At first, the plan of Roman architecture was very simple (there were one or three halls, and finally a semi-circular back hall was added). In the 1 1 century, it has become complicated.
At this time, the purpose of architects is to take care of the stone surface of civil engineering, which hinders all the pursuit of grand scale. Therefore, this kind of building is low and narrow, and generally uses gravel to imitate the shape of bricks. However, it is precisely because builders are primarily concerned about the external cladding that people gradually use stone domes to replace wood beam frames that are prone to fire. In some parts of the hall, you can see the stone surface (back hall, small arch, etc.) ), its application in these parts is handy. Sometimes, for example, in St. Martin's Church in Canigou, Catalonia, bold builders extend their use to all buildings.
The change of masonry system led to the thinking of supporting materials, so the whole stone pillar was replaced by a cross-shaped pillar. These columns support columns or semi-exposed columns, which enhance the sense of rhythm inside the building. In the external decoration, we can also see the consideration of rhythm when increasing the height of the wall. Blind arcades (rumba shading) are separated by raised vertical lines (Rezner) to make the walls lively. Sometimes a few small windows are opened in the upper part of the wall. Manuscript illustrations have played a major role in the development of Roman art. This skill limit is much smaller than that of sculpture or architecture. Some precocious painting schools have produced some works that can be perceived as Roman characteristics since the beginning of the 20th century. It is manifested in the use of plain colors, relatively simple and naive, vivid narrative style and icons constantly mixed with abstraction and reality. The artist's effort is no longer to create illustrations, but to occupy as much space as possible.
