a highly innovative and coherent style.

Sexual attitudes and behaviors in ancient Rome are indicated by art, literature, and inscriptions, and to a lesser extent by archaeological remains such as erotic artifacts and architecture. It has sometimes been assumed that "unlimited sexual license" was characteristic of ancient Rome, but sexuality was not excluded as a concern of the mos maiorum, the traditional social norms that affected public, private, and military life. Pudor, "shame, modesty", was a regulating factor in behavior, as were legal strictures on certain sexual transgressions in both the Republican and Imperial periods. The censors—public officials who determined the social rank of individuals—had the power to remove citizens from the senatorial or equestrian order for sexual misconduct, and on occasion did so. The mid-20th-century sexuality theorist Michel Foucault regarded sex throughout the Greco-Roman world as governed by restraint and the art of managing sexual pleasure.

Roman society was patriarchal (see paterfamilias), and masculinity was premised on a capacity for governing oneself and others of lower status, not only in war and politics, but also in sexual relations. Virtus, "virtue", was an active masculine ideal of self-discipline, related to the Latin word for "man", vir. The corresponding ideal for a woman was pudicitia, often translated as chastity or modesty, but it was a more positive and even competitive personal quality that displayed both her attractiveness and self-control. Roman women of the upper classes were expected to be well educated, strong of character, and active in maintaining their family's standing in society. With extremely few exceptions, surviving Latin literature preserves the voices of educated male Romans on sexuality. Visual art was created by those of lower social status and of a greater range of ethnicity, but was tailored to the taste and inclinations of those wealthy enough to afford it, including, in the Imperial era, former slaves.
