The great development from which the western provinces benefited in this period coincided with the birth and establishment of the characteristics of provincial art. The art of the
Roman provinces was based on the artistic tradition of
plebeian art, which was already widespread among the Roman middle class, usually called to form the nuclei of the new colonies of veterans. Among the most evident examples is that of production in the colony of
Aquileia. Works that were widespread in the provinces were funeral monuments decorated with reliefs, where the client's social status, businesses and public services were highlighted (as in the
Funerary Monument of Lusius Storax). The portraits in these works are almost always generic, without real individualized details. As a result, it is often useless to try to date them based on the hairstyles and styles of the clothes depicted in the art. There are two main original trends observed in provincial art: The conception of figures carved in blocks, with accentuation of mass at the edges ("cubistic" conception, which had also existed in
Etruscan art and then disappeared in the
Republican era); and figures with expressions of a gentler nature.
Gaul Narbonensis Unique are the characteristics of the artistic production in
Gallia Narbonensis (
Saint-Rémy-de-Provence,
Carpentras,
Orange). The monuments of this province, whose dating has long been discussed, present a rich style, with greater spatial freedom even than the coeval monuments of Rome, with stylistic elements (such as the outline of the figures highlighted with a carved line) which appear in Rome only from the second century. Notable constructions include the
Mausoleum of the Julii, dated between 25 BC and 30 BC, and the
Triumphal Arch of Orange from 26 AD. File:Glanum-mausolee.jpg|
